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.

  3. Create a PHP file called Student.php inside the Student directory.
  4. Declare a Student class where the Student class has been namespaced as Student and has two member attributes, $name and $title, which are student by default. The constructor method accepts the student's name as an argument. The argument is hinted with its desired type as string (anything other than string will produce an error) and assigns it to the $name property using $this->name. So, whenever we instantiate the Student class, we should call the class by its namespace, such as the...
