Object of class Carbon\Carbon could not be converted to int
提问by Patrick
I have already search for this, and i did find some topics discussing this problem, however none of which I felt like was the way I want to go, so therefore I hope to get a better sugestion here.
我已经搜索过这个，我确实找到了一些讨论这个问题的话题，但是我觉得没有一个是我想要走的路，所以我希望在这里得到更好的建议。
I want to get a timestamp from when a user was last updated.
我想从用户上次更新时获取时间戳。
$user->updated_at
If i run this, it gives me this error
如果我运行它，它会给我这个错误
Object of class Carbon\Carbon could not be converted to int
This is because it returns a Carbon instance in Laravel 5.2, and I only need the timestamp.
这是因为它在 Laravel 5.2 中返回一个 Carbon 实例，而我只需要时间戳。
Carbon {#303 ▼
+"date": "2017-01-04 00:35:38.000000"
+"timezone_type": 3
+"timezone": "UTC"
}
How do i fetch the "date" from the carbon instance, so I only get 2017-01-04 00:35:38- I have no idea where .000000 comes from, as this doesn't show up in the database. In the MySQL database, it simply shows 2016-07-20 20:23:07as of type timestamp.
我如何从碳实例中获取“日期”，所以我只能得到2017-01-04 00:35:38- 我不知道 .000000 来自哪里，因为它没有出现在数据库中。在 MySQL 数据库中，它仅显示2016-07-20 20:23:07为类型timestamp。
Hope for some pointers and suggestions
希望得到一些指点和建议

The Carbonobject has a toDateTimeStringmethod you can use:
该Carbon对象有一个toDateTimeString您可以使用的方法：
$user->updated_at->toDateTimeString();
It will give you the value 2017-01-04 00:35:38as a string.
它会给你2017-01-04 00:35:38一个字符串的值。

While using Carbon library to perform multiple action using date.
使用 Carbon 库使用日期执行多个操作时。
Example :
例子 ：
Right now what you are doing.
现在你在做什么。
dd($user->updated_at);
output : Carbon {#724 ▼
+"date": "2018-06-20 18:28:48.000000"
+"timezone_type": 3
+"timezone": "UTC"
}
Suggest :
建议 ：
dd($user->updated_at->toDateTimeString());
output : 2018-06-20 18:28:48
