run code in 300+ PHP versions simultaneously
<?php $foo = array(); $foo['foo'] = 'hello'; // Wrong key order // $foo['foo']['bar'] = 'world'; // Right key order $foo['bar']['foo'] = 'world'; print_r($foo);

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).
