Hi..

I have seen these symbol in the use of the class...

when we want to refer to the member (data member, member function) of some class than we use

objectname -> class member

So it is a kind of pointer which tell to look for the class member for the given object of that class..

See classes in PHP manual for more reference..

have a nice day

Finally i can help some one:

Class sql
private $db;

 etc
 etc

Then you can call the field $db from somewhere else in your application with:

this->db

I suck at OOP, so if you want an in depth explanation you got a lot of reading to do.
