No, that's showing how is_dir works, not necessarily "live code".

And you won't find examples for everything you want to do. There are
too many possibilities. You need to get familiar with the language and
function calls so you can look up what you need. I find having a local
copy of the PHP doc (as a windows help file) is quite useful.
To get a file extension, check out
http://us2.php.net/manual/en/function.pathinfo.php
Then you can compare on the extension. Just a warning - if the files
are uploaded by users, don't depend on the extension being correct.
