What steps should be taken to ensure that a web server supports PHP and is properly configured to interpret PHP files?

To ensure that a web server supports PHP and is properly configured to interpret PHP files, you need to make sure that PHP is installed on the server and that the web server is configured to recognize and process PHP files. This typically involves configuring the web server to use the PHP module or FastCGI, setting up the appropriate MIME types, and ensuring that PHP files have the correct file extension (e.g., .php).

<?php
// This is a PHP code snippet to check if PHP is properly configured on the server
phpinfo();
?>
