run code in 300+ PHP versions simultaneously
<?php $arr = array(); $arr[] = 'something'; $arr[] = 'some more'; array_splice($arr, 0, 2); $arr[] = 'should be index zero'; print_r($arr);

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).
