Learn the fundamentals of PHP from structural programming to object-oriented techniques.

Web Development with PHP

This highly interactive module introduces us to fundamental programming concepts in PHP—one of the most popular languages in the world. It begins with a simple “Hello, World!” program and proceeds to cover common concepts such as conditional statements, loop statements, and logic in PHP. It then reflects upon the idea of functions and arrays, as well as the power they give to the programmer to write better code.

Finally, it dives deeper into advanced concepts such as classes, inheritance, and exception handling in PHP. By the time we're done, we’ll have a good grip on the basics of PHP and will be ready to study advanced concepts.

## What are Variable Variables?
Using PHP, we can access data through dynamic variable names. The name of a variable can be stored in another variable, allowing it to be accessed dynamically. Such variables are known as *variable variables*.

To turn a variable into a *variable* variable, you put an extra `$` sign in front of your variable. This method is illustrated in the following figure:
