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.

A dog can be described by using certain states, such as color, breed, age, and so on, and performs certain actions, such as barking, running, wagging its tail, and so on. A table fan can be described by color, speed, direction, and so on, and perform actions such as changing speed, changing direction, rotating, and so on.

In OOP, data and code are bundled together into an entity, which is known as an object. Objects interact with each other. Consider a teacher object and a student object. The teacher might have certain subjects to offer and the student might enroll in these subjects. Hence, if we consider enrolling as an action of the student, then the student object might need to interact with the teacher object regarding the available subjects and register...
