Why hasn't anyone made a true PDF competitor?

By a PDF competitor, I mean a file format which has the same goals and non-goals as PDF does (or, at least, originally did). Here's how I see PDF's main goals:

* Document format

* Text-first

* Unambiguous visual representation (embedded fonts, per-glyph encoding)

* Embedded images

The most important non-goal is being editable. PDFs should be the final version of a document. Of course, Adobe has changed course on this and will now let you edit PDFs in various ways with generally much frustration. They needed to make forms as a place where things could be edited without much pain. This brings us to PDF's shortcomings:

* Complexity. PDF is not a straightforward format. Even with a good GUI, you can't dive into a PDF and figure out what's going on without some solid guidance. This makes it harder to build tools that work with PDFs. I don't think I've heard of anyone who's had to build something that digs deep into PDF's structure and enjoyed the experience. It also makes it easier for bugs to lurk beneath the surface, which is related to;

* Bloat. PDF has so many different things piled on that may or may not work together and may or may not work at all. You want interactivity? We can give you hyperlinks and popups. You want more than popups? You want a whole game in your PDF? Sure, it's possible, because they decided to embed JavaScript in there. You want to digitally sign your PDF so nobody can change it? Great! Except they can change certain parts that Adobe didn't think to include in the signature. Whoops.

* Inconsistency. Embedding fonts is great because you don't have to rely on certain fonts being installed on the viewer's computer. So, naturally, Adobe made sure that 14 fonts have to be installed on the viewer's computer. If not, it'll look wrong, which breaks goal 3. Also, there's whatever Scribd is doing, which I suspect is somehow related but who knows.

With all that said it seems like it should be possible to make a finalized document format with a stripped-down feature set, good cryptography (maybe by default! there's no reason not to sign such a file), and an unambiguous, pixel-perfect visual representation. Maybe something XML-based, like ODF and other document formats. Or maybe it already exists, in which case please yell at me in the comments.

What Is PHP

What Is PHP, and why is It Still Essential in Web Development

PHP (short for Hypertext Preprocessor) is one of the most widely used scripting languages for building websites and web applications. It’s open-source, free to use, and runs on the server, meaning it processes tasks before content reaches your browser. Whether you're logging in to a website, filling out a form, or browsing dynamic content, chances are PHP is working behind the scenes.

In this post, we’ll break down what PHP is, what it’s used for, and why it continues to be a key part of modern web development.

What Is PHP?

PHP is a server-side scripting language that runs on web servers like Apache or Nginx. It helps developers build dynamic websites, meaning the content can change based on user input or data from a database.

Instead of just showing static pages, PHP allows for things like:

Displaying personalized user dashboards

Submitting and processing forms

Handling logins and registrations

Connecting to databases and fetching content

Key Features of PHP:

Server-Side Execution: Code runs on the server and sends the result to the browser.

Database Friendly: Easily connects with databases like MySQL, PostgreSQL, or SQLite.

Form Handling: Collects and processes data from HTML forms.

Session Management: Tracks users across pages (great for logins and shopping carts).

Platform Independent: Works on Windows, macOS, Linux—pretty much anywhere.

Large Community & Resources: Tons of tutorials, tools, and frameworks like Laravel.

What Is PHP Used For?

PHP is used for building all kinds of websites—from small personal blogs to full-scale eCommerce platforms. Let’s look at the common ways developers use PHP:

1. Dynamic Website Content

PHP helps create websites that change depending on who is visiting or what they’re doing. Think of personalized greetings, product recommendations, or updating shopping cart totals without refreshing the page.

2. Working With Databases

Need to store user data, products, or blog posts? PHP connects smoothly with databases like MySQL to save and fetch information, making it easy to manage large websites.

3. Handling Forms

When users fill out a form—say, to sign up or contact you—PHP processes that data. It checks if everything’s filled out correctly and then stores or emails the info.

4. User Sessions

PHP helps websites remember who you are as you move between pages. This is essential for things like staying logged in or remembering items in your cart.

5. Security and Automation

PHP allows you to add basic security layers, like input validation, data encryption, and access control. It’s also used for sending emails, generating PDF invoices, or even auto-posting to social media.

Is PHP Frontend or Backend?

PHP is strictly a backend language. While it works alongside frontend tools like HTML, CSS, and JavaScript, PHP runs on the server. It handles all the logic behind the scenes—things like checking passwords, fetching data, or updating user info.

