Welcome, reader, to the world of PHP. You're about to learn to use the most powerful web development language that can be found, and, what's more, you will do so with the minimum of fuss. I myself started programming in PHP back in 1997 when Perl was at its apogee, and after only two weeks, I had converted most if not all of my Perl scripts into PHP. The reasons I were drawn so strongly towards PHP are many, but mainly it was ease of use - even after having used Perl for so long. Through this book, I hope for you to be able to switch to PHP in the same kind of time frame, if not less. Back when I made the switch, I was not lucky enough to have a book like this to learn from.

A fundamental characteristic of the Web is the stateless interaction between browsers and web servers. As discussed in Chapter 1, HTTP is a stateless protocol. Each HTTP request a browser sends to a web server is independent of any other request. The stateless nature of HTTP allows users to browse the Web by following hypertext links and visiting pages in any order. HTTP also allows applications to distribute or even replicate content across multiple servers to balance the load generated by a high number of requests. These features are possible because of the stateless nature of HTTP. This stateless nature suits applications that allow users to browse or search collections of documents. However, applications that require complex user interaction can't be implemented as a series of unrelated, stateless web pages.
