So I'm managing two class/objects... one for the main site and one for mobile but to reduce redundancy I didn't duplicated general functions... how do I reference the function in another class..

eg:

PHP Code:


$object_one = new object_one;
$object_two = new object_two; 


in object two I want to do this

PHP Code:


class object_two {
function() {
$object_one->function_one();
}
} 


Assuming the class name is object_one you can call it by object_one::function_one()

I've actually tried that and it didn't work

i actually figured it out over time and hopefully this could help others

PHP Code:


$object_one = new object_one;
$object_two = new object_two($object_two); 


PHP Code:

//Object Two

class object_two {
var object_one;

function object_two(object_one) {
$this->object_one = $object_one;
}

//Calling Functions
function something_cool() {
//Call
$this->object_one->another_function();
}
} 


Assuming the class name is object_one you can call it by object_one::function_one()

But only if the method is declared as static (I believe).
A static method being a method that is shared by every instance of a given class.

The second way is "proper" in my opinion, at one exception.
Be aware that PHP does a copy of $object_one when you pass it as a parameter to $object_two.
This means, that if you change somethinf from the inside of $object_two to the $object_one object that is encapsulated in it, it will not reflect on the real $object_one!

To avoid this, you have to use what is called a "passage by reference" of the object $object_one:

PHP Code:

//Object Two

class object_two {
  var object_one;

  function object_two(object_one) {
    $this->object_one = $object_one;
  }

  //Calling Functions
  function something_cool() {
    //Call
    $this->object_one->another_function();
  }
}  

$object_one = new object_one;
$object_two = new object_two(&$object_one); 


Notice the "&" before $object_one, this is what tells the PHP engine not to copy the object, but to share the same reference to the place where the object is stored in memory.Here is the PHP.net doc page relative to this:
