PHP implements the function of only scoring once for multiple logins a day based on the login time judgment.

This article mainly introduces the function of php based on login time judgment to achieve only one point for multiple logins a day. It is suitable for the points function of the membership system. It involves php time judgment and database related operation skills. Friends in need can refer to it

The example in this article describes how PHP can achieve only one point for multiple logins a day based on login time judgment. I would like to share it with you for your reference. The details are as follows:

I found a lot of cases on the Internet, and they all seemed similar. Some of them were quite complicated, so I tried it myself and how to implement this function.

To implement this function, I added a field logintime to the data table, indicating the last login time, and then compared it with the last login time using 0:00:00 of the day. If the last login time is greater than This time point indicates that you have logged in. If the last login time is less than this time point, it means you have logged in for the first time and points will be increased.

Code:

// 判断是否是一天中第一次登录
// 上一次登陆的时间
$lastLogintime = $userinfo['logintime'];
// 一天中的零时零分零秒
$today = strtotime(date('Y-m-d'));
if($lastLogintime < $today) {
  // 一天中第一次登录增加积分(关联更新)
  // 注意：使用关联更新数据的时候需要传递两次id
  $data[&#39;id&#39;] = $userinfo[&#39;id&#39;];
  $data[&#39;userinfo&#39;] = array(
    &#39;points&#39; => $userinfo[&#39;points&#39;] + C(&#39;LOGIN&#39;),
  );
  $user->relation(true)->where(array(&#39;id&#39;=>$userinfo[&#39;id&#39;]))->save($data);
}

It should be noted that the login time must also be modified:

// 更新登录时间和登录ip
$updateData = array(
  'id' => $userinfo['id'],
  'userinfo' => array(
    'logintime' => time(),
    'loginip' => getIP(),
  ),
);
$user->relation(true)->where(array('id'=>$userinfo['id']))->save($updateData);

This way this function is implemented
