The first thing you will want to do is download the FPDF class files from http://www.fpdf.org/ – this site is also an excellent resource for the FPDF class, if you get stuck then a look through the manual or frequently asked questions will help out no end.
When writing a PHP based site – developers often also have to integrate with a database (otherwise the site tends not to be very exciting!) and a popular technology for this is a flavour of SQL. Rather than go through the basics of database queries using SQL (which if enough people ask me for – I certainly will do in the future) I have decided to write specifically about the mechanics of the JOIN command. The SQL Join command allows us to pull and combine data from two or more tables, where the result can be modified by specifying different data relationships between the tables.
