Online PHP Playground

Runs on PHP 7.4.1 · Free · No signup required

A free online PHP playground for backend engineers who want to test something without spinning up a local stack. Write PHP, run it, and get output in seconds — no XAMPP, no Docker, no signup. It is the fastest way to check the behaviour of a string function you are unsure about, confirm how an array sorts, or sanity-check a snippet before pasting it into a Laravel or Symfony project. Code executes server-side against a real PHP interpreter, so the output reflects genuine runtime behaviour rather than a simulation. Standard input is supported, so scripts that read from stdin work as expected. If you are moving from writing PHP snippets to building real backends with it, the playground sits alongside our backend projects and engineering courses.
