Creating a Function

Creating your own function is easy; just start with the keyword function followed by the function name and parenthesis. After that place your code between two curly braces { and } called the opening and closing braces, respectively. Now you can use the function as many times as you need it. This saves you the trouble of having to re-type the code every time.

The code below demonstrates a function that outputs a message to the screen

<?php

              functionechoMessage() {

                            echo “Hello, I am a PHP function!”;

              }

              echoMessage();

?>

Output:

              Hello, I am a PHP function!
