Decoding Data in PHP: The Ultimate Guide to Reading File Stream Data to String in 2025 Reading file content into a string is one of the most common tasks in PHP development. Whether you're parsing configuration files like JSON or INI, processing uploaded documents, or consuming data from streams and APIs, being able to efficiently and correctly read file data into a string is essential. With PHP 8.x, developers have access to mature, robust file handling functions, but choosing the right one—and understanding how to handle character encoding, memory efficiency, and errors—is key to writing performant and reliable code. In this comprehensive guide, we’ll walk through the best ways to read file stream data into a string in PHP as of 2025, complete with modern practices, working code, and real-world insights. Why Read File Stream Data to String in PHP? There are many scenarios in PHP applications where you need to convert a file's contents into a string: Parsing Configuration Files: Formats like JSON, INI, and YAML are typically read as strings before being parsed into arrays or objects. Reading Text Documents: Applications often need to display or analyze user-uploaded documents. Processing Network Streams: APIs or socket streams may provide data that needs to be read and handled as strings. General File Processing: Logging, data import/export, and command-line tools often require reading file data as text. Methods for Reading and Converting File Stream Data to String in PHP 1. Using file_get_contents() This is the simplest and most widely used method to read an entire file into a string. ✅ How it works: It takes a filename (or URL) and returns the file content as a string. 📄 Code Example: phpCopyEdit 📌 Pros: Very concise. Ideal for small to medium-sized files. ⚠️ Cons: Loads the entire file into memory—can be problematic with large files. Error handling must be explicitly added (@ or try/catch via wrappers). 2. Using fread() with fopen() This method provides more control, allowing you to read file contents in chunks or all at once. 📄 Code Example: phpCopyEdit 📌 Pros: Greater control over how much data is read. Better for handling large files in chunks. ⚠️ Cons: Requires manual file handling. filesize() may not be reliable for network streams or special files. 3. Reading Line-by-Line Using fgets() Useful when you want to process large files without loading them entirely into memory. 📄 Code Example: phpCopyEdit 📌 Pros: Memory-efficient. Great for log processing or large data files. ⚠️ Cons: Slower than reading in one go. More code required to build the final string. 4. Using stream_get_contents() Works well with generic stream resources (e.g., file streams, network connections). 📄 Code Example: phpCopyEdit 📌 Pros: Works with open file or network streams. Less verbose than fread() in some contexts. ⚠️ Cons: Still reads entire file into memory. Not ideal for very large data sets. 5. Reading Binary Data as a String To read raw binary data, use binary mode 'rb' and understand the data's encoding. 📄 Code Example: phpCopyEdit 📌 Pros: Necessary for binary/text hybrids. Ensures data integrity with explicit encoding. ⚠️ Cons: You must know the original encoding. Risk of misinterpreting binary data as text. Handling Character Encoding in PHP Handling character encoding properly is crucial when working with file data, especially in multilingual or international applications. 🔧 Best Practices: Use UTF-8 wherever possible—it is the most compatible encoding. Check the encoding of files before reading using tools like file or mb_detect_encoding(). Use mb_convert_encoding() to convert encodings explicitly: phpCopyEdit$content = mb_convert_encoding($content, 'UTF-8', 'ISO-8859-1'); Set default encoding in php.ini:

iniCopyEditdefault_charset = "UTF-8" Be cautious when outputting string data to browsers or databases—set correct headers (Content-Type: text/html; charset=UTF-8). Error Handling in PHP File Operations Proper error handling ensures your application fails gracefully. ✅ Tips: Always check return values (fopen(), fread(), file_get_contents()). Use try...catch blocks if using stream wrappers that support exceptions. Log or report errors clearly for debugging. 📄 Basic Error Check Example: phpCopyEdit Best Practices for Reading File Stream Data to String in PHP ✅ Use file_get_contents() for small files and quick reads. ✅ Use fread()/fgets() for large files or when you need precise control. ✅ Close file handles with fclose() to free system resources. ✅ Check and convert character encoding as needed. ✅ Implement error handling using conditionals or exceptions. ✅ Avoid reading huge files all at once—use chunked or line-by-line methods. ✅ Use streams for remote sources (e.g., php://input, php://memory). Conclusion Reading file stream data into a string is a foundational PHP skill that underpins many applications—from file processing to configuration management and beyond. PHP 8.x offers a robust set of functions to handle this task with flexibility and precision. Whether you’re using file_get_contents() for quick reads, fgets() for memory-efficient processing, or stream_get_contents() for stream-based applications, the key is understanding the trade-offs and ensuring proper character encoding and error handling. Mastering these techniques will help you write cleaner, safer, and more efficient PHP code—an essential skill for every modern PHP developer. 📘 External Resources: PHP: file_get_contents() - Manual PHP: fread() - Manual PHP: stream_get_contents() - Manual

#Php json decode as object how to#

Let’s see how to do it in practice with a few examples. There exist specific built-in functions that allow encoding and decoding JSON data. The data structures of JSON are identical to PHP arrays. Follow the steps and you’ll manage to meet your goal easily. Chapter 2 JSON encoding Creating a JSON object with PHP is simple: You just need to use the jsonencode () function. In this snippet, you can find a step-by-step guide on how to create and parse JSON data with PHP. depth: It states the recursion depth specified by user. Decode a JSON object received by your PHP script.If it is true then objects returned will be converted into associative arrays. Normally, jsondecode() will return an object of stdClass if the top level item in the JSON object is a dictionary or an indexed array if the JSON object.

