4. PHP Functions
• PHP functions are similar to other
programming languages. A function is a
piece of code which takes one more input
in the form of parameter and does some
processing and returns a value.
• You already have seen many functions
like fopen() and fread() etc. They are
built-in functions but PHP gives you option
to create your own functions as well.

5. PHP Functions
• There are two parts which should be
clear to you:
Creating a PHP Function
Calling a PHP Function

6. Creating PHP Function
• Note that while creating a function its
name should start with
keyword function and all the PHP code
should be put inside { and } braces.

parameters inside a function. You can
pass as many as parameters your like.
These parameters work like variables
inside your function.

10. PHP Functions returning value
• A function can return a value using
the return statement in conjunction
with a value or object. return stops the
execution of the function and sends the
value back to the calling code.
