<?php $foo = new SplFixedArray(2); $foo[0] = 'bar1'; $foo[1] = 'bar2'; var_dump(isset($foo[0]) ? $foo[0] : null); var_dump(isset($foo[1]) ? $foo[1] : null); var_dump(isset($foo[2]) ? $foo[2] : null);

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).
