[SOLVED] functions

I'm not really that new to PHP.. but I've never really used functions. I started looking at functions and I see two different things. Firstly I see a function being called as $variable = function(); but I've also seen $variable -> function(), or something similar. Is there a difference, or am I just confusing things?

The $variable->function() is used because $variable is an object (OOP Object Oriented Programming). So it is a function/method inside of that class.

 

The first is normal function usage set $variable to the return of function(); Where as the $variable->function(); is making a call to that function.

 

Hope that clears it up for you.