Like, convert JSON string to array PHP, convert JSON string to multidimensional array PHP and JSON decode and access object value PHP. You can also turn your own data into a well-formatted JSON string in PHP with the help of the jsonencode () function. Be wary that associative arrays in PHP can be a 'list' or 'object' when converted to/from JSON, depending on the keys (of absence of them). When decoding that string with jsondecode, 10,000 arrays (objects) is created in memory and then the result is returned. In this tutorial, we will take examples using the json_decode() function.

What Exactly Are Yii2 Helpers Indicate?

In the series "Programming With Yii2," we walk readers through the Yii2 Framework for PHP. In this tutorial, we will provide a brief overview of helpers. Helpers are simple-to-extend modules in Yii that group together frequently used libraries for managing things like text, files, images, URLs, and HTML.

Additionally, we'll demonstrate how to create a helper in Meeting Planner, the topic of our Envato Tuts+ startup series.

Numerous Yii classes simplify common coding operations like manipulating strings or arrays, creating HTML code, and other similar activities. The Yii helpers namespace contains these static helper classes that are all organised (meaning they contain only static properties and methods and should not be instantiated).

In the Yii releases, you'll find the following fundamental helper classes:

ArrayHelper

Console

FileHelper

FormatConverter

Html

HtmlPurifier

Imagine (provided by yii2-imagine extension)

Inflector

Json

Markdown

StringHelper

Url

VarDumper

Let's move forward to the deep explanation of Helper Libraries for Yii2

Helpers are simply coding help modules with a specific theme. The helpers that come with Yii2 are listed here; this list is currently a little more recent than the documentation and menus:

With features like safely locating values online, mapping, merging, and more, ArrayHelper makes working with arrays simpler.

Input, output, and command-line functionality are all supported by the console.

The essential file management features of PHP are expanded by FileHelper.

Among the formats that FormatConverter translates, dates are currently its main focus.

Frequently used HTML tags are dynamically generated by HTML.

By removing user-input text, HtmlPurifier increases security.

Imagine now has the ability to manipulate images thanks to the yii2-imagine plugin.

Inflector offers practical string methods that are useful for common transformations.

A programme called JSON is used to encode and decode JSON data.

A conversion tool for markdown is called Markdown to HTML.

Natas: Level 11

This level once again focuses on cookies, and it took me a good while to figure out. The main page allows the user to input a colour, which will the change the background of the page to said colour when submitted.

Digging into the provided sourcecode, we see that an array of key value pairs is json encoded, xor encrypted and then base64 encoded, before being stored as a cookie called ‘data’ on the users computer.

The most difficult part of this level was understanding the properties of xor encryption. Thankfully Richard touched on it a bit in one of the online lectures for the course that I’d watched. I also managed to find some more information about it on this site: https://www.hackthis.co.uk/articles/the-xor-cipher. So in order to solve this level, we need to make use of the property that when something is xor’d twice, it will be deciphered.

My main goal is to find the censored ‘$key’ variable used in the xor_encrypt function. Since we know that the xor of the json encoded data (e.g. $defaultdata) and $key is equal to the ‘data’ cookie base64 decoded, we can use this information the derive the $key.

Making use of the xor_encrypt function provided in the code and with a bit of trial and error, I used an online php evlauator to get this result:

So from this we can derive that the $key is “qw8J”. Now we can create our own cookie, setting ‘showpassword’ to ‘yes’. 

Changing the data cookie and refreshing the page gets us the password to the next level.

I really felt like this level was quite challenging at first. However, after spending more time understanding the code and xor encyption, the solution kinda clicked in my head.

How to Incorporate External APIs in Your WordPress Theme or Plugin

APIs can help you to add functionality to your WordPress plugins and themes. In this tutorial I will show you how to use any API (whether it be from Flickr, Google, Twitter, and so on) with WordPress. You will learn how to connect, collect data, store and render–everything you need to know to extend your plugin or theme with new functionality!

We will use Flickr as an example, creating a simple widget that displays the latest Flickr images in order of username.  

Wait, What’s an API?

“API” stands for Application Programming Interface; an intermediary between applications, allowing them to communicate, sending information back and forth in real time. We’ll be using a Web API, one which uses HTTP to fetch data from a remote location on the internet somewhere.

“APIs are used by software applications in much the same way that interfaces for apps and other software are used by humans.” – David Berlind, ProgrammableWeb

If you want to get an even clearer idea of what APIs are before we dive into our tutorial, here are some more resources to help you:

Let’s begin by organizing our working environment. Start by downloading the Postman app, which provides an API development environment that makes it easy to connect, test, and develop any API. For individuals and small teams it’s completely free.

We’re going to build a widget in a simple WordPress plugin, so make sure you have WordPress installed.

2. Code the Plugin Basics

To start let’s create a simple plugin called flickr-widget. Create a folder with that name and create a flickr-widget.php file in it. At the top of the file place the following code (feel free to change the Author and URIs with your own details):

/* Plugin Name: Flickr widget Plugin URI: https://www.enovathemes.com Description: Display recent Flickr images Author: Enovathemes Version: 1.0 Author URI: http://enovathemes.com */ if ( ! defined( 'ABSPATH' ) ) { exit; // Exit if accessed directly }

Note: this is rudimentary plugin, so I won’t load a language file or create any additional parameters. 

Put the freshly created plugin folder inside your WordPress install: wp-content > plugins. You can now activate it from within the WordPress admin dashboard > plugins. You won’t see any changes to your WordPress because we haven’t actually added any functional code.

