Still running a huge share of the web

PHP Compiler Online — Run PHP Code in Your Browser

PHP was built specifically for the web, and despite the jokes, it still powers a massive share of it — WordPress alone accounts for a large fraction of all websites. It's quick to write and quick to deploy for server-side scripting.

<?php

function main() {
    echo "Hello, world!\n";
}

main();

What people use PHP here for

• Testing a small PHP function or string-manipulation snippet
• Following a PHP tutorial without a local server (Apache/nginx) setup
• Checking how a specific PHP built-in function behaves

No installs, no signup

Code you write here runs on a real, self-hosted Judge0 execution backend — actual PHP compiler or interpreter output, not a simulation. A real PHP interpreter runs your code directly — no need to stand up Apache or nginx just to test a function. See the full list of supported languages or read more about how AnyCompiler works.
