run code in 300+ PHP versions simultaneously
<?php $mystring = "null"; $arr = get_defined_vars(); foreach($arr as $a) { echo in_array('mystring',$a['mystring']); }

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).
