I need class of an object or better design

function to return class of $this

[shumboom]

I have searched all over for this simple question but cannot find the answer. Also I am not sure if I am doing the right thing and maybe I should change my design. I have a function which needs to do something slightly different depending on its class

Class A{
function develop(){
...
if (class of $this=='B') { ...};
...
}

Class B extends Class A{

}

$obj=new B;
$obj->develop();

I think I have 3 choices here

1. Have two functions in each class with a slightly different code.
2. Get the parent of the class (as above) and code accordingly
3. Split the function into two. Retain develop in Class A, and it calls a function SpecialLine which is in both classes.(not sure how to ensure the right function is called)

Which is the best option and its solution and is there anoter way?
thanks,Shumit

I believe this should answer your question: [us.php.net...]

See Example 3, in particular, for being able to both use, and modify, a parent class's function.
