In this article, I will explain how the simple function can be used in PHP.

Simple Function in PHP

A function declaration starts with the special word 'function'.
A function name starts with a letter or underscore, followed by any number of letters, numbers, or underscores.
A function names are case-insensitive.
A function is block of code that can be executed whenever we need it.

function functionname()
{
code to be executed;
}

The following example show the simple function that writes any name when it is called:

<html>

<body>

<h2 style="color: steelblue;">Simple Function Loop example</h2>

<?php

function writeName()

{

echo "C-Sharpcorner";

}

echo "Welcome To...";

writeName();
