How to create a function in PHP

Definition: PHP has many functions predefined, but often you will be using functions that you create yourself. Creating a function is very easy, here is how:

function FunctionName()
{
code to execute;
}

First you define the function name, and then what the function will do. Here is an example:

function examplefunction () 	
{ 	
print "Hi, I'm a Function 
"; 
}
