Valid class

Question: Is you define an associative array that is empty and you initialize all of the elements of the array, would this be a good item to make into a class that can be called from anywhere?? I have a large number of attributes for a project and want to pass a single parameter (the associative array/class) to and fro without having a large number of parameters for each function. I would rather have the function extract what it need from the class/array. Robin Kopetzky
