run code in 300+ PHP versions simultaneously
<?php namespace A\B { class C { function p() { echo 'A\B\C'; } } } namespace M\N { use A\B\C as C2; class C { function p() { echo 'M\N\C'; } } class X extends C { } } namespace { $x = new M\N\X(); $x->p(); }

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).
