run code in 200+ php & hhvm versions
Bugs & Features
<?php $null = null; $x = array( $null => 'null', 0 => 0, ); var_dump($x);

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.
