global class

[Marino]

Currently I have a situation in which I had a class using an other class

//given 2 classes classa and classb
$nr = 1;
$a = new classa($nr);
$b= new classb($a)
//Now $nr is also known in $b
//But when I do this
$b->a->addtonr(1);
//$nr in $b is now increased by 1
//but $nr in $a is still 1

My question is how to make $a a global class so I $nr in $a is also increased

--Update: Global does not work. I managed to make my classes global, however this is not the solution. There are still 2 different instances of the variable $nr ($a->nr).
How to link them!?

normally you give a copy of the var to the function i suppose using

function b(&$a)
{
$this->a = &$a;
}

as constructor of class b will pass a reference which will solve your problem

there's no need of making the class global

Yes indeed. after head breakings and other stuff i found it out myself too. But thanks anyway!
