Bugs & Features
<?php $o1 = new stdclass($_GLOBALS['a']=8); var_dump($_GLOBALS['a']); // Notice: Undefined variable: a var_dump($o1); $o2 = new Datetime($b='now'); var_dump($b); // string "now"

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.
