run code in 300+ PHP versions simultaneously
<?php $a = array('a', 'b', 'c'); /*foreach($a as $k=>$v){ if($k==1) unset($a[$k]); echo $k.' => '.$v.' ('.$a[$k].')'.PHP_EOL; }*/ for($k=0; $k<count($a); $k++){ if($k==1) unset($a[$k]); echo $k.' => '.$v.' ('.$a[$k].')'.PHP_EOL; } print_r($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).
