run code in 300+ PHP versions simultaneously
<?php namespace A { class A{ const Z = 9; } } namespace B { class B { const Z = 8; } } namespace { use B as BB; const Z = 7; echo BB::Z; }

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).
