php Laravel - 如何获得日期的年份属性

Laravel - How to get year property of date

提问by ketom

I have a "datetime" field in mysql.

我在 mysql 中有一个“日期时间”字段。

$time = "1900-01-01 00:00:00";

I cant get only year. I tried $time -> year, but its not good.

我不能只得到一年。我试过了$time -> year，但效果不好。

(Trying to get property of non-object) Maybe i need to convert this string to date?

（试图获取非对象的属性）也许我需要将此字符串转换为日期？

I hope someone can help me! Thanks so much!

我希望有一个人可以帮助我！非常感谢！

You can do this in two ways,

你可以通过两种方式做到这一点，

1 - Define the date filed in the related modelas,

1 - 定义在相关文件中提交的日期model，

public function getDates()
{
    //define the datetime table column names as below in an array, and you will get the
    //carbon objects for these fields in model objects.

    return array('created_at', 'updated_at', 'date_time_field');
}

then laravel return a carbon object for these columns, so that you can use like $time->year.

然后 Laravel 为这些列返回一个 carbon 对象，以便您可以使用 like $time->year。

2- You can create a carbon object and get the year as in Moppo's answer

2-您可以创建一个碳对象并按照 Moppo 的回答获取年份

Carbon::createFromFormat('Y-m-d H:i:s', $time)->year

First one make so clean for me, you can decide which way suits you.

第一个对我来说很干净，你可以决定哪种方式适合你。

In Laravel you can use Carbonto parse the date:

在 Laravel 中，您可以使用Carbon来解析日期：

$time = "1900-01-01 00:00:00";
$date = new Carbon( $time );   

Once you get the Carbon object, to get the year you can do:

获得 Carbon 对象后，要获得年份，您可以执行以下操作：

$date->year;

Or:

或者：

$date->format('Y');

use PHP's built in methods

使用 PHP 的内置方法

$year = date('Y', strtotime($dateString));
