Newbie question about Classes

Hi, I have now been 3-4 months writing PHP-codes and read the PHP manual throughout. But there is one thing I can't figure out properly (I think it's not covered enough in the manual): Classes! When and why would I use it? Is it only to group certain functions or does it have a special function? Thanks!
