run code in 300+ PHP versions simultaneously
<?php function a() { b(array(1, 7, 4)); } function b($b) { c(); } function c() { debug_print_backtrace(); } a();

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).
