[PHP] PHP 5.0 and mysql

This is going to a very naive question, but how do I make mysql work with PHP 5? I run PHP on IIS on Windows 2000. Help!

[PHP] PHP mail

I am relatively new to PHP and could use some help. I have a form, which is basically in an email format, from, subject, and message. How do I then send this to an email? I know a bit about the mail function, somebody show me the ropes please! Eustace
