What steps should be taken to configure a web server for PHP usage?

To configure a web server for PHP usage, you need to install PHP on the server and configure the web server to recognize and process PHP files. This typically involves installing a PHP module for your web server (such as mod_php for Apache) and updating the server configuration to handle PHP files. ```apache # For Apache web server LoadModule php_module modules/libphp.so AddHandler php-script .php Include conf/extra/php.conf ```
