How two functions in the same class communicate with each other.

A function in a class can call another function in the same class by 
using the class function call ->.  Calling to itself use this-> as 
shown in the eg below.

Alternatively a class variable (variable scoping would be nice) can be 
set up or variables can be passed by reference from one function to 
another, again using this->someFunction(aParameter)

class Sample
{
    function fOne()
    {
        $aVariable = $this->fTwo();
        //$aVariable is set to the retuen value of fTwo and can then be 
used for whatever.
    }

    function fTwo()
    {
        //do something
        return someValue;
    }
}
