When the result is successful ~ ~ when multiple tables and multiple fields are successful, the information must be modified in the way associated with the table: the copy code is as follows: UPDATE `user`join `binding`on `user`.`uid` SET `user`.`ren` = "", `binding`.`renren _ token` = "", `binding`.`rt _ time` = "" WHERE `user`.`uid` ='. $in ['uid']
