run code in 300+ PHP versions simultaneously
<?php $all = array(array("class"=>array(array("peter","15","male"),array("mary","24","female"),array("jason","22","male")))); print_r($all); function merge($prev,$now){ $i=0; return array_merge($prev,$now['class'][$i]); $i++; } $cc = array_reduce($all,"merge",array()); print_r($cc);

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).
