run code in 300+ PHP versions simultaneously
<?php function foo() { for ($i = 0; $i < 10 ; $i++) { yield $i; } } echo count(foo()); echo foo()

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).
