How can one ensure that PHP pages are displayed correctly, instead of showing only the source code?

To ensure that PHP pages are displayed correctly instead of showing only the source code, you need to make sure that your web server is configured to properly handle PHP files. This typically involves installing PHP on your server and setting up the appropriate file extensions to be processed by the PHP interpreter. Additionally, ensure that your PHP files have the correct file extension (e.g., .php) and that your code is enclosed within <?php ?> tags.

<?php
// Your PHP code here
?>
