run code in 300+ PHP versions simultaneously
<?php function a() { return; } function b() { return false; } $start = microtime(true); for ($i = 0; $i<9999; $i++) { a(); } $end = microtime(true); echo "A :".($end-$start)."\n"; $start = microtime(true); for ($i = 0; $i<9999; $i++) { b(); } $end = microtime(true); echo "B :".($end-$start)."\n";

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).
