Why static in PHP 5 … Example

[emukidz]

can someone explain me the difference between those 2 classes? Why to use satic calls instead of an new object?\[code\]class User { protected $users = array();/** * Create new user * * @param string $name Username * @return array Users */public function create($name){ $this->users[] = $name; return $this->users;}}$u = new User();var_dump($u->create('TEST'));class User{ protected static $users = array();/** * Create new user * * @param string $name Username * @return array Users */public static function create($name){ self::$users[] = $name; return self::$users,}}$u = User::create('TEST');var_dump($u);\[/code\]
