Building Dynamic Sites using PHP

First I'm a network administrator and php developer. Not a writer.

Now, Here is the tech...

First Let talk a little about PHP

What is PHP? ..
Taken from http://php.net/manual/preface.php

"PHP, which stands for "PHP: Hypertext Preprocessor", is an
HTML-embedded scripting language. Much of its syntax is borrowed from C,
Java and Perl with a couple of unique PHP-specific features thrown in.
The goal of the language is to allow web developers to write
dynamically generated pages quickly"

What is MySQL?
Taken from
http://www.mysql.com/documentation/mysql/commented/manual.php?section=Introduction

MySQL is a very fast, multi-threaded, multi-user, and robust SQL
(Structured Query Language) database server. 

MySQL is free software. It is licensed with the GNU GENERAL PUBLIC LICENSE 

Now lets start coding a little ...
