php 怎么判断给用户一天送一次金币??

session(判断用户)+数据库(当前时间是否落在上一次送金币时间决定的一天区间时间内=>当前时间是否大于上一次送金币时间决定的一天区间时间的上限,使用timestamp加加减减就好了)

如果不是非常严格 就用cookie呗 如果要严格 就建立个数据库字段 值为当天日期

在服务器端,记录送金币的时间戳,如果时间戳为当天就说明送过金币,不是就没送过。

<code>    $today = new DateTime('today');
    if(is_null($user->givedtime))
    {
        //一次都没送过
    }
    else if(strtotime($user->givedtime) >= $today->getTimestamp())
    {
        //当天送过
    }
    else {
        //当天没送过
    }
</code>
