OO wonders

[odel]

hi

I'm using the model view controller to develop an application

each class of the controller package (FileController , ArticleControll er)
has the main controller (Controller) as a member.

The controller has the DbAccess object as a member

which means that when I need to call the a method of the DbAccess from a
controller class, it looks like that :

$this->oController->oDbAccess->fetchArray(... ) for example.

Now my question is, is that a problem for the performance of the
application. Should I declare the Controller and the DbAccess as GLOBAL
variables or doesn't it matter ? I prefer to avoid using GLOBAL, I think
it's ugly, but would be happy to use it if it's good for the speed of
the code.

Since php is not fully object oriented, I'm sometimes wondering if
designing it Java or Python style is not a bad idea.

Any comment appreciated !

thanks

You can use a singleton object instead of a global.

something like:

class mediator {

function &project_instan ce(){

static $instance;

if (!isset($instan ce)){
$instance = new project();
}

return $instance;
}
}

$x =& mediator::proje ct_instance();

This will give you always the same object, without using global.
