it's also called auto-completion...start typing a variable name in and you
have to option completing it by selecting from a list...or, you can see the
next param that's supposed to be entered if typing a function - complete
with the param data type. that was one kind of 'hinting' i was guessing at.
just wasn't sure that was what you meant. i know it wasn't now.

yes, that's what i meant. as it is though, i haven't really had a need to
implement an interator on a custom class in php. arrays work fine for just
about everything in php. i did, however, enjoy reading the article you
referenced about doing just that - custom classes implementing iterators.
