<?php $o = new stdClass; $o->text = "ans1"; $o2 = new stdClass; $o2->text = "ans2"; $o3 = new stdClass; $o3->text = "ans3"; $arr = [$o, $o2, $o3]; var_dump($arr); $nu = array_map($arr,callback); function callback($e) { return $e->text; } var_dump($nu);

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.
