<?php function event($name,$cb = null){ static $e = []; if ( is_callable($cb) ){ empty( $e[$name] ) ? $e[$name] = [$cb] : $e[$name][] = $cb; } elseif ( false === empty($e[$name]) ) { $a = is_array($cb) ? $cb : []; foreach ($e[$name] as $eh) call_user_func_array($eh,$a); } }

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).
