run code in 300+ PHP versions simultaneously
<?php $timestart = microtime( true ); $string = "This is an?example string"; for( $i=0; $i<=1000; $i++ ) { $result = time(); } $timeend = microtime( true ); $timetotal = $timeend - $timestart; $r = number_format( $timetotal, 5 ); echo $r; echo $result;

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).
