ecshop 商品历史浏览功能

1.第一步

/* 记录浏览历史 */
//var_dump($_COOKIE['ECS']['history']);
//array(5) { [0]=> string(2) "17" [1]=> string(2) "23" [2]=> string(2) "22" [3]=> string(2) "20" [4]=> string(2) "19" }
if (!empty($_COOKIE['ECS']['history']))
{
    $history = explode(',', $_COOKIE['ECS']['history']);
   // var_dump($history);
    array_unshift($history, $goods_id);
    $history = array_unique($history);
   // var_dump($history);
    while (count($history) >5)
    {
      
    }
     // var_dump("ECS[history]");
     // string(12) "ECS[history]"
    setcookie('ECS[history]', implode(',', $history), gmtime() + 3600 * 24 * 30);
}
else
{
    setcookie('ECS[history]', $goods_id, gmtime() + 3600 * 24 * 30);
}
