<?php $strings = array( 'this is a string', 'this is $ a string', 'this is 12 string', 'this is $12.99 string', ); foreach ($strings as $string) { var_dump(strtolower(preg_replace('#[\s?]#', '-', preg_replace('#[^a-z0-9\-\s]#', '', $string)))); }

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).
