Static methods in PHP

Question

Why in PHP you can access static method via instance of some class but not only via type name?

UPDATE: I\'m .net developer but i work with php developers too. Recent

Sometimes, it is useful if we can access methods and properties in the context of a class rather than an object. To do this, you can use static keyword. So we can access static method using class name along with scope resolution .

class User
{
    public static $name = 'john';

    public static function display()
    {
        return self::$name;
    }
}

echo User::display();

Look here we declared a static method in our User class . So if we declare a static method then we can access there using just class name . No need to create object to access there . Hope you will understand all the procedure .

Note : This is actually the main difference with a normal method : $this is not available in such methods.
