run code in 300+ PHP versions simultaneously
<?php class test { $a; function a() { echo $this->a; } function __destruct() { echo 'b'; } } $a = ['test','a']; $a();

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).
