Run PHP online in your browser

A free online PHP playground and code runner. Write PHP in your browser, hit Run, and the code executes on PHP 8.3 in seconds. No Apache, no nginx, no XAMPP or MAMP to set up first.

The editor is built on the same engine as VS Code, so PHP syntax highlighting, autocompletion, and error squiggles all work. Code runs on PHP 8.3 CLI with OPcache plus common extensions — mbstring, curl, xml, simplexml, dom, tokenizer, openssl, zip, fileinfo, and json — and Composer on the path. Good for testing a regex, serializing JSON, or exploring match expressions.

What makes this PHP playground useful

Instant PHP execution — write code, press Run, and see output from the PHP 8.3 CLI in seconds, no Apache, nginx, XAMPP, or MAMP needed.
Full PHP syntax highlighting, autocompletion, and clear error messages with line numbers, powered by the same editor engine as VS Code.
Stdin input is supported. fgets(STDIN), file_get_contents('php://stdin'), and STDIN stream reads all work from the playground's input box, so CLI-style PHP scripts run end-to-end. No Apache, XAMPP, or MAMP on your end.
PHP 8.3 with mbstring, curl, xml, simplexml, dom, openssl, zip, fileinfo, OPcache, and Composer on the path — test modern PHP features like enums, readonly properties, match expressions, and typed properties.

What you can build in the PHP playground

Array functions: array_map, array_filter, array_reduce, and associative-array transformations you can test one line at a time.
String helpers and regex (preg_match, preg_replace), plus JSON encode/decode: the day-to-day PHP idioms you'll use in any backend.
Quick PHP experiments: test a match expression, try an enum, verify a typed property, or confirm how the spread operator works in arrays.

Online PHP compiler FAQ

Is the online PHP compiler free?

Yes, the PHP playground is free to use. No sign-up, no PHP install, and no Apache or XAMPP setup required — open the page and run code on PHP 8.3.

Do I need PHP, Apache, or XAMPP installed?

No install needed. You don't need PHP, Apache, nginx, XAMPP, or MAMP on your machine. The online PHP runner executes your code on PHP 8.3 CLI and returns the output in seconds.

Does the PHP playground work on mobile and Chromebooks?

Yes. The PHP playground runs in any modern browser, on desktop, tablet or mobile. Good for testing PHP from a Chromebook, iPad, or school computer where you can't install a LAMP stack.

Does the PHP playground support fgets(STDIN) and stdin?

Yes. fgets(STDIN), file_get_contents('php://stdin'), and reading from the STDIN stream all behave the same way they would when you run php script.php at the terminal and type input. Useful for CLI-style PHP scripts and practice exercises.

How do I learn PHP after trying the playground?

Edit the sample PHP code, press Run, and iterate. When you want something more structured, Coddy's interactive PHP course covers arrays, strings, classes, namespaces, and modern PHP 8 features with hands-on exercises.
