Get started freeFrequently Asked Questions
What PHP version does this online compiler use?
This PHP compiler runs PHP 8.2, providing the latest language features including enums, readonly properties, named arguments, and significant performance improvements. Write modern PHP code with contemporary syntax.
Can I use PHP with HTML and databases?
This online PHP compiler focuses on server-side PHP logic execution. HTML output works (echo statements), but database connections and $_POST/$_GET superglobals have limitations. Perfect for testing pure PHP logic and algorithms.
What PHP functions are available?
Access to all PHP built-in functions: string operations, array manipulation, date/time, math, file handling functions, and more. Object-oriented features like classes, interfaces, and traits are fully supported.
Can I test WordPress or Laravel code?
This PHP online compiler runs pure PHP without frameworks or CMS. Perfect for testing PHP logic that would go into WordPress plugins, Laravel controllers, or any PHP application. Learn PHP fundamentals before framework specialization.
Is this good for PHP interview preparation?
Excellent for interviews! Test PHP algorithms, object-oriented design problems, and language-specific challenges. Practice array manipulation, string processing, and modern PHP features. Share solutions via URL for interview discussions.
How do I debug PHP code here?
Use var_dump(), print_r(), or echo to debug PHP variables and program flow. All output appears in console. Error messages show line numbers and error types for effective PHP debugging.
What happens with infinite loops in PHP?
PHP code runs for up to 30 seconds before automatic timeout. Infinite loops are terminated to prevent system hang. This safety measure ensures fair usage while providing time for complex PHP execution.
Can I use Composer packages?
This online PHP compiler doesn't support Composer or external packages. Focus on PHP standard library and core language features. Perfect for learning PHP fundamentals without dependency management complexity.