A Note on Using APIs

Before we go any further, let me quickly mention API use. Any service whose API you want to use will have documentation; I highly recommend you look closely at it. You can use APIs with all kinds of development languages and often get data back in any format you need: PHP, JSON, Java etc. Good documentation will contain detailed information on how to connect to the API, with instructions for each language, and also the main API endpoints (an endpoint is one end of a communication channel).

Web APIs are typically categorized as being either SOAP or REST. SOAP relies solely on XML to provide messaging services, while REST offers a more lightweight method, using URLs in most cases to receive or send information. In our example we will use a REST API.

Programming Fundamentals

What Does REST Mean?

3. Configure and Test API with Postman

So, here is our plan:

Configure and test API with Postman

Connect, collect, and format data from Flickr REST API

Cache the data with WordPress transients

Let’s refer to the Flickr API documentation. Under the Request Formats section you have REST, XML-RPC, SOAP. We need the REST. Click it and you will see an example of a general Flickr REST API Endpoint: https://www.flickr.com/services/rest/.

With the Flickr REST API we can GET, POST, and DELETE any Flickr data we want. Copy the sample endpoint and paste it into Postman (make sure your request type is set to GET). 

Click the Send button and... error! 

The sample request included the compulsory Flickr API method, but we didn’t specify the API key that is required in order to connect (keys are used to track and control how an API is being used, for example to prevent malicious use or abuse of the API as defined perhaps by terms of service).

4. Get API Key

Having established that we need an API key, let’s go and get one. In order to create one you will first need to have a Flickr/Yahoo account. Once you’ve entered the API dashboard click on the link create your first:

After that click on the Request an API Key. Many API providers have their own specific terms on API usage. Some limit access, others have light and pro versions, or commercial and non-commercial. Sometimes API keys are provided after manual approval; it depends entirely on the API provider. I have chosen Flickr, because it has simple API requirements. For example, Twitter requires a detailed description of the app you want to build before providing an API key, and this is then reviewed by the review team. 

That said, click on the Apply for a non-commercial key button and provide some basic info on the app name.

Once you’ve submitted the request you will get the API key (which identifies you) and secret code (which proves you are who you say you are) immediately. Keep these details safe!

5. Set the Request Parameters

Now we will need a method to request data. From the Flickr API documentation we can see that Flickr has tons to choose from. Some methods, like image posting, or deleting, require authentication. Flickr uses OAuth for this; an open, simple, and secure protocol that enables applications to authenticate users and interact with API providers on their behalf. The end user’s information is securely transferred without revealing the identity of the user.

For now, we’ll use simple methods that don’t require oAuth. Click on flickr.photos.getRecent method to see what’s required. This method does not need authentication, but it does take several arguments: api_key (required), extras, per_page, page. Let’s make a simple request in Postman using our parameters:

API general endpoint - https://flickr.com/services/rest

API key - f49df4a290d8f224ecd56536af51FF77 (this is a sample API key which you’ll need to replace with your own)

Method - flickr.photos.getRecent

It will look like this:

https://www.flickr.com/services/rest/?api_key=f49df4a290d8f224ecd56536af51FF77&method=flickr.photos.getRecent

This will return the list of recent public images from Flickr in XML format. 

XML format

I always set data format to auto to let Postman decide what format the data is. With Postman you have several data format options: JSON (my favorite), XML, HTML and Text. Flickr returns data in XML format, but this is not a problem for us, as we can add an additional parameter to get data in JSON &format=json:

JSON format

6. Connect, Collect, and Format Data

Now we know how to request data using the REST API, let’s build our WordPress Flickr widget. In the plugin’s main PHP file paste the widget code. I won’t cover the specifics of WordPress widget creation in this tutorial as our focus is different. We have a learning guide Introduction to Creating Your First WordPress Widget by Rachel McCollin which should get you up to speed if you need it.

In the WordPress admin navigate to Appearance > Widgets and add the “Photos from Flickr” widget to a widget area. Now if you go to the front-end you will see the widget title, but no results just yet. 

Back in our plugin PHP file, here we render the widget output itself. We have our API key, and the method, and the format we’re looking for. Now we will need to make sure the Flickr user id is provided, and the number of photos the user wants to fetch. These are are gathered from the widget settings.

Note: to get a Flickr user id use this service. I am using envato as the username, and the id is 52617155@N08. Enter the following code inside IF statement:

$url = 'https://www.flickr.com/services/rest/'; $arguments = array( 'api_key' => 'f49df4a290d8f224ecd56536af51FF77', 'method' => 'flickr.people.getPublicPhotos', 'format' => 'json', 'user_id' => $user_id, 'per_page'=> $photos_number, ); $url_parameters = array(); foreach ($arguments as $key => $value){ $url_parameters[] = $key.'='.$value; } $url = $url.implode('&', $url_parameters);

At this point we can knit together the final REST API endpoint url with all the arguments we’ve collected. 

