Running MySQL from .php files [resolved]

[Acidic]

I'm very new to PHP, I've read tutorials, been introduced to Mr. MySQL and tickered. I have been wondering, how to do you run MySQL code from a php file?

All the tutorials I've read talk about using MS-DOS prompt to create the database. Well that is all fine and dandy, until I need a visitor to be able to add to my DB.

Let's say I wanted to add a new record in a table called "mydb", where all the data is taken from textfields in the HTML. How would I do this?
