What I want to know is if the variable assignment is unknown, as in a user form. Would I then just initialize the variables to 0 ?

// I assign null to the variable if I'm not sure what type it's going to have. $var = null;
// 0 and FALSE are also ok choices, I try to use them for integers or booleans
// If you're talking about I think you're talking about (register_globals) then // isset() won't suffice because the $_POST and $_GET indices get registered as // global variables automatically.