Now we’ll make an API request with the file_get_contents() php function:

$response = file_get_contents($url); if ($response) { print_r($response); }

If you now go to the front-end you will something like this outputted:

jsonFlickrApi({"photos":{"page":1,"pages":1033,"perpage":1,"total":"1033","photo":[{"id":"15647274066","owner":"52617155@N08","secret":"2ee48c3fe9","server":"3940","farm":4,"title":"Halloween 2014 at Envato in Melbourne","ispublic":1,"isfriend":0,"isfamily":0}]},"stat":"ok"})

Our request was successful and returned useful data, so now let’s decode and format it. We’ll begin by cleaning up the JSON string–first by removing the wrapper (jsonFlickrApi({...});) with a str_replace. Then we’ll decode the JSON url:

$response = str_replace('jsonFlickrApi(', '', $response); $response = str_replace('})', '}', $response); $response = json_decode($response,true);

Now if we print our results we will see an associative array with data. When we’re ready we can loop through that array and create the data output structure. But first, take a closer look at the small parameter stat. According to the Flickr documentation this indicates the response status. So, before creating the structure of the widget let’s use this status to make sure we have the correct data. Add an IF statement: 

if ($response['stat'] == 'ok') { // code here… }

Create an empty array before the IF statement. This array will then be used to contain the collected data:

$response_results = array();

Your foreach loop should now look like this:

if ($response['stat'] == 'ok') { foreach ($response['photos']['photo'] as $photo) { $response_results[$photo['id']]['link'] = esc_url('//flickr.com/photos/'.$photo["owner"].'/'.$photo["id"]); $response_results[$photo['id']]['url'] = esc_url('//farm'.$photo["farm"].'.staticflickr.com/'.$photo["server"].'/'.$photo["id"].'_'.$photo["secret"].'_s.jpg'); $response_results[$photo['id']]['alt'] = esc_attr($photo["title"]); } }

Here we loop through each photo object in the photos array from our response data. Our widget needs the following information to function properly:

Image absolute URL

Image link to Flickr

Image description/alt text

Examine this page and you will understand why I used the given structure. Here you will find the detailed information on how to create the image path and image link. 

Create Widget Output

Now our $response_results array contains the exact data we need to create our widget:

if (!empty($response_results)) { $output = ''; $output .= '<ul class="widget-flickr-list">'; foreach ($response_results as $photo) { $output .= '<li>'; $output .= '<a href="'.$photo['link'].'" target="_blank">'; $output .= '<img src="'.$photo['url'].'" alt="'.$photo['alt'].'" />'; $output .= '</a>'; $output .= '</li>'; } $output .= '</ul>'; echo $output; }

We begin by making sure our response is not empty. After that we create an unordered list, storing it in $output, then loop through each image, adding a wrapper link, all the other details, and finally outputting the whole thing with echo;.

If you now go to the site front-end you will see a list of images! 

Let’s add some basic styling with CSS to make it look better.

Create an empty flickr-widget.css file in the root plugin folder. In the top of the plugin file paste the following code:

if ( ! defined( 'ABSPATH' ) ) { exit; // Exit if accessed directly } function register_script(){ wp_register_style('widget-flickr', plugins_url('/widget-flickr.css', __FILE__ )); } add_action( 'wp_enqueue_scripts', 'register_script' );

Then, inside the IF statement at the very top add the code:

if (!empty($response_results)) { wp_enqueue_style('widget-flickr');

Inside the css file add basic styling:

.widget-flickr-list { list-style: none; margin:0 -4px 0 -4px; padding: 0; } .widget-flickr-list:after { content: ""; clear: both; } .widget-flickr-list li { display: block; float: left; width: 25%; margin:0; padding: 4px; }

Now it looks much better!

Bonus: Cache the Data with WordPress Transients

At this stage we’ve finished the widget, but there is one more little thing that will take our development to the next level: caching. 

Any API request uses your site’s resources and increases load time. Each browser reload will send an API request, which could be multiple users at the same time. What if for some reason your API provider host is down? Your site will suffer load difficulties. The solution is to cache the results and update at a give time interval. So the first time a user visits our page the API request will be sent, but the next time, or with another user, we won’t need to send an API request but instead fetch the results from our site cache. 

Let’s modify the widget code to cache results:

if (!empty($flickr_id)) { $api_key = 'f49df4a290d8f224ecd56536af51FF77'; $transient_prefix = esc_attr($flickr_id . $api_key); if (false === ($response_results = get_transient('flickr-widget-' . $transient_prefix))) { $url = 'https://www.flickr.com/services/rest/'; $arguments = array( 'api_key' => $api_key, 'method' => 'flickr.people.getPublicPhotos', 'format' => 'json', 'user_id' => $flickr_id, 'per_page' => $photos_number, ); $url_parameters = array(); foreach ($arguments as $key => $value) { $url_parameters[] = $key . '=' . $value; } $url .= '?' . implode('&', $url_parameters); $response = file_get_contents($url); if ($response) { $response = str_replace('jsonFlickrApi(', '', $response); $response = str_replace('})', '}', $response); $response = json_decode($response, true); $response_results = array(); if ($response['stat'] == 'ok') { foreach ($response['photos']['photo'] as $photo) { $response_results[$photo['id']]['link'] = esc_url('//flickr.com/photos/' . $photo["owner"] . '/' . $photo["id"]); $response_results[$photo['id']]['url'] = esc_url('//farm' . $photo["farm"] . '.staticflickr.com/' . $photo["server"] . '/' . $photo["id"] . '_' . $photo["secret"] . '_s.jpg'); $response_results[$photo['id']]['alt'] = esc_attr($photo["title"]); } if (!empty($response_results)) { $response_results = base64_encode(serialize($response_results)); set_transient('flickr-widget-' . $transient_prefix, $response_results, apply_filters('null_flickr_cache_time', HOUR_IN_SECONDS * 2)); } } } else { return new WP_Error('flickr_error', esc_html__('Could not get data', 'your-text-domain')); } } if (!empty($response_results)) { $response_results = unserialize(base64_decode($response_results)); wp_enqueue_style('widget-flickr'); $output = ''; $output .= '<ul class="widget-flickr-list">'; foreach ($response_results as $photo) { $output .= '<li>'; $output .= '<a href="' . $photo['link'] . '" target="_blank">'; $output .= '<img src="' . $photo['url'] . '" alt="' . $photo['alt'] . '" />'; $output .= '</a>'; $output .= '</li>'; } $output .= '</ul>'; echo $output; } }

I won’t describe what the transient is and how it works, just what it does. Any time the widget is rendered we first check if the transient is in place; if it is present we fetch results from transient, but if not, we make an API request. And each two hours our transient expires, in order to keep our latest Flickr images actual and up to date. 

