Overview of this book

Do you want to build your own websites, but have never really been confident enough to turn your ideas into real projects? If your web development skills are a bit rusty, or if you've simply never programmed before, The PHP Workshop will show you how to build dynamic websites using PHP with the help of engaging examples and challenging activities. This PHP tutorial starts with an introduction to PHP, getting you set up with a productive development environment. You will write, execute, and troubleshoot your first PHP script using a built-in templating engine and server. Next, you'll learn about variables and data types, and see how conditions and loops help control the flow of a PHP program. Progressing through the chapters, you'll use HTTP methods to turn your PHP scripts into web apps, persist data by connecting to an external database, handle application errors, and improve functionality by using third-party packages. By the end of this Workshop, you'll be well-versed in web application development, and have the knowledge and skills to creatively tackle your own ambitious projects with PHP.

In fact, it's also used in the communication between machines; for example, for fetching data from a database, which involves the application system on one side and the database system on the other side. In this case, the application is the client for the database system.

HTTP is the most commonly used protocol for web applications and, since it could take up a whole book itself, we'll cover only the most important part here, explaining how it works.

Each web application takes a request and prepares a response for it. Usually, the Request-Response cycle for a web application looks similar to this:

  1. The client makes a request; for example, GET...
