How to add a PHP code in a HTML file?

A PHP script can be placed anywhere in the document and starts with as follow:

<?php and ends with ?>


The default file extension for PHP files is “.php”.

A PHP file normally contains HTML tags, and some PHP scripting code.

Below, we have an example of a simple PHP file, with a PHP script that uses a built-in PHP

function “echo” to output the text “Hello World!” on a web page:


<!DOCTYPE html>



<h1>My first PHP page</h1>


echo "Hello World!"






My first PHP page

Hello World!
