<?php $string = '{"smartling": {"files": ["Hello World"] }}'; $result = json_decode($string); // Result: object(stdClass)#1 (2) { ["foo"]=> string(3) "bar" ["cool"]=> string(4) "attr" } var_dump($result);

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).
