run code in 300+ PHP versions simultaneously
<?php namespace bar { $someVar = null; } namespace foo { function bar() { global $someVar; $someVar = 'Testing'; } } namespace { \foo\bar(); echo $someVar; }

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).
