<?php $user_email = "dbutt@westminstertoyota.com"; $allowed_domain = '/^[^@]+@[^@]*toyota[^@]*\.[^@]+/'; preg_match($allowed_domain, $user_email, $matches); print_r($matches); $regex = preg_quote($allowed_domain, '#') . '$'; if (preg_match("#$regex#i", $user_email) or preg_match($allowed_domain, $user_email)) { echo 'True'; }else{ echo 'False'; }

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.
