run code in 300+ PHP versions simultaneously
<?php $arr = array( array("item_data"=>array(1,2,3)), array("item_data"=>array(4,5,6)), array("item_data"=>array(7,8,9)) ); var_dump($arr); function merge($prev, $now) { return array_merge($prev, $now['item_data']); } $res = array_reduce($arr, "merge", array()); print_r($res);

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).
