Question: what the hell are you talking about?

No, it's not. Check this out:

Code:

class Test
{
	protected $x = 2;
	
	public static function first_method()
	{
		return $this->x;
	}
	
	public static function second_method()
	{
		return 'cant use $this in static methods';
	}
	
	private static function third_method()
	{
		return 'you cant call me na na na na na';
	}
}

Test::first_method(); // Fatal error: Using $this when not in object context
Test::second_method(); // the right call
Test::third_method(); // Fatal error: Call to private method Test::third_method() from context ''

So you see, you can't just 'grab' any method/property from a class.

Tlc: it's pretty simple. Do you need an instance of a class to authenticate a user, for example? Then don't use static methods. Static methods are made for defining behavior, not functionality.
