Re: HELP ! ! ! something simple . . . :D

class A
{
public function methodA(){
//some useful code
}
class B
{
private A $instanceOfA; //but I am really not sure if this one's works

public __construct() {
$instanceOfA=new A();
}
public function methodB(){
$this->instanceOfA->methodA();
}
}
}
Anyway this is legal in terms of OO-Programming and also a well used
method for composing classes. I tried this out in PHP but it doesn't
seem to work. Obviously you'll have to create the instance within the
function/method you want to use it. Like:

What you really wanted to do in the constructor of B was the following:

public __construct() {
$this->instanceOfA = new A();
}

Because with $instanceOfA you create a local (in that function) variable...
