How can troubleshooting steps be taken to resolve issues where PHP files are not being parsed and instead trigger a download dialog in Apache?

To resolve the issue where PHP files are not being parsed and instead trigger a download dialog in Apache, you can check if the PHP module is enabled in your Apache configuration file. You should also ensure that the file extension for PHP files is set to ".php". Additionally, make sure that the PHP handler is correctly configured in your Apache configuration. ```apache <IfModule mod_php7.c> AddType application/x-httpd-php .php AddType application/x-httpd-php-source .phps </IfModule> ```
