run code in 300+ PHP versions simultaneously
<?php $array1 = [8,11,5,6,7]; $array2 = [1,2,3]; $arrays = [$array1, $array2]; function array_cartesian($arrays) { if(count($arrays) == 0) { return array(array()); } $a = array_shift($arrays); $c = array_cartesian($arrays); $r = []; foreach($a as $v) { foreach($c as $p) { $r[] = array_merge(array($v), $p); } } return $r; } print_r(array_cartesian($arrays));

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).
