run code in 200+ php & hhvm versions
Bugs & Features
<?php $a = array("1"=>"A", 1 => "B", "C", 3=>"D"); echo count($a); var_dump($a);

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.
