Run PHP online in your browser

This is a free online PHP playground and code runner. Write PHP code directly in your browser, hit Run, and execute on PHP 8.3 in seconds — no Apache, no nginx, no XAMPP or MAMP required. It's the fastest way to test an array function, verify a string helper, or try a modern PHP feature like enums or readonly properties.

Under the hood, the editor uses the same engine as VS Code (PHP syntax highlighting, autocompletion, error squiggles), and your 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. Whether you're testing a regex, serializing JSON, or exploring match expressions, this online PHP compiler goes from idea to output in seconds.

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 — the same editor engine that powers VS Code.
  • Stdin input 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 install — no Apache, XAMPP, or MAMP.
  • 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 spread-operator in arrays works.

Online PHP compiler FAQ

Is the online PHP compiler free?
Yes. The PHP playground is completely free — no sign-up, no PHP install, 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 on any modern browser — desktop, tablet, or mobile. Great 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. The playground has a stdin input box — fgets(STDIN), file_get_contents('php://stdin'), and reading from the STDIN stream all work 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 structured practice, Coddy's interactive PHP course covers arrays, strings, classes, namespaces, and modern PHP 8 features with hands-on exercises.
