Re: form validataion?

The whole set of is_* functions are useful, like is_numeric() and is_string() and such. Regular expressions are also mega-useful if you want data to be in a very specific format, like email addresses and such. isset() is also a good function to call at the beginning of your validation function or script just to make sure that if a variable is needed on a page, it's been set properly on the form.
