PHP / array_merge_recursive

Esta funcion nos permite unir varios arrays pero con un adicional si contiene arrays internos, espero les sea de utilidad!

Bienvenidos sean a este post, hoy veremos una funcion para los arrays. Esta funcion nos permite combinar varios arrays pero a diferencia de array_merge este tiene una caracteristica adicional, pero primero veamos como es su sintaxis: array_merge_recursive(array_1, array_2,..., array_N) Solamente le pasamos todos los arrays que deseamos unir pero como mencionamos tiene una particularidad ya que…

Array manipulation in PHP

PHP Certification Course, Array manipulation in PHP involves performing various operations on arrays, such as adding or removing elements, sorting, searching, and restructuring. PHP offers a rich set of array functions to facilitate these tasks. Here are some common array manipulation techniques:

Creating Arrays: Arrays in PHP can be created using square brackets [] or the array() construct. For example:phpCopy code$numbers = [1, 2, 3, 4, 5]; $fruits = array('apple', 'banana', 'cherry');

Adding Elements: To add elements to an array, you can use the assignment operator = or the [] notation. For example:phpCopy code$numbers[] = 6; // Adds 6 to the end of the $numbers array array_push($fruits, 'date'); // Adds 'date' to the end of the $fruits array

Removing Elements: Elements can be removed using functions like unset() or array manipulation functions like array_pop() and array_shift(). For example:phpCopy codeunset($numbers[2]); // Removes the element at index 2 $removedFruit = array_shift($fruits); // Removes and returns the first element

Merging Arrays: Arrays can be combined using functions like array_merge() or the + operator. For example:phpCopy code$combinedArray = array_merge($numbers, $fruits); $mergedArray = $numbers + $fruits; // Note: Keys are preserved

Sorting Arrays: Arrays can be sorted using functions like sort(), rsort(), asort(), ksort(), etc., based on different criteria such as value or key. For example:phpCopy codesort($numbers); // Sorts the array in ascending order ksort($fruits); // Sorts the array by keys

Searching in Arrays: Functions like in_array() and array_search() can be used to search for elements in an array. For example:phpCopy code$found = in_array('banana', $fruits); // Checks if 'banana' is in the $fruits array $index = array_search('cherry', $fruits); // Returns the index of 'cherry' in $fruits

Filtering Arrays: Functions like array_filter() allow you to create a new array with elements that meet specific criteria. For example:phpCopy code$filteredNumbers = array_filter($numbers, function($num) { return $num % 2 == 0; // Filters even numbers });

Iterating Over Arrays: Looping constructs like foreach and for are commonly used to iterate through arrays and perform operations on each element.

These are just a few examples of array manipulation techniques in PHP. Understanding these functions and techniques allows developers to effectively work with and manipulate arrays in their applications.

Insert an array into another associative array at a fixed place in PHP

Insert an array into another associative array at a fixed place in PHP

In an associate array, the order does not matter, because we are calling values by keys, but some times when we want keys to be in a particular order then things get complicated.

The Problem

If you have two arrays with random number of keys:

$array = array( 'minusone' => 'e', 'zero' => 'd', 'one' => 'a', 'two' => 'b', );

and then want to insert these two arrays:

$insert =…

[Laravel][Testing] Display clearly array not equals error messages

Problem

When assertEqual asserting was failed, I can’t not known where the path of properies is not match.

Example: Assume I have many configs(contains inputs and expected result) With bellow test, I will receive the bellow message.

private const CONFIGS = [ [ 'params' => [ 'level' => JlptRank::N4, 'parts_score' => [ JlptCategoryConstant::JLPT_VOCABULARY__VALUE => 50, JlptCategoryConstant::JLPT_READING__VALUE => 50, JlptCategoryConstant::JLPT_LISTENING__VALUE => 50, ] ], 'expect_return_value' => JlptRank::RANK_A ], // ... ];

Test code:

/** @test */ public function it_returns_expect_results() { foreach (self::CONFIGS as $config) { $this->assertEquals( $config['expect_return_value'], JlptRank::calculate_Jlpt_rank(...array_values($config['params'])) ); } }

Test result:

Failed asserting that two strings are equal. Expected :'C' Actual :'D'

It is hard to find where is the *config that happen don’t match.*

Solution

Merge inputs and expected results in to array, and comparsion it.

/** @test */ public function it_returns_expect_results() { foreach (self::CONFIGS as $config) { $this->assertEquals( json_encode($config), json_encode(array_merge($config, ['expect_return_value' => JlptRank::calculate_Jlpt_rank(...array_values($config['params']))])) ); } }

Test result will be:

Failed asserting that two strings are equal. Expected :'{"params":{"level":4,"parts_score":{"91":10,"93":60,"94":10}},"expect_return_value":"C"}' Actual :'{"params":{"level":4,"parts_score":{"91":10,"93":60,"94":10}},"expect_return_value":"D"}'

Now you can easily see which properties don’t match.

