<?php class foo { public function something() { echo __CLASS__; // foo var_dump($this); } } class foo_bar extends foo { public function something() { echo __CLASS__; // foo_bar var_dump($this); } } class foo_bar_baz extends foo_bar { public function something() { echo __CLASS__; // foo_bar_baz var_dump($this); } public function call() { echo self::something(); // self echo parent::something(); // parent echo foo::something(); // grandparent } } error_reporting(-1); $obj = new foo_bar_baz(); $obj->call(); // Output similar to: // foo_bar_baz // object(foo_bar_baz)[1] // foo_bar // object(foo_bar_baz)[1] // foo // object(foo_bar_baz)[1] ?>

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).
