Interacting with Web Forms

HTML forms are one of the key ingredients of any dynamic website because they can enable the users of a site to interact with it. Therefore, using data from forms from within PHP is very important.

Remembering Users

HTTP is a stateless protocol, a web browser connects to a web server, sends a request, and gets a response. Then, the connection is closed. The consequence is the next time the same client sends a request to the same web server, it is a new request, so the web server cannot identify the caller. This is, of course, a problem for applications in which state must be maintained, for instance e-commerce applications with a shopping-cart functionality.

Using Files on the Server File System

Although databases are very common, using the file system to store data can be a real alternative. Often, it is easier to implement that way. Sometimes, it is faster, and much more importantly, all hosting providers have file access enabled, whereas database support might only be available at extra cost.

Making Data Dynamic

This tutorial tackles quite a number of databases and shows the basic operations with them: connecting, sending SQL statements, and evaluating the return values. No matter what your database-driven web application must do, it always has to do these steps.
