   // Adding comment meta data
   $comment_id = 123;
   $meta_quey = ‘user_rating’;
   $meta_value = 5;
   
   

   add_comment_meta( $comment_id, $meta_quey, $meta_value );

   $comment_id: The ID of the comment you want to attach the metadata to.
   $meta_quey: A unique key that identifies the type of metadata you are storing.
   $meta_value: The value associated with the metadata. In this case, a numeric rating of 5.

   This will add a custom field named user_rating with the value 5 to the comment with ID 123.
