Public, Global, Bah!!

[bpat1434]

Okay, so I'm doing a small re-code to a site I operate. I am moving to OOP, and with that, I am having issues. I have it set up so that I have all my functions in one file (inc.functions.php). I have a database connector class (class.database.php) which utilizes a function if there is an error. Unfortunately, it seems that scope is an issue in this.

So I researched the "::" and public items on php.net. Still, not quite understanding what's going on. I declare my funcitons as 'function name(){}'. If I go to utilize a function, it tells me it is an invalid function, but the file is included. Any ideas here? Not too sure where to look, or how to go about debugging it. I know it's something simple, but i can't seem to get it.

    if(!$this->conn)

        $er['error'] = throw_error('mySQL Connection Error', mysql_errno(), mysql_error());
        return $er;
    }
    else
    {

            return $er;
