Hi,
Perhaps I have become thick with the years, but I can't imagine why a
function should be required to modify several different global
variables.
If you don't want to enter into all the details and subtleties of OOP,
fine. But using and object to pack all the data required by a given
process, and pass it to any function that might need it is even easier
than having to remember the names of every global variable involved in
a complex procedure.
I am completely new to PHP, but it is universal programming common
sense, like using structs in C, or Records in Pascal.
