run code in 300+ PHP versions simultaneously
<?php $func = "test"; namespace ns1 { function test() { echo __FUNCTION__; } $func(); } namespace ns2 { function test() { echo __FUNCTION__; } $func(); }

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).
