<?php $a = array ( 0 => '%unaware%', 1 => '', 2 => '%', 3 => '', 4 => '', 5 => 'unaware', 6 => '', ); list(, , $tag, $atts, $cite, $content, $end) = $a; var_dump($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).
