foreign object within another class

Anon

I'm using two objects which are object of 2 different classes: $obj1 (of class1) and $obj2 (of class2)

class class1 {
var $var1;
}

class class2 {
function shout() {
echo $obj1->var1;
}
}

$obj1 = new class1;
$obj1->var1 = "hello world";

the problem is that I need to access the variable of obj1 from almost all functions within class2 (there are more functions than in my example above).

to make this work I must set $obj1 global:

function shout() {
global $obj1;
echo $obj1->var1;
}

Is it possible to set $obj1 global for all functions within class2 or do I have to set it global within each function of class2 again and again? any other hints?

Thanks

in the constructor for obj2, do
global obj1;
$this->someduplicatevariablecausedbypoorclassdesign = &$obj1->var1;

That way you can access the obj 1 variable anywhere in 2 by referencing the reference on obj2 object.

thanks tom,
but what if my obj1 has not only 1 but let's say 100 variables, that's a lot of code...

is there another solution?

Maybe you didn't read into my previous post enough. You need to redesign your classes man.

Sorry Tom,

classes are someting rather new for me. I don't how, how to do perfect class design. Should I merge the two classes, so that I have the same object for all the functions? (Acutally I would like to keep them seperate, because they do rather different things).
