run code in 300+ PHP versions simultaneously
<?php $times = 10000; $var = null; $var = new stdClass(); $time1 = microtime(true); for ($i = 0; $i <= $times; $i++) { if (!$var) {} } $time1 = microtime(true) - $time1; //echo "Time using '!': $time1\n"; $time2 = microtime(true); for ($i = 0; $i <= $times; $i++) { if ($var === null) {} } $time2 = microtime(true) - $time2; //echo "Time using '===': $time2\n"; if ($time1 > $time2) echo "'===' was faster by {($time1-$time2)/$time2}%"; else echo "'!' was faster by {($time2-$time1)/$time1}%";

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).
