hi php people,

 

I am wondering will  if the code below will work when I call $C->getafoo() will I get foo;  I keep getting an error at this point  return $this->A->a(); saying  the method is not there

 

class A{
  public function a(){
    return "foo";
  }
}

class B {
  public $A;

  function __construct($A) {
    $this->A = $A;    

  } 

  public function geta(){
    return $this->A->a();
  }
}


class C extends B{
  public function getafoo(){
   return geta();
}

}
$C = new C(new A());

echo $C->getafoo();

You need to call internal class methods using the special $this var:

 

  public function getafoo(){
   return $this->geta();
}

Thanks for the reply.

 

Yes your right in the script I am testing I have got that but thanks for pointing it out I left it out of the example. What I am wonder can I do this $this->A->a(); in php?

Yes. Why don't you just try it?

[Adam]

Yup, as long as "A" is an object with a public method called "a()", there's no problem.

thanks I have been testing I can't get to work what I have created a little more complicated  but if the struck is right I have go back to testing thanks for your help.

What do you mean it doesn't work? It works in your example when you add $this to the geta() call..?

[purencool]

yes the example works but I must have another issue driving the error. I was just confirming  that  the theory was right thanks again