With the WordPress plugin Transients Manager you can even see what your cached Flickr API request results look like:

And the final touch here is to remove transient for every widget update. For example, if you want to change the number of images displayed, or change the username, you’d need to make a new API request. This can be done with the widget_update_callback WordPress filter, or the widget class public function update:

public function update($new_instance, $old_instance) { $instance = $old_instance; $instance['title'] = strip_tags($new_instance['title']); $instance['photos_number'] = strip_tags($new_instance['photos_number']); $instance['flickr_id'] = strip_tags($new_instance['flickr_id']); $api_key = 'f49df4a290d8f224ecd56536af51FF77'; $transient_name = 'flickr-widget-' . esc_attr($instance['flickr_id'] . $api_key); delete_transient($transient_name); return $instance; }

Conclusion

That was a lot of effort, but now you know how to work with WordPress and APIs! If you enjoyed this post and would like to see additional tutorials on APIs or transients, let me know in the comments section.

LEARN ABOUT JSON ENCODE AND DECODE IN PHP

New Post has been published on http://blog.openwebsolutions.in/learn-json-encode-decode/

LEARN ABOUT JSON ENCODE AND DECODE IN PHP

JSON is basically used when we want to send back data to the client server. JSON ENCODE means if the data type is in array format then it actually turns into JSON OBJECT, and JSON DECODE is vice versa to the JSON encode.

here I can show you a small example of JSON ENCODE

$data = array(

    ‘name’ => ‘anwesha’,

    ‘gender’ => ‘Female’,

  ‘address’=>’agarpara’

);

$json = json_encode($data);

this way $data which is array datatype turns into JSON object

here is also one small example of JSON  DECODE

$json = “ ‘anwesha’: ‘Female‘ ”; json_decode(json);

in this way $json turns into json array.

