PHP Global Variables

[jaimitoc30]

Hi, I have a little problem.  I have a variables that is used inside a functions class.  It is an internal variable for the function.  I need to know how to access the value of that variable from my main problem, the function is already returning another value, so I need a way to read that value that is inside that function which is inside a class.  I would appreciate any assistance.
