<?php abstract class AbstractFoo { public $bar; final public function __construct() { $this->bar = static::BAR; } } class FooBar extends AbstractFoo { const BAR = 'foobar'; } class Foo extends AbstractFoo { //const BAR = 'foobar'; } $fooBar = new FooBar(); var_dump($fooBar->bar); $foo = new Foo(); var_dump($foo->bar);

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).
