位操作

二进制：（可用于用户权限操作）

eg: 010 | 011 = 011  

      011 & 101 = 001

用户状态：

    已领取新人红包：status = 1   (01)
    已支付过的用户：status = 2   (10)

public function update_user_status($user, $new_status)

{

    $new_user_status = $user['status'] | $new_status;

    if ($new_user_status != $new_status) {  //如果旧状态中没有此状态，$new_user_status会包含新旧状态一起更新

            $this->mysql()->update(['id'=>$user['id'],'status'=>$new_user_status]);

     }

     return true;

}

eg: $user['status'] = 010 ; $new_status = 001 ; $new_user_status = 011（更新数据，状态包含两种状态）

public function has_user_status($user, $status)

{

     $user['status'] = $user['status'] ?? 0;

     $user_status = $user['status'] & $status;

     return $user_status == $status;//返回true/false

}

eg: $user['status'] = 011; $status = 001;  $user_status = 001;  return true；

public function update_user_status($user, $new_status)
{
    $new_user_status = $user['status'] | $new_status;//01 10 /11
    if ($new_user_status != $user['status']) {
        return $this->mysql()->update(['status'=>$new_user_status,'id'=>$user['id']]);
    }
    return true;
}

public function has_user_status($user,$status)
{
    $user['status'] = $user['status'] ?? 0;
    $user_status = $user['status'] & $status;//11 10 /10
    return $user_status == $status;
