<?php $string = "blah 2015 yar"; $pos = strpos($string, "20"); $year = substr($string, $pos, 4); echo $year . "<br />\n"; $end_year = "12/31/" . $year; $end_time = new DateTime($end_year); $start_time = new DateTime(); $diff = $end_time->date ->diff($start_time->date); var_dump($diff); ?>

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).
