<?php if (class_exists('PDO')) { $ref = new ReflectionClass('PDO'); foreach ($ref->getConstants() as $key => $value) { printf("%s => %s\n", $key, $value); } }

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).
