What steps can be taken to troubleshoot and resolve the issue of PHP files not parsing on the server?

If PHP files are not parsing on the server, it may be due to the PHP module not being enabled or configured correctly. To resolve this issue, ensure that the PHP module is installed and enabled on the server, and that the file extensions are set to be processed by PHP. ```apache # Ensure PHP module is enabled LoadModule php_module modules/libphp.so # Set PHP file extensions to be processed by PHP AddType application/x-httpd-php .php ```