XenForo 2.0.12 - Upgrade

XenForo 2.0.12 is now available for all licensed customers to download. We recommend that all customers running previous versions of XenForo 2.0 upgrade to this release to benefit from increased stability. This version makes a number of changes to improve compatibility with PHP 7.3.0. However, at this time, we do not recommend using PHP 7.3.0 in production due to a bug that can cause code to execute incorrectly, potentially leading to data loss. We believe this bug will be resolved in PHP 7.3.1 when it's released. Download XenForo 2.0.12 Some of the changes in XF 2.0.12 include: Improve PHP 7.3 compatibility. If available and different from the server version, grab a more detailed version for the Server environment report. If the $_SERVER['SERVER_SOFTWARE'] value isn't available or valid then just don't display that entry in the report, because it's mostly not essential. Adds some additional phrases for the "Server environment report" Fix an issue which affects building add-on releases on Windows where local paths included a leading slash. Incrementally update the job state of the Sitemap job so that a fatal error shouldn't disrupt the process and introduce corrupted/duplicate items. Adjust error message given when attempting to edit a user's permissions for a content type without a valid user_id. Standardize the locale information used by PHP. Use a different approach to loading icons on the add-ons list in the Admin CP. To avoid issues with multiple database connections, the icon image data is instead converted to a data URI. User upgrades should not check canPurchase() before processing a payment that has been received, as this method is really only for limiting the UI/purchase setup. Add some additional trusted IP ranges for Google. Ensure 'nullable' entity property is reflected in generated code Ensure node navigation entries use their assigned title Ignore custom field errors during admin edit and include custom field title with errors Convert warning notes field to structured text Correctly apply admin user message leave options Prevent new messages being duplicated in Firefox Ensure multi quote quotes are inserted into the correct editor Hide 'Start a new conversation' link if visitor doesn't have permission to start conversations. Allow permanent redirects to be stickied and unstickied. Remove extra save call when ignoring member Remove UTC check from server environment report and link PHP version to phpinfo page Prevent loading of Setup.php if addon.json requirements aren't met Make xf-dev:entity-class-properties CLI command correctly handle subdirectories Return 'complete' response from UserGroupPromotion job if no active promotions are found. Ensure 'From name' and 'From email' fields are applied when batch emailing users Hide editor draft menu from guests Ensure cron entries run at zero valued time units if multiple time values are selected. Check for missing hash in IPSForums3x authentication handler. Add missing hint parameter to discouraged checkbox on user edit page Remove invalid relation from SpamTriggerLog entity Use content type phrase when rebuilding the search index Fix incorrect URL on conversation message likes list Fix broken 'Delay duration' option for floating notices Allow invalid users to be unfollowed Re-add explain text in the user_edit form to clarify non-valid user states behaviour. Include table name in message for any exception occurring in SchemaManager methods. Implement custom stack trace builder to mask passwords in method arguments Add deleted item styling to news feed items When restoring spam cleaned threads, ensure threads which were originally moved are restored back to the correct forum. Return an error phrase upon invalid callback validation when performing spam clean actions. Note that the method name switches to ucfirst(\XF\Util\Php::camelCase($action)) in XF 2.1 but remains as ucfirst($action) in XF 2.0. When handling a Stripe webhook that is missing required metadata, when attempting to find a previous related log, ensure said log actually contains a purchase_request_key. Improve BB code parsing of incomplete tags within plain-child tags. Migrate user field criteria during upgrade from XF 1.x to 2.x By default, do not allow cookies to be retrieved as arrays to prevent unexpected behavior. (Array support can now be opted into explicitly.) Prevent an error when trying to delete a payment profile when there is an invalid purchasable definition. Track when a preview is pending to prevent multiple simultaneous preview loads. Prevent a PHP notice when deleting a poll for a thread started by a guest Include breadcrumb in edit history view and compare templates. Pass unused $ellipsis variable into wholeWordTrim. Prevent long select options from causing overflow on iOS. Enable the HTML to BB code simplification process to handle additional situations Resolve some situations where the new messages indications while composing a reply wouldn't take you to the expected location. Validate advertisement html before saving. Prevent tel/sms links being converted to bbcode Remove the insert icode option when extended text formatting is disabled. Allow end user modification to the "allow this BB code in signatures" option on add-on-defined custom BB codes. Call the canPurchase method instead of can_purchase in UserUpgrade::getFilteredUserUpgradesForList. Correctly combine multiple custom field-related limits to the user and thread searchers. Correctly apply the "not in secondary groups" user search condition (users cannot be in any of the listed groups). When building a release and testing a JSON, only consider an error if decoding the build.json does not return an array. When submitting spammers to StopForumSpam, convert binary IP address to readable string. When saving style templates through the admin UI, force version/last_edit_date to be updated like XF 1.x When merging threads, always redirect to the target thread. Fix currency code for Belarusian Ruble (BYR => BYN) No longer cache the preview container object in the PreviewClick handler. If there are multiple handlers per page, the cached container becomes incorrect if using different handlers. When form filling, if the control is a textarea with a textarea-handler, trigger its update method to ensure the textarea is resized appropriately. Prevent an array-to-string conversion when throwing a bulkInsert exception if a missing column is detected. Ensure that the user following cache cannot include your own user ID. Add missing mod_log.thread_poll_reset phrase. Attempt to exclude dot files/directories from our vendor dependencies. Number boxes are too wide and cause units to overflow their container, fixed with max-width. Add "Please do not reply to this message" text to outgoing conversation emails. Reassign user group changes when merging users Ensure PasswordChange service errors on any UserAuth error. Fetch more threads for new threads widget Ensure exceptions in sub-processes stop execution, and always exit with non-zero error code on error. Make Disabler system compatible with select options. Ensure FieldAdder handles Disabler elements correctly Ensure prefix of destination thread is shown in moved post alert. Trigger change event on select when prefix selected Remove the "mixed" stuff from CodeMirror's PHP mode so that the opening tag is no longer required. Update broken link to Apple support in cookie help page text (and in XF 1.5). Adjust top border radii of blocks within overlays. Allow non-user selectable styles to be used for the email style. Also, add several email-related style properties to allow email colors to be overridden more directly, without creating a new style. Implement a "notice watcher" system for bottom fixed notices. This calculates the total visible notice height in the bottom fix location and adds a footer margin to the same value so that no content can be covered by the notice(s). Adjust how we parse search query modifiers to be more strict. (- and + require whitespace before and none after, | requires whitespace on both sides. Don't parse doubled up modifiers.) Adjust trophies phrase capitalization Include no_date_limit in the rel=canonical link for forums when needed Attempt to reduce cases where conversation reply_count values could potentially get out of sync. Allow the reply count and other parts to be rebuilt via the conversation rebuild tool. By default, reject email addresses as invalid if there are no dots in the domain part. Add a bit of left padding on contentRow-suffix elements. Include the forum a thread is in in the RSS feeds (only for global feeds) Fix add-on development data not being removed as expected when the last entry of a type has been removed. (The metadata JSON file must still exist.) Relax URL validation a tiny bit, notably don't block adjacent path separators in the path section. Ensure phrase is escaped in HTML attribute. Ensure usage of phrase within HTML attribute is escaped. In the AbstractSearcher ensure that the day end value is converted properly to the end of the day. Never allow the XF add-on to appear in add-on lists. Handle avatar deletes via the spam cleaner for gravatars too. Make add-on action finalization more robust when uninstalling legacy add-ons. When importing dev output, ignore any invalid columns. Add some block border radius to the member header block so that it fits within its parent block. Ensure permissions are rebuilt on add-on active change. Update child navigation entries directly when the parent ID changes to ensure dev output is written correctly. Use the correct maxlength value for the public navigation structure. Additionally, bump AdminNavigation ID lengths up to 50 from 25. Add support for partial indexes to schema manager conflict resolution system Fix multiple issues that make it hard to use XF\Import\Data\AbstractEntityData Consistently use code paths which result in the canView method of the report entity (rather than the handler) being used. The following public templates have had changes: account_upgrades core_contentrow.less core_input.less core_overlay.less editor_base.less edit_history_compare edit_history_view forum_view PAGE_CONTAINER quick_reply_macros thread_save_draft warning_info Where necessary, the merge system within the "outdated templates" page should be used to integrate these changes. As always, new releases of XenForo are free to download for all customers with active licenses, who may now grab the new version from the customer area. Note: add-ons, customizations and styles made for XenForo 1.x are not compatible with XenForo 2.x. If your site relies upon these for essential functionality, ensure that a XenForo 2 version exists before you start to upgrade. We strongly recommend you make a backup before attempting an upgrade. Current Requirements Please note that XenForo 2.0.x has higher system requirements than XenForo 1.x. The forthcoming XenForo 2.1.x release will have higher system requirements again (PHP 5.6). The following are minimum requirements: PHP 5.4 or newer (PHP 7.2 recommended) MySQL 5.5 and newer (Also compatible with MariaDB/Percona etc.) All of the official add-ons require XenForo 2.0. Enhanced Search requires at least Elasticsearch 2.0. Installation and Upgrade Instructions for XenForo 2.0 Full details of how to install and upgrade XenForo can be found in the XenForo 2 Manual. Note that when upgrading from XenForo 1.x, all add-ons will be disabled and style customizations will not be maintained. New versions of add-ons will need to be installed and customizations will need to be redone. We strongly recommended that you make a backup before attempting an upgrade. Once upgraded, you will not be able to downgrade without restoring from a backup.

