Hello!

I'm a PHP newbie, but I've been busy writing much OO-Code over the last
years.
I had an idea solving this problem using the following scheme:

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:

class B
{
//....
public function methodB(){
$instanceOfA=new A();
$instanceOfA->methodA();
}
}

Well I ran a test with that and it worked. It's not that elegant but I
think it makes sense...
