This highly interactive course introduces you 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 on 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 in order to teach about advanced concepts such as Classes, Inheritance and Exception Handling in PHP. By the time you're done, you'll have a good grip on the basics of PHP, and will be ready to study advanced concepts.

## Introduction
The scope of a variable refers to the variable's visibility, i.e., which part of the program can access that variable.

## Types of Variables
There are two types of variables depending on the scope (or visibility):
- local variables
- global variables
### Local Variables
Variables that are defined within a function are inside a local scope hence are called **local variables**. These variables cannot be accessed outside of the function they are declared in.
