<?php $string1 = 'Ricambi auto'; $string2 = 'Autoricambi'; echo similar_text($string1,$string2,$pecent); ?>

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.
