run code in 200+ php & hhvm versions
Bugs & Features
<?php function f ($name, $vars) { var_dump($vars); return $name; } trait A { function bar() { var_dump(get_class(), get_class(null), get_class(self), get_class(${f('this', get_defined_vars())})); } } class B { use A; } $f = new B; $f->bar();

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.
