Functions are basic blocks of code that work together. Functions can be used from the core PHP or can be created by users.

To create a function, use the following syntax: function function_name(arg1, arg2, ... argX)

{

//Any valid php code here

}

To use a function, use the following syntax:

function_name(arg1, arg2, ... argX);

A PHP function is a block of reusable code that performs a specific task. Functions can accept input parameters and return a value, making them useful for organizing and simplifying code. They allow you to encapsulate logic and execute it whenever needed within a PHP program.
