This is pretty much a basic “How to” for making a very basic guestbook that uses a database instead of text. I go over everything from making the database to the table, the html form and actual posting. If you watch this video you will pretty much see the basic idea of what a guestbook is, how they work, and how to make a basic one yourself.
This video has two parts, so to understand fully, please watch both.
I’ve decided to record how to make complete solutions for a certain problem from a High School programming competition, and the solution for it.
The problem: You are to write a program which will input a positive integer n and output the number of
divisors of n and the sum of those divisors. (Note: by divisor we mean a positive integer

Developers often use the handy features included with databases to create solutions in PHP for what ever needs to be satisfied.

I also marginally go over importing and how to import.