Why PHP Still Matters Today

Even with new languages and frameworks entering the scene, PHP remains highly relevant. It powers big names like Facebook (originally built on PHP), WordPress, and Wikipedia. Plus, frameworks like Laravel have modernized PHP, making development faster and cleaner.

In short, PHP is still a reliable, powerful choice—especially for developers building secure, data-driven websites.

Conclusion

PHP might not always be in the spotlight, but it's still the backbone of the web. It’s fast, flexible, and works well with almost anything. If you're planning to build a dynamic website or web application, learning PHP is a solid first step—and it’s not going anywhere anytime soon.

Prevent CSP Bypasses in Laravel: Secure Your Web App

In today’s web development landscape, ensuring application security is a top priority. One critical defense is a Content Security Policy (CSP), which helps protect against cross-site scripting (XSS) and code injection attacks. However, misconfigurations or vulnerabilities in Laravel applications can lead to CSP bypasses.

This article will explore common CSP bypass techniques in Laravel and how to prevent them with coding examples.

📌 What is a Content Security Policy (CSP)?

A Content Security Policy (CSP) is a security mechanism that restricts the sources from which a web page can load scripts, styles, images, and other content. It helps prevent XSS attacks by blocking malicious scripts.

Browsers enforce CSP by blocking any content that doesn’t match the specified rules. However, attackers have found ways to bypass weak or misconfigured policies.

⚠️ Common CSP Bypass Techniques in Laravel

Even with CSP enabled, attackers can exploit weaknesses to bypass restrictions. Here are some common methods:

1️⃣ JSONP Endpoint Exploitation

Problem: Some Laravel applications use JSONP (JSON with Padding) for cross-domain requests. Attackers can inject malicious scripts through unvalidated callback parameters.

Example: A Laravel application using a JSONP API:

<script src="https://trustedapi.com/data?callback=handleData"></script>

If the callback is not properly validated, an attacker can modify it:

<script src="https://trustedapi.com/data?callback=alert(1)"></script>

🚨 This results in JavaScript execution, bypassing CSP.

✅ Mitigation:

Avoid JSONP; use CORS (Cross-Origin Resource Sharing) instead.

Validate callback parameters to allow only safe functions.

2️⃣ PHP Output Buffering Issues

Laravel uses PHP output buffering, and improper handling can make CSP ineffective. If headers are sent after the response body, CSP won’t be enforced.

Example:

<?php // Vulnerable Code echo str_repeat('A', 5000); header("Content-Security-Policy: default-src 'self';"); ?>

Since CSP is set after content is sent, the browser ignores it.

✅ Mitigation:

Set CSP before sending any output.

Use Laravel’s built-in response handling.

3️⃣ Insecure File Uploads

If an attacker uploads malicious JavaScript files, CSP won’t stop them if stored in public directories.

Example:

An attacker uploads malicious.js and accesses:

https://yourapp.com/uploads/malicious.js

Now, the attacker can execute arbitrary scripts!

✅ Mitigation:

Restrict uploads to safe file types (JPG, PNG, PDF, etc.).

Store files in non-public directories.

Rename uploaded files to prevent execution.

🔒 Implementing a Secure CSP in Laravel

To properly enforce CSP in Laravel, use the Spatie CSP package.

📥 Install the package:

composer require spatie/laravel-csp

🔧 Configure CSP in Laravel:

Publish the config file:php artisan vendor:

publish --provider="Spatie\Csp\CspServiceProvider"

Modify config/csp.php:

<?php return [ 'policy' => App\Policies\CustomCspPolicy::class, ]; ?>

Now, create CustomCspPolicy.php:

<?php namespace App\Policies; use Spatie\Csp\Policies\Policy; use Spatie\Csp\Directive; class CustomCspPolicy extends Policy { public function configure() { $this ->addDirective(Directive::DEFAULT_SRC, "'self'") ->addDirective(Directive::SCRIPT_SRC, "'self' https://trusted.cdn.com") ->addDirective(Directive::STYLE_SRC, "'self' 'unsafe- inline'"); } } ?>

🎯 This enforces a strict CSP to protect against XSS and injection attacks.

🛡️ Scan Your Website for CSP Vulnerabilities

To ensure your website is secure, use our Free Website Security Scanner:
