wp_xmlrpc_server_class WordPress Filter Hook

The wp_xmlrpc_server_class hook allows a user to change the class used for the XML-RPC server. By default, the WordPress XML-RPC server uses the wp_xmlrpc_server class, but this hook can be used to change it to a different class. This can be useful if you need to extend the default XML-RPC server functionality or if you want to use a different XML-RPC server implementation.
