What are the best practices for ensuring that PHP modules are properly integrated with Apache for smooth functionality?

To ensure that PHP modules are properly integrated with Apache for smooth functionality, it is important to make sure that the necessary PHP module is installed and enabled in Apache configuration files. This can be done by loading the PHP module using the LoadModule directive in the Apache configuration file (httpd.conf) and adding the appropriate handlers for PHP files. Additionally, it is important to restart the Apache server after making any changes to the configuration files to ensure that the changes take effect. ```apache LoadModule php7_module /path/to/php_module.so AddHandler php7-script .php AddType text/html .php ```
