run code in 300+ PHP versions simultaneously
<?php gc_enable(); class test { private static $count = 0; public function __construct() { self::$count++; } } $i = 0; while($i < 500) { $test = new test(); unset($test); gc_collect_cycles(); echo number_format(memory_get_usage()) . " B \n"; $i++; }

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).
