PHP Functions and Variable Scope in PHP

This is a little tutorial on functions and variable scope, hope you enjoy.
In php as you write your code it is very likely that you will find yourself doing one action over and over possibly one that is very lengthy and when it's lengthy it's not always fun to make the code each time, this is the very reason functions were designed.

A function is a declared piece of code that has code as members of it. All the things you use when you are coding are functions like print(), echo() and exit(). You can create your own functions in PHP to do similar things as these.
