What are some potential reasons for PHP scripts displaying as plain text instead of executing on a local server setup?

The issue of PHP scripts displaying as plain text instead of executing on a local server setup could be due to the server not recognizing PHP files as executable scripts. This can be resolved by ensuring that the server has PHP installed and configured properly. Additionally, the server's configuration files may need to be updated to include directives to handle PHP files.

<?php
// Ensure that PHP scripts are recognized and executed by the server
// For Apache server, add the following lines to the .htaccess file:
// AddType application/x-httpd-php .php
// AddHandler application/x-httpd-php .php
