<?php preg_match_all( '/\[([\w]*?)\:([\w\W\s]*?)\]/' , '[email:optin|<u>Optin</u>]' , $matches); echo $class = "Frontburner_Tag_" . ucfirst( trim( strtolower( $matches[1][0] ) ) ) . "\n"; $values = explode( "|" , $matches[2][0] ); $tag = $values[0]; echo $tag . "\n"; echo "return" . ucfirst( trim( strtolower( $this->tag ) ) );

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).
