run code in 300+ PHP versions simultaneously
<?php if (!function_exists('foo')) { function foo() { echo bar();} } if (!function_exists('bar')) { function bar() { return 'bar';} } foo(); bar();

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).
