run code in 200+ php & hhvm versions
Bugs & Features
<?php $a = assert(true); $b = assert(false); $c = assert('true'); $d = assert('false'); var_dump($a, $b, $c, $d);

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.
