How to Run PHP Online with Our Compiler

Our PHP online compiler provides a complete development environment directly in your browser. Write PHP code in the editor, click the Run button, and see instant results in the output panel. The compiler supports multiple PHP versions, allowing you to test code compatibility across PHP 8.3, 8.2, 8.1, 8.0, and 7.4.

Key Features of PHP Online Compiler

The compiler is built for speed and ease of use. Code execution happens in milliseconds using WebAssembly technology, ensuring your scripts run as fast as locally installed PHP. The interface includes syntax highlighting, adjustable font sizes, and theme options for comfortable coding sessions.

Privacy is paramount. Your code runs entirely in your browser without being sent to external servers unless you explicitly create a shareable link. This makes our compiler perfect for working with proprietary code, sensitive algorithms, or simply maintaining your privacy while learning PHP.

PHP Version Support

Testing code across different PHP versions is essential for ensuring compatibility. Our compiler includes support for PHP 8.3 (latest stable), PHP 8.2, PHP 8.1, PHP 8.0, and PHP 7.4. Switch between versions using the dropdown selector to verify your code works correctly across different environments.

Each PHP version includes its respective feature set, allowing you to test new language features like named arguments, attributes, union types, match expressions, and more. This is particularly valuable when upgrading legacy codebases or learning about version-specific improvements.

Common Use Cases

Learning PHP: Experiment with language features, try examples from tutorials, and test your understanding with instant feedback.
Quick Testing: Verify algorithm logic, test regular expressions, parse JSON data, or format dates without setting up a local environment.
Code Sharing: Create shareable links to code snippets for collaboration, code reviews, or asking questions on forums and Stack Overflow.
Interview Preparation: Practice coding problems in a clean environment similar to many technical interview platforms.
Teaching: Demonstrate PHP concepts with live code examples that students can modify and run themselves.

Error Handling and Debugging

When your PHP code encounters errors, the compiler displays clear error messages with line numbers and descriptions in the output panel. This helps you quickly identify and fix issues. Execution time is displayed for each run, helping you understand performance characteristics of different approaches.

PHP Online Compiler FAQs

What is a PHP online compiler?

A PHP online compiler is a web-based tool that allows you to write, compile, and execute PHP code directly in your browser without installing PHP on your computer. It provides an instant development environment accessible from any device.

How accurate is the online compiler compared to real PHP?

Our compiler uses the same PHP interpreter that powers millions of websites worldwide, compiled to WebAssembly for browser execution. The behavior matches native PHP installations, ensuring accurate results for standard PHP code.

Can I use PHP frameworks like Laravel or Symfony?

The online compiler is designed for standalone PHP scripts and doesn't support full frameworks that require server infrastructure, databases, or complex dependencies. It's perfect for testing language features, algorithms, and built-in functions.

Are there execution time limits?

Scripts are limited to a reasonable execution time to prevent infinite loops from freezing your browser. This limit is sufficient for testing typical code snippets, algorithms, and learning exercises.

Can I save my code permanently?

Use the Share button to create a permanent link to your code. The shareable URL includes your complete code and can be accessed anytime or shared with others.

Do keyboard shortcuts work in the editor?

Yes! Press Ctrl+Enter (or Cmd+Enter on Mac) to run your code, Ctrl+S to create a share link, and Tab to indent code. The editor supports standard text editing shortcuts.
