Functions in PHP: Part II

This lesson introduces the fundamentals of creating user-defined functions. These functions help you avoid repeating yourself when coding by allowing you to call the same block of code multiple times without having to rewrite if for eawch time it is called. These user-defined functions can take arguments to them to perform different operations. In the example below, the function aboutMe takes the arguments $name and $age, and echoes a line using those two parameters. When this function is called, it will output "Hello! My name is Elise, and I am 29 years old."
