Well, I ran the edited code in my previous reply and it worked just fine, and there is nothing wrong with the concept as you presented in your original post (other than those syntax errors). If the "real" code is not working, then perhaps we need to see the real code to find out where the real problem is.
The only thing I can think of without seeing the code (other than other syntax errors) is if you are declaring any of those functions as private, since private class attributes are not inherited. If that is the case, you need to define them as "protected" instead if you want them to be inherited but not public.
Extending mult level classes
I am not being able to do this… is there any way ?
[code=php]
<?php
class one{
function one_(){
return “this is one”;
}
}
class two extends one{
function two_(){
return $this->one_();
}
class three extends two{
function three_(){
return $this_>two_();
}
}
// assume there’s class four which extends class three n like wise
$objThree = new three;
// here’s my problem
// error : Call to undefined method three::two_()
echo $objThree->three_();
}
?>

@NogDogJul 31.2008 — #Thankx for the correction NogDog ! Bt do u really think I have that simple class structure in my real app n copied n pasted in here ? There r hundreds of lines of code mate ! several functions in every classes. Fixing the braces n _> to -> isn't my problem to be solved.
N [B]ss1289 [/B]! i can't call into constructor like u suggest... coz i won't know how many functions gonna be added later... if i follow u i will have to call all everytime. And also i guess it's resource much consuming coz i will have to call them even if i don't have to use it. N i don't have to use all functions everywhere.
I just wanna know why i simply can't call a grand father class's method into grand child object simply. Why a grand child class method forgets his grand parent methods ?[/QUOTE]