Introduction to the Drupal Unit-testing

You have added features to the site a few days later the customer called and told me that nothing works. You have 20 hours stuffing code and a bunch of times and go on klatsaete forms of testing to get everything working, but the brain perceives nothing and end up on the site added a broken piece. Or maybe you have a complex module with a bunch of interconnected functional, well or small, but with a lot of choices. In general, you have millions of reasons to come to the automated testing.

Use of automated testing can get rid of piles of routine operations on a regular functional testing code. To test the available AutoComplete forms and checking the result, control user access to various sections of the site and functionality, and much more.

What can we offer to test Drupal?

Testing modules and functionality in Drupal module by using SimpleTest. And, with version 7 is included in the kernel, so look the other way and do not make much sense.

Installation

To install you need to set Drupal and that the server was accessible library php-curl, with which the module implements parsing of pages. Once the module is copied to the server, you need to patch the kernel, the patch file is located in the root folder of the module. To use it you must click on the server from the root of the site:

patch-p0 <{path-to-folder-with-modules} / simpletest/D6-core-simpletest.patch Then you can just activate it in the tab with modules and you can view a list of available tests on the page admin / build / testing.

How does the SimpleTest?

In the beginning, it scans the folder modules in search of available tests, if it does not matter whether or not the module is active, the user sees and tests themselves and can not fulfill them including the corresponding module.

This is achieved thanks to the fact that, before starting the test SimpleTest creates a virtual installation of Drupal with a later and running. Already it activates the necessary modules and themes, which may differ from the installation of the current site. Further, in the software testing outsourcing services process tested caused a page or function, after which they validate and generate output information about the success or failure of the operation.

By the way, for each function testXXX setUp runs every time before performing the test.

The first test

Thus, we conclude the flood and move on to practice. In the first test we examine the creation of material such as Page, which is available in all installations. To do this we need:

Create a test file with the name imya_modulya.test and save it in the folder with the module. The file name specified in the tough SimpleTest.

Next, create the test itself:

<?php class OurModuleTest extends DrupalWebTestCase { / / Helper function, which we will generate a text with blanks and Blackjack protected function randomText ($ wordCount = 32) { $ Text =”; for ($ i = 0; $ i <$ wordCount; $ i + +) { $ Text .= $ this-> randomString (rand (4, 12)). ”; } return $ text; } / / Information about the test, which is displayed on the page of tests. public static function getInfo () { return array ( ‘Name’ => ‘Page creation test’, ‘Desc’ => ‘Testing page creation’, ‘Group’ => ‘Our tests’, ); } public function setUp () { / / Set the required modules $ Args = func_get_args (); $ Modules = array_merge (array (’help’, ’search’, ‘menu’, ‘node’), $ args); call_user_func_array (array (’parent’, ’setUp’), $ modules); / / Set the right user permissions $ Permissions = array (’access content’, ‘create page content’, ‘delete own page content’, ‘edit own page content’); / / Create a user with these rights and enter into the system $ User = $ this-> drupalCreateUser ($ permissions); $ This-> drupalLogin ($ user); } / / Testing a page public function testPageCreation () { $ Params = array ( ‘Title’ => $ this-> randomName (32) ‘Body’ => $ this-> randomText (), ); / / Call a Page Page $ This-> drupalPost (’node / add / page’, $ params, t (’Save’)); / / Check if the received input $ This-> assertText (t (’Page @ name has been created.’, Array (’@ name’ => $ params ['title'])), t (’ Page creation ‘)); } } ?>

Clear the cache and go to the page admin / build / testing. Now, there we see the drop-down tab "Our tests", which is available in a single test "Page creation test". By putting a tick on him to fulfill it. after the information is available to us "19 passes, 0 fails, and 0 exceptions". The fact that we wanted.

Now log out the user and then try to perform the test. To do this, create another test and call it testAnonymousPageCreation. From the previous test code will be different only in that we run before running $ this-> drupalLogout ()

/ / Test create page anonymous user public function testAnonymousPageCreation () { / / User Razloginivaem $ This-> drupalLogout (); $ Params = array ( ‘Title’ => $ this-> randomName (32) ‘Body’ => $ this-> randomText (), ); / / Call a Page Page $ This-> drupalPost (’node / add / page’, $ params, t (’Save’)); / / Check if the received input $ This-> assertText (t (’Page @ name has been created.’, Array (’@ name’ => $ params ['title'])), t (’ Page creation ‘)); }

Now the result of 29 passes, 5 fails, and 0 exceptions. However, this is not the result, which was worth getting. In this case, you need to check whether the user’s access is blocked to this page, this will be a successful test, this will modify the test:

/ / Test create page anonymous user public function testAnonymousPageCreation () { / / User Razloginivaem $ This-> drupalLogout (); / / Try to get the desired page $ This-> drupalGet (’node / add / page’); / / Check the server response to error 403 (Access denied) $ This-> assertResponse (403, t (’You have no permitions to this page .’)); }

Now the result: 30 passes, 0 fails, and 0 exceptions. Ok, now we know that unauthorized users can not get access to the creation of pages.

