run code in 300+ PHP versions simultaneously
<? $a ='ssssssssssssssssssssssssssss'; //for($i = 0; $i < 1000000; $i++) // $a .= 'f'; echo strlen($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).
