PHP Introduction

PHP scripts are generally saved with the file extension .php.

Usually one line of code contains just one statement, but we can have as many statements on one line as you want.

PHP Opening and Closing Code is <?php and ?>

Hello World! Example:

<?php

echo "Hello World<br><h1>Hello From MaHi</h1>";

?>

The code above generates the following result.

Hello World
Hello From MaHi
