<?php class a { public $a = " test a! "; static public $b = " test b! "; public function __toString() { return '[class a]'; } } $a = new a(); $b = "a"; $line = 0; echo $line++, $$b; echo $line++, $$b->a; echo $line++, $$b->b; // echo $line++, $$b::b; // ERROR

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.
