run code in 200+ php & hhvm versions
Bugs & Features
<?php $i=2; const BIT_1 = 0; // compile time: heeds lexical grammar rules define('BIT_'.$i,1); // runtime: more flexibility in naming echo BIT_1,"\n"; echo BIT_2,"\n";

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).
Note: hhvm uses a JIT which only kicks in after a few runs. Since we run scripts only once, hhvm always runs slower.
