Using a function from another class

Question

I'm just starting with OOP (shame on me), so be gentle with me.

I have an ErrorHandler class that calls a function from my main Application class to include an error page. So I'm using Application::status_page( $type ); in a function in the ErrorHandler class.

This is how the status_page function looks like (it's a function to include all kinds of custom messages):

public function status_page( $page )
{
    // Include the status page that has been set in the routes
    include( STATUS_PAGE_DIR . $this->status_pages[$page] . '.html' );
}

I'm now getting an Undefined property: ErrorHandler::$status_pages which makes total sence to me. But what is the best way to solve this? Maybe let the ErrorHandler class extend the main Application class?

I hope I was clear and thanks in advance for answering.

might consider composition over inheritance,btw did ur ErrorHandler class have $status_page property? — slier

Yes $status_pages has been set. So you mean I just initiate all my other classes like ErrorHandler in the construct of my main Application Class? So I don't have to use static functions, right? — Jesse

$status_pages must be defined in the header of the class

also, you must declare the function as

public static function status_page($page)

if you want to use it like that.

If you dont' want to to use it static, you'll have to create an instance of the class with $var = new ClassName();

When I make it static I get the error "Using $this when not in object context". Creating a new instance is not an option I'm afraid (it will reset $status_pages).
