run code in 300+ PHP versions simultaneously
<?php $a = array('bar'); $xyz = 'foo'; array_splice($a, 0, 1, array(&$xyz)); $xyz = 'baz'; var_dump($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).
