Woocommerce, If Purchase more then 9, change Role!


I got this code and its working great.

    add_action( 'woocommerce_order_status_processing','change_role_on_purchase' );     function change_role_on_purchase( $  order_id ) {       $  order = wc_get_order( $  order_id );       $  items = $  order->get_items();       $  products_to_check = array( '2205','2207','2209','2211','2213','2226','2227','2230','2450','2444','2235','2237','2238','2239','2240'  );       foreach ( $  items as $  item ) {         if ( $  order->user_id > 0 && in_array( $  item['product_id'], $  products_to_check ) ) {             $  user = new WP_User( $  order->user_id );             // Change role             $  user->remove_role( 'Customer' );             $  user->add_role( 'Distributor' );             // Exit the loop             break;         }     } } 

But, I want to add:- If user purchase more than 9, change role to Distributor.
