run code in 300+ PHP versions simultaneously
<? namespace B { const TEST12 = 1; } namespace A { use const B\TEST1 as TEST1; define ( 'TEST1', 5 ); echo TEST1; } ?>

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).
