<?php $a = array(); $a['lol'] = 'fuu' or die; print_r($a); $a = array('lol' => 'fuu' or die); print_r($a); $a = array('lol' => 'fuu' and 'fee'); print_r($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.
