Hi
I've been coding with PHP for quite some time now, but still I have never had to use keys in my databases, so I've never learned how too.. Now I realize that it is more efficient to call users in a db with a 'uid' field instead of their user name.
-How do I go about setting this up?
-How do I enter a new row into my db - do I need to set a value for the 'uid' field or will it increment itself? (that seems to be the point anyways)?
-Any helpful articles / posts you can point me to regarding this?
Thanks, Geoffroy.
