What steps are involved in adding a module to Apache for PHP functionality?

To add PHP functionality to Apache, you need to enable the PHP module in the Apache configuration file. This involves loading the module and configuring it to handle PHP files. Once the module is enabled, Apache will be able to process PHP scripts and serve dynamic content. ```apache # Load PHP module LoadModule php_module modules/libphp.so # Configure PHP to handle .php files AddHandler php-script .php ```
