<?php $fixed = SplFixedArray::fromArray(range(1, 3)); $fixed->undefined = 'undefined'; $serialized = serialize($fixed); $unserialized = unserialize($serialized); var_dump($unserialized); var_export($unserialized);

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).
