如何在 Laravel 中使用 Carbon 获得时间差

Question

我想得到现在和我从数据库中获取的 subscription_endtime 之间的时间差。我正在使用以下代码

    $subscription_endtime = DB::table('subscriptions')->where('user_id', $user_id)->value('subscription_endtime');
    $today = Carbon::now();
    $totalDuration = $subscription_endtime->diffInSeconds($today);
    return $totalDuration;

我收到以下错误

"Call to a member function diffInSeconds() on string".

如何解决这个错误？

Answer 1

看起来 subscription_endtime 不是碳物体。你可以从 Carbon

解析它

$subscription_endtime = DB::table('subscriptions')->where('user_id', $user_id)->value('subscription_endtime');
$subscription_endtime = Carbon::parse($subscription_endtime); // add this line
$today = Carbon::now();
$totalDuration = $subscription_endtime->diffInSeconds($today);
return $totalDuration;

Answer 2

$today = Carbon::now(); //returns todays date and time at this particular second
$from = \Carbon\Carbon::createFromFormat('Y-m-d H:s:i', $subscription_endtime);//returns the time fetched from the database as a Carbon Object

$diff_in_seconds = $today->diffInSeconds($from);//returns the difference between $today and $from in seconds
print_r($diff_in_seconds );//prints the difference
