optional arguments
Quite a lot of programming languages have optional arguments in functions. In some, you simply put myvar = 'default' in the argument list, and myvar will equal default if not defined. In other languages you redefine the function, one with and one without the optional argument. Does PHP have something like this?

Re: optional arguments
You had it right on in your question:
function something($required, $optional='default', $optional2=NULL) { // DO SOMETHING }
