What I normally have is a Connection class that pages will require in order to establish a connection. Something along the lines of:

class Connection    {
    public $dbConnection = null;
    public $isConnectionActive = false;
    private $dbServer = null;

    private $dbPassword = null;
}

This class handles opening and closing of the connection on any pages.
