Chapter 1
Examining the Pieces of Web Programming

IN THIS CHAPTER

Understanding how simple web pages work

Incorporating programming into your web page

Storing content in a database

At first, diving into web programming can be somewhat overwhelming. You need to know all kinds of things in order to build a web application that not only looks enticing but also works correctly. The trick to learning web programming is to pull the individual pieces apart and tackle them one at a time.

This chapter gets you started on your web design journey by examining the different pieces involved in creating a simple web page. Then it kicks things up a notch and walks you through dynamic web pages. And finally, the chapter ends by explaining how to store your content for use on the web.
Creating a Simple Web Page

Before you can run a marathon, you need to learn how to walk. Likewise, before you can create a fancy website, you need to know the basics of how web pages work.

Nowadays, sharing documents on the Internet is easy, but it wasn't always that way. Back in the early days of the Internet, documents were often created using proprietary word-processing packages and had to be downloaded using the cumbersome File Transfer Protocol (FTP). To retrieve a document, you had to know exactly what server contained the document, you had to know where it was stored on the server, and you had to be able to log into the server. After all that, you still needed to have the correct word-processing software on your computer to view the document. As you can imagine, it wasn't long before a new way of sharing content was required.

To get to where we are today, several different technologies had to be developed:

A method for linking related documents together
A way for the document reader to display formatted text the same way in any type of device
An Internet standard allowing clients to easily retrieve documents from any server
A standard method of styling and positioning content in documents
This section describes the technology that made viewing documents on the Internet work the way it does today.
Kicking things off with the World Wide Web

In 1989, Tim Berners-Lee developed a method of interconnecting documents to make sharing research information on the Internet easier. His creation, the World Wide Web, defined a method for linking documents together in a web structure, so that a researcher could follow the path between related documents, no matter where they were located in the world. Clicking text in one document took you to another document automatically, without your having to manually find and download the related document.

The method Berners-Lee developed for linking documents is called hypertext. Hypertext embeds links that are hidden from view in the document, and directs the software being used to view the document (known as the web browser ) to retrieve the referenced document. With hypertext, you just click the link, and the software (the web browser) does all the work of finding and retrieving the related document for you.

Because the document-viewing software does all the hard work, a new type of software had to be developed that was more than just a document viewer. That's where web browsers came into existence. Web browsers display a document on a computer screen and respond to the reader clicking hypertext links to retrieve other specified documents.

To implement hypertext in documents, Berners-Lee had to utilize a text-based document-formatting system. Fortunately for him, a lot of work had already been done on that.
Making sense of markup languages

Markup languages were developed to replace proprietary word-processing packages with a standard way of formatting docum
