run code in 300+ PHP versions simultaneously
<?php session_start(); $_SESSION['foo'] = 42; print_r($_SESSION); $_SESSION = array(); session_destroy(); var_dump(array() === $_SESSION);

Here you find the average performance (time & memory) of each version. A grayed out version indicates it didn't complete successfully (based on exit-code).
