[OO] Classes within a Class

[Hotkey]

Hi there !

Im just trying to use a class within a class like the following :

include ("NewClass.inc");

class FirstClass {
  var $newClass = new NewClass();
  //[...]

  function NewClass {
  $this->newClass->someFunnyNewClassFunction();
  }
}

with this i get the error :
parse error, unexpected T_NEW at [...]
i also tried

$newClass = new NewClass(); //so without the 'var'

with this i get the following :
PHP Parse error: parse error, unexpected T_VARIABLE, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or '}' in [...]

what am i doing wrong ?

I can declare the new Class from within a function, but thats not what i want to do - i want to keep it global, so that i can use this objekt in every function in "FirstClass"

What you want todo (I think) is extend the NewClass class, this way you can use all functionality inside NewClass and create new functionality in your FirstClass class.

class FirstClass extends NewClass {

...code...

}

Hope this helps...

no, that is not what i intended to do.
I just want to create an Objekt of NewClass in my FirstClass -
so i could use it in my FirstClass functions.
Extend it would work too, but what if need 2 or more Classes
implemented in FirstClass.

Within my FirstClass functions it's possible to create a new Object of NewClass, but then i have to create one new Objekt of it in every Function - and thats not the way OO is meant for :-)

So in short words :
I need to create a global accessible Objekt (accessible in FirstClass) of NewClass in FirstClass ...

anyway thanks 4 your answer !

Heh, sorry, but its "Object".

In Germany it's written "Objekt"

You can't initialize a variable where you declare it in a class. You will have to create an object constructor which initializes the variable upon creation. Try this:

include ("NewClass.inc");

class FirstClass
{
  var $newClass;
  //[...]

  function FirstClass()
  {
    $this->newClass=new NewClass();
  }
}

Hope that helps...