Online JSON Tools Review

If you’re a savvy web developer, you have definitely searched on Google for tools like “url decode json” or “convert json to text”. And what do you usually get? You get garbage websites filled with ads, popups, blinking download buttons and tools that don’t really work.

The same problem was faced by Peter K. Rumins from Browserling. He decided to solve this problem once and for all by building a network of tools websites. These sites consist of thousands of simple tools that help to work with JSON, XML, CSV, YAML, PNG, JPG, Strings and even Mathematics. These tools are ads free, there are no configuration options and no ads.

OnlineJSONtools.com is one such website in the network and it helps developers to work with JSON data structures in the browser. The tools are so easy to use that all you have to do is enter JSON input and you instantly get the result you are looking for.

Currently Supported JSON Tools

Below is the list of all the tools that are currently available. Apart from that Browserling team is constantly working to add more tools such as JSON to BSON.

JSON Highlighter tool: JSON highlighter will give each token a different color. Values, keywords, brackets and also to special characters (like newlines, tabs, etc) get special colors. Let’s see a working version of JSON highlighter in an example:

You can see strings, object values and keys are in yellow color, blue color for numerical values, white color for arrays and objects, and grey color for invisible special characters.

It has some additional features that let you control highlighting of JSON:

Shows special characters, as in above example new line is represented by a “downstairs symbol”.

It will care about your matching brackets, it also highlights matching brackets if the cursor is near one.

It also shows the active line in gray color so that you can see more easily on which line the cursor is.

It also tells user not only the line number where is the error but also what is the error by highlighting it as shown in below example.

JSON Prettifier Tool: So here word “prettifier” itself describing this tool. This makes your JSON code well formatted with proper indentation. It will convert an ugly code to beautiful code.

Let’s see the use of the tool on a given problem where you have minified JSON input:

You can see from the above program the code in left block is not indented and not aligned but after using JSON prettifier it aligns the code in proper indentation and you can quickly understand it.

We can also define by the “number of spaces” and “number of tabs” to indent output with spaces and with tabs as shown below.

JSON Minifier Tool: It is a tool which removes all whitespaces and gives a JSON code that takes least space. It’s effective for transmitting less data and making faster web page load time.

JSON Validator Tool: This is an important tool that let you write a valid JSON code. It will point out where is the error and tell the programmer what the error is.

JSON Escaper Tool: JSON escaper helps the programmer to embed JSON in a string as it escapes all special symbols. So now you don’t need to worry about if you forget escape sequence code of any special character, because JSON escaper is here to help you.

JSON Unescaper Tool: JSON unescaper just reverse of the JSON escaper. It will return you a valid JSON object from a string version of JSON object.

JSON to XML Convertor Tool: This tool helps you to easily convert your JSON data into an XML documents and also allow us to make change in indentation for easier reading.

XML to JSON Convertor Tool: This tool gives us a very easy solution of converting an XML data into JSON documents.

JSON to YAML Convertor Tool: It let us convert our JSON structure to its equivalent YAML config file.

YAML to JSON Convertor Tool: A reverse version of JSON to YAML that transpiles YAML data to JSON config.

JSON to TSV Convertor Tool: The main feature of this tool is that it quickly converts our JSON code into text in tab separated values format.

TSV to JSON Convertor Tool: This tool let us do reverse action of previous and convert TSV columns into JSON objects.

JSON to CSV Convertor Tool: JSON to CSV convertor is similar to JSON to TSV but here the output is column separated values.

CSV to JSON Convertor Tool: This tool helps us convert CSV back to JSON in a just one click without installing any application or following any instructions.

JSON to BSON Convertor Tool: This tool helps us to represent our JSON code in binary-encoded format. This increases the efficiency in binary applications.

BSON to JSON Convertor Tool: It allow us to convert BSON, which is binary encoded JSON back to JSON format.

JSON to Image Convertor Tool: It helps to transforms our JSON code into a JPEG, PNG, GIF, BMP image. It basically screenshots the JSON code and gives you back a downloadable image.

JSON to Base64 Tool: It not only allows us to encode our JSON data to base64 code that’s used in webapps.

Base64 to JSON Tool: Simple and easy tool that decodes base64 data back to JSON format.

URL-encode JSON Tool: This is a fantastic tool that encodes our JSON objects into URL-encoding format by escaping all URL characters to percent-number-number format.

