CI cookie 存放数组

 1 #ci  cookie  由于不能存放数组，所有必须序列化之后在存入数组中

 3         #定义数组
 4         $cookie_array=array(
 5            ‘shop_id‘=>$gid,
 6            ‘shop_name‘=>$shop_obj[0][‘main_title‘],
 7            ‘shop_img‘=>$shop_obj[0][‘goods_img‘],
 8            ‘shop_price‘=>$shop_obj[0][‘price‘],
 9            ‘shop_old_price‘=>$shop_obj[0][‘old_price‘]
10         );
11         #序列化数组  原因是因为cookie只能存放字符串
12         $cookie_data=serialize($cookie_array);    
13         #存入cookie
14         setcookie ( "cookie_data" ,$cookie_data ,time ()+ 3600 );
15         #取出cookie  并序列化
16         $data_info=unserialize($_COOKIE[‘cookie_data‘]);
17         var_dump($data_info);
