run code in 300+ PHP versions simultaneously
<?php $A = array(3,4); $B = array(10, 20); foreach ($A as $k => &$i) $i++; foreach ($B as $k => &$i) $i++; var_dump($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).