URL-decode JSON Tool: This tool transform our data back to JSON format from URL-encoded data by unescaping all URL-encoded sequences to regular characters.

JSON to Plain Text: The main feature of this tool is that it extracts plain text data from JSON code by removing all special JSON symbols and operators.

JSON Editor Tool: It provides us a clear interface in the browser to edit JSON in syntax-highlighted editor.

Upcoming JSON Tools

Mr. Rumins and his team at Browserling is also working on more new JSON tools. Here is the list of tools that will be available soon on the site:

Display JSON Statistics: Provide statistics about JSON objects and their complexity.

Flatten JSON: Flatten deep JSON structures into flat single depth objects.

Obfuscate JSON: Convert JSON to unrecognizable but still valid data.

Convert JSON to a HTML: Create HTML webpage from a JSON code.

Convert JSON to a Bencode: Convert JSON objects to B-encoded data that’s used in bittorrent protocol.

Convert JSON to a Latex Table: Create a Latex table code from a JSON data structure.

Truncate JSON: Cut off excessively large JSON data and make JSON the required length.

Convert JSON to Data URI: Encode JSON so that it can be used in URLs.

Convert JSON To a PHP Array: Create PHP code from JSON code.

Compare Two JSON Files: Compare two JSON files in the browser and find their differences.

If you found JSON tools useful and you would like to have more tools and new JSON features then please tell us know by commenting below.

I would like to thank whole Browserling team for building such handy online tools that is making the work easier for programmers like me and many others. A million and one thanks!

Channels from Pusher is a platform that allows you to give your apps seamless real-time data. 

In this post, I'll show you how to write the functional components of a very simple chat app. It's a stripped-down example, but you'll see how Channels can simplify the implementation of real-time communication in a web app.

Setting Up the Server

Our server application is a single PHP file called messages.php which will handle the POST requests coming from the browser. Our message handler will send the client’s messages to the Channels service, which will then broadcast those messages to other clients.

When using PHP for your server application, you want to download and use the Channels library, and you can install that library using composer and the following command:

composer require pusher/pusher-php-server

The code for messages.php is almost an exact copy of what you can find on the Getting Started page in your Channels dashboard. There are just a few modifications.

First, you need to require the autoload.php file to use the Pusher library:

require './../vendor/autoload.php';

Next, the data coming from the client is in JSON format, so we obviously want to decode it into a workable PHP array.

$data = json_decode(file_get_contents('php://input'), true);

We then want to set up our Pusher object so that we can then trigger an event.

$options = array( 'cluster' => 'us2' ); $pusher = new Pusher\Pusher( '427017da1bd2036904f3', 'c46fabbaf65c4c31686b', '534815', $options );

My PHP installation does not work if the encrypted option is enabled, so I omitted it from my code. Your mileage may vary, but it's important to note that the encrypted option determines whether or not the data sent between the server and Channels is encrypted. It has nothing to do with the connection between Channels and your clients—the client library handles that.

The final line of our server's code sends the message data to Channels:

$pusher->trigger('anon-chat', 'send-message', $data);

As with other server libraries, we pass three things to the trigger() method:

The channel name: anon-chat

The event name: send-message

The payload: $data

Notice that the channel and event names are different than the channel and event names used on the Getting Started page. You do not have to create new channels or define custom events in the dashboard; just use whatever channel and event names you want in your code.

Completing the Client

Our client is a web page with three Vue.js components powering the UI. The main component is called ChannelsChat, and it is where we will put our Pusher object that listens for send-message events in the anon-chat channel. Let's use the created hook.

created() { let pusher = new Pusher('427017da1bd2036904f3', { cluster: 'us2', encrypted: true }); let channel = pusher.subscribe('anon-chat'); channel.bind( 'send-message', function() {} // to be implemented later ); }

In this code, we create the Pusher object, subscribe to the anon-chat channel, and listen for send-message events.

Because this is a chat application, we need to store the message history so that whoever is using the application can see all the messages they received during their session. The easiest way to accomplish this is to store each message as an element in the array. So let's add a messages data property to this component, as shown in the following code:

data() { return { messages: [] } }

Then, when we receive a message, we'll simply push() it to our array, as shown in the following code:

channel.bind( 'send-message', (data) => this.messages.push(data.message) );

We'll then pass the messages to the MessageView component:

<message-view :messages="messages" />

Sending Messages

The last of our code belongs in the MessageSend component; when the user types a message and clicks the Send button, we need to send that data to messages.php.

First, let's make sure the user typed something into the text box. Otherwise, there's no need to do anything!

sendMessage(e) { if (!this.message) { return; } // to be continued...

The message property is bound to the <input/>'s value, so we'll use that to determine if we have any data.

Next, we send the POST request to message.php, and the data is an object with a message property.

// (continued) axios.post('/message.php', { message: this.message }).then(() => { this.message = ''; }).catch((err) => { alert(err); }); }

If the request is successful, we clear the message property's value, which in turn clears the <input/>'s value (remember that they're bound). If the request fails, an alert box tells the user that an error occurred.

That's it for the code. So open two browser windows and point them to index.php. Start sending messages and you should see both windows automatically update and display the messages.

Conclusion

As you can see, Channels makes it incredibly easy to quickly add real-time communication to your applications, and it didn't even require a lot of code! 

You also learned that you can create channels and events on the fly as you write your code. There's no need to set them up prior to using them. 

And finally, you learned how you can set up your applications to incorporate real-time communication. Simply handle incoming user input from your server, and trigger events based on that input.
