How: call obj methods out of other objects

[jbegham]

Hi group,

my question is:
If you have an object A with a method A1 and a second object B where you overgive object A within the B-Constructor: how can you call a object A method out of object B?

e.g.

class A {
  function A1() { }
}

class B {
  var $aktObjA;

  function B ($objectA_in) {
    $this->aktObjA = $objectA_in;
  }

  function concatBA () {
  ????? $myTest = $this->aktObjA->A1();
  }

}

This code above did not result the A1-Value.

Isn't this syntax possible in PHP?

$this->var_from_obj_b->method_from_obj_a()

where var_from_obj_b is a type of Obj. A

Hope anybody of you has an idea.

TIA
John

There's nothing wrong with your code.
Calling a method like you described is possible in PHP.
Did you make the appropriate instantiation of both classes like this:

$a = new A();
$b = new B($a);
$b->concatBA();

Are you getting any error messages or just inconsistent values?

hi boogiemacs,

after reading your reply, I just went back to my coding to check it again. I get trapped by the $-sign I unfortunatly placed ($this->$obj😎. After removing this buggy character, everything works find.

Greets,
