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.

Looping

A loop is a block of statements written once but executed several times. The code within a loop or the body of a loop is executed a finite number of times, determined by whether certain conditions are met or they may be infinite!

In this chapter, we will be discussing for, foreach, while, and do…while loops with their structures and examples.

Bounded Loops versus Unbounded Loops

A bounded loop has a loop iteration limit and hence executes till that boundary is met. To restrict it to that finite number of iterations, the number of iterations is easily visible in the loop condition or in loop statements and the language constructs assure that it won't loop beyond that.

Again, an unbounded loop iterates until a certain condition is met and the condition can be controlled from inside the loop. Bounded loops are also called count-controlled loops as you can control the iteration count with the help of language constructs; similarly, unbounded loops are condition...
