Two very usefull functions to have around.

(note: dollarfy requires commify to work)

A database API written in Perl for a MySQL.

You will need to edit the settings for your server.

Enojy

A little function that returns a greeting based on the local time.

Simple function to check for a valid email address. Makes sure the @ and a . are in the right place. There is most likely a perl package on CPAN that would be more extensive, but this happens to work for my uses.

Just a simple check to make sure that a person's email address matches their domain.

For example .. in a form you have 2 textboxs .. 1 for their website url, the other for their email address. This checks to see if the domains for the email address and the website url match.
