1.思路:用户查看物品id的时候,记录查看物品id,以及物品的其他信息,[以ID-物品信息,ID-物品信息]格式存入cookie
数据库Helper:mysqlHelper.class.php
<?php /* @author:luowen @time:2013-12-17 @desc:mysql helper */ class MysqlHelper{ private static $instance = null; private $host = null; private $username = null; private $password = null; private $database = null; private $conn = null; final private function __construct($conf){ $this -> host = $conf['host']; $this -> username = $conf['username']; $this -> password = $conf['password']; $this -> database = $conf['database']; $this -> conn(); $this -> query("use " . $this -> database); } private function __clone(){} private function conn(){ $this -> conn = mysql_connect($this -> host,$this -> username, $this -> password); if(!$this -> conn){ die(mysql_error()); } } public static function getInstance($conf){ if(!(self::$instance instanceof self)) MysqlHelper::$instance = new self($conf); return MysqlHelper::$instance; } public function getOne($sql){ $source = $this -> query($sql); $resSource = null; if($row = mysql_fetch_assoc($source)){ $resSource = $row; } $this -> freeSource($source); return $resSource; } public function getAll($sql){ $source = $this -> query($sql); $resSource = array(); while($row = mysql_fetch_assoc($source)) { $resSource[] = $row; } $this -> freeSource($source); return $resSource; } public function query($sql){ return mysql_query($sql,$this -> conn); } public function close(){ mysql_close($this -> conn); } private function freeSource($resource){ mysql_free_result($resource); } }
2,数据库配置文件db.inc.php
<?php /* db configure file */ $conf = array( "host" => "localhost", "username" => "root", "password" => "luowen", "database" => "test" );
3,数据表模型luowenModel.class.php
<?php /* luowen表模型 */ class LuowenModel{ private $tableName = "luowen"; private $dbInstance = null; public function __construct($db){ $this -> dbInstance = $db; } public function getOne($id){ $sql = "select * from " . $this -> tableName . " where id = " . $id; $res = $this -> dbInstance -> getOne($sql); return $res; } public function getAll(){ $sql = "select * from " . $this -> tableName; return $this -> dbInstance -> getAll($sql); } }
