run code in 300+ PHP versions simultaneously
<?php $a = array(); $arrayKey = '[0][1]'; $a[0][1] = "two levels deep"; echo ${'a'.$arrayKey} = "two levels deep";

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).
