run code in 200+ php & hhvm versions
Bugs & Features
<?php $a = 'a'; $b = 'b'; echo sqrt(2); echo (isset ($a) && isset ($b) && !is_numeric (($a * $b) . '') ) && (($a * $b) != INF) ? 1 : 0; ?>

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.
