Data Validation

[corliss at alaskapm.org]

Greetings:

I was recently talking to some people off list about using regexes for data
validation.  I thought this was a good topic for the list, too, though, so I'm
asking for your thoughts:  what are your favourite regexes to use for common
data types?

Here's a few that I use often:

	e-mail:  /^[\w\.]+\@[\w\.-]+\.\w{2,3}$/
	telephone:  /^(\(?\d{3}\)?[\s-]?)?\d{3}[-\s]?\d{4}$/
	zip code:  /^\d{5}(-\d{4})?/

Anyone have any other nifty ones to share?
