Faster PHP? Kick off getters and setters.

In PHP getters and setters sucks on performance.

	<?php
	class dog {
	public $name = '';
	public function setName($name) {
	$this->name = $name;
	}
	public function getName() {
	return $this->name;
	}
	}
	class cat {
	protected $name = '';
	public function __set($name, $value) {
	$this->$name = $value;
	}
	public function __get($name) {
	return $this->$name;
	}
	}
	class worm implements ArrayAccess {
	public $name = '';
	public function offsetUnset($name) {}
	public function offsetExists($name) {}
	public function offsetSet($name, $value) {
	$this->$name = $value;
	}
	public function offsetGet($name) {
	return $this->$name;
	}
	}
	function test_getters_setters() {
	echo __FUNCTION__ . ":\t" ;
	$Class = new dog();
	$s = 0;
	for ($x=0; $x<10; $x++) {
	$t = microtime(true);
	for ($i=0; $i<1000000; $i++) {
	$Class->setName("rover");
	$n = $Class->getName();
	}
	$s += microtime(true) - $t;
	}
	echo ($s / $x) . "\n";
	}
	function test_public_properties() {
	echo __FUNCTION__ . ":\t" ;
	$Class = new dog();
	$s = 0;
	for ($x=0; $x<10; $x++) {
	$t = microtime(true);
	for ($i=0; $i<1000000; $i++) {
	$Class->name = "Rover";
	$n = $Class->name;
	}
	$s += microtime(true) - $t;
	}
	echo ($s / $x) . "\n";
	}
	function test_magic_methods() {
	echo __FUNCTION__ . ":\t" ;
	$Class = new cat();
	$s = 0;
	for ($x=0; $x<10; $x++) {
	$t = microtime(true);
	for ($i=0; $i<1000000; $i++) {

	$s += microtime(true) - $t;
	}
	echo ($s / $x) . "\n";
	}
	function test_array_access() {
	echo __FUNCTION__ . ":\t" ;
	$Class = new worm();
	$s = 0;
	for ($x=0; $x<10; $x++) {
	$t = microtime(true);
	for ($i=0; $i<1000000; $i++) {
	$Class['name'] = "Rover";
	$n = $Class['name'];
	}
	$s += microtime(true) - $t;
	}
	echo ($s / $x) . "\n";
	}
	test_getters_setters();
	test_public_properties();

WTF? How many getters/setters You use in your project per request?
