OO : Accessing foreign methods

[Anon]

Hi, my question is the following :

How can you access a method of an object
from an another object?

For example if I have 2 classes:

class class1
{
function method1 ()
{
..
}
}

class class2
{
function method2 ()
{
..
}
}

and 2 objects :

$object1 = new class1;
$object2 = new class2;

How can I access the method1 from the
object2?

I know it's possible to do the following in
class2 :

global $object1;

$object1->method1();

but I don't think it's a good oo practice 🙂

Thanks for your answers.

A few possibilities which may or may not be appropriate for your situation:

1. Pass object1 as a parameter, e.g.
   function method2(&$object)
   {
   $object->method1();
   }

2. Make object1 a member of class2, e.g.
   class class2
   {
   var $object;
   function class2()
   {
   $object= new class1();
   }
   }

3. Have class2 inhert class1. In this case you have only one object, e.g.

class class2 extends class1
{
function method2()
{
$this->method1();
}
}

Which method you choose depends on the relationship between the two classes.
