2. A PHP script starts with <?php and ends with ?> .
3. To see the result of php code in browser, you need to save the file consists of php code as ".php" extension. eg. [Demo.php]
4. PHP statements end with a semicolon (;).
Demo.php
<?php
// write the PHP code goes here
?>

<html>
<body>
<h1>Welcome to first PHP page</h1>
<?php
