EXPLANATION
Its very easy to create your own PHP function. Suppose you want
to create a PHP function which will simply write a simple message on
your browser when you will call it. Following example creates a function
called writeMessage() and then calls it just after creating it.
Note
that while creating a function its name should start with keyword
function and all the PHP code should be put inside { and } braces as
shown in the following example below −
<?php
/* Defining a PHP Function */
function writeMessage() {
echo "You are really a nice person, Have a nice time!";
}
/* Calling a PHP Function */
writeMessage();
?>