What’s next?

Next we have to teach myself to write code right away with the tests. SimpleTest provides enough functionality to solve many problems.

First, it helps to formalize the problem, because for the test to prescribe a clear success criteria.

Second mistake will be detected earlier and a fix will be spent significantly less time because there will be the exact information where and under what conditions the error appeared.

Third excluded mass of routine operations, in which to make a mistake and miss something important. And most importantly, always nice to know that everything he wrote is working as intended.

A small bonus

There is a set of small and major problems and issues related to testing with the help of this module, which you or come across or not, but we warn you:)

SimpleTest can not test JavaScript, therefore the functional jQuery, dynamic content spoofing, etc. test will not work :( The list of available tests (Assertions) is available here: http://drupal.org/node/265828 To form the module must be called View $ this-> drupalGet (), instead of drupalPost (). Example:

$ Params = array (’sorting’ => ’sorting_value’); $ This-> drupalGet (’find / wine-ratings’, array (’query’ => $ params));

Tests are available for inactive modules.

Establishment types, etc. should be brought to a separate module, and write all the necessary procedures in module_name.install.

If you create a separate module for testing, then the file should be added module_name.info hidden = TRUE, then the module can be invoked in the tests, but will not be available in the list.

Nodecomment module conflicts with the module comment, so you should edit the profiles \ default \ default.profile and remove it from the default settings.

And finally an extended version of the class DrupalWebTestCase, which added additional functions and features:

class ExtendedDrupalWebTestCase extends DrupalWebTestCase { protected $ admin_user; protected $ users; / / Helper function, which we will generate a text with blanks and Blackjack protected function randomText ($ wordCount = 32) { $ Text =”; for ($ i = 0; $ i <$ wordCount; $ i + +) { $ Text .= $ this-> randomString (rand (4, 12)). ”; } return $ text; } / / Change the current theme protected function setTheme ($ new_theme) { db_query ("UPDATE {system} SET status = 1 WHERE type = ‘theme’ and name = ‘% s’", $ new_theme); variable_set (’theme_default’, $ new_theme); drupal_rebuild_theme_registry (); } / / Generate file name to display a folder that is outside the temporary folder and SimpleTest can view the data after cleaning. protected function getOutputFile () { $ File_dir = file_directory_path (); $ File_dir .= ‘. / Simpletest_output_pages’; if (! is_dir ($ file_dir)) { mkdir ($ file_dir, 0777, TRUE); } return "$ file_dir / $ basename." . $ This-> randomName (10). ‘. Html’; } / / Write page protected function outputAdminPage ($ description, $ basename, $ url) { $ Output_path = $ this-> getOutputFile (); $ This-> drupalGet ($ url); $ Rv = file_put_contents ($ output_path, $ this-> drupalGetContent ()); $ This-> pass ("$ description: Contents of result page are". L (’here’, $ output_path)); } / / Write the last on-screen display protected function outputScreenContents ($ description, $ basename) { $ Output_path = $ this-> getOutputFile (); $ Rv = file_put_contents ($ output_path, $ this-> drupalGetContent ()); $ This-> pass ("$ description: Contents of result page are". L (’here’, $ output_path)); } / / Write variable to file protected function outputVariable ($ description, $ variable) { $ Output_path = $ this-> getOutputFile (); $ Rv = file_put_contents ($ output_path, ‘<html> <body> <pre>’. Print_r ($ variable, true ).’</ pre> </ body> </ html> ‘); $ This-> pass ("$ description: Contents of result page are". L (’here’, $ output_path)); } }

The best code snippets Wordpress for your website

Before publishing this post, we already know how to add PHP functions in Wordpress via using tools. However, I want to share with you some useful functions that either you or any web developers need to know for customising website.  Furthermore, these functions can make your website more responsive, more security and more cool. In addition, these function can save your money (without using paid plugin), save much time for coding and test. Therefore, I create a list of 20 cool customised functions that can support you to select the most essential FUNCTIONS that you really need for your website. These functions are compatible with most popular themes and most of Wordpress versions. Besides, I will update more functions in this post for easy reviewing. In addition, the table of content on the right sidebar will support you to navigate easily. Before implementing the process, you need to concentrate on some important steps. READ THIS CAREFULLY BEFORE YOU GO  Backup you website Separate each function below for testing before officially activating. You can use plugin snippets or other plugins or separated it in function.php. During testing, if it conflicts, incompatible or make errors on your theme, you can remove it, safely. You just copy and paste PHP code to snippet plugin and activate it. It begins with " " I already tested all codes below, It works like a charm. So if you have question or error code that need for support. You can leave your comment below. I will give you feedback asap. It could be including "How to use" and "CSS" parts. " " shows you how to display the function's result in html markup or insert it directly into posts. Therefore, you do not need to copy it into function.php or code snippet. Besides, " " supports you to decorate Html code block. Code snippets compatibility: Wordpress version > 4.6 PHP ~ 7.xx
