run code in 200+ php & hhvm versions
Bugs & Features
<?php // Get the values "a", "b" from $arr = array('a' => 'foo', 'b' => 'bar', 'c' => 'car'); var_dump(array_intersect_key($arr, array_flip(array('a', 'b')))); // returns array('array('a' => 'foo', 'b' => '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.
