A new way to make singleton in PHP?

php_singleton_test.php

<?php

/**
 * @author: Garith
 */
class Singleton{
	protected static $instance = null;
	
	public static function load(){
		if(self::$instance === null){
			self::$instance = new self();
		}	
	}
	// The old fashioned and dumb way of doing (oh my) Singleton in PHP
	private function __construct(){
		// =D
	}
			
}

Singleton::load();

// $wrong = new Singleton(); //Fatal error too. Oh my. =D
