Zendframe Implement a voting module

Analysis: Get the User IP, determine whether the IP is disabled, and then determine if there is no vote today to make the corresponding operation ...   The main steps are as follows:   Configure Application.ini to allow items to connect to a specified database   [MySQL] Db.adapter = Pdo_mysql Db.params.host = localhost Db.params.username = root Db.params.password = db.params.dbname=votedb & nbsp Initialize the database adapter   <?php  //to do a parent class that is specifically for other controllers to inherit  class Basecontroller extends zend_controller_action{  Public Function init () { //initialization database adapter   $url = constant ("Application_path"). Directory_separator. ' Configs '. Directory_separator. ' Application.ini ';   $dbconfig = new Zend_config_ini ($url, "MySQL");   $DB = zend_db::factory ($dbconfig->db);   Zend_db_table::setdefaultadapter ($DB);  } &nbsp  //CREATE TABLE Model   <?php//This must inherit zend_db_table, otherwise it is not a table model  class Item extends zend_db_table{ Bsp Protected $_name = ' item '; &NBSP}//Voting controller   <?php require_once ' basecontroller.php '; Require_once Application_path.
