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.

Language constructs that act like functions look very much like built-in functions in the way they are used. If you want to print a string, you can choose to use echo, which is a language construct; or print, which is also a language construct. There are small differences between echo and print, and echo is the most commonly used. When comparing the two, echo doesn't have a return value and has the option of multiple parameters, whereas print returns a value that can be used in an expression and allows only one parameter. echo is the most flexible of the two and is a tiny bit faster. Language constructs can be used with or without parentheses. In contrast, callables are always used with parentheses:

// echo is a language construct
echo 'hello world'; // echo...
