run code in 200+ php & hhvm versions

<?php var_dump( (object) array( "\0bar" => 1, "\0\0baz" => 2, ) );

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.
