PHP Carbon“month()”方法生成错误的DateTime [英] PHP Carbon "month()" method generates wrong DateTime
问题描述
我使用以下代码为2016年9月初创建一个DateTime字符串:
Carbon :: create() - >月(9)
如果我使用Laravel的dd()函数输出,我收到以下输出:
Carbon\Carbon {
+date:2016-10-01 10:22:36.000000
+timezone_type:3
+timezone:欧洲/维也纳
}
它将返回10月1日,而不是9月1日!每隔一个月就可以正常工作。
我也试过这些:
Carbon :: now() - >月(9)
(新碳) - >月(9)
但是我得到的错误结果也是一样。
有没有人会遇到这个错误,有人可以尝试一下,告诉我,如果你收到相同的输出?或者我只是做错了事情,即使我不能想到任何东西?
提前感谢
我猜这个问题是今天是31日。
Carbon :: create() - > month(9)
试图在9月份的同一天。由于9月份没有31日,10月1日返回。尝试:
Carbon :: create() - > day(1) - > month(9);
或
Carbon :: create() - > startOfMonth() - > month(9);
或
Carbon :: create(null,9);
I just stumbled upon something really weird. I use the "Carbon" package to generate DateTime objects.
I use the following code to create a DateTime string for the beginning of September 2016:
Carbon::create()->month(9)
If I output this using Laravel's "dd()" function, I receive the following output:
Carbon\Carbon {
+"date": "2016-10-01 10:22:36.000000"
+"timezone_type": 3
+"timezone": "Europe/Vienna"
}
It returns the 1st of October, rather than the 1st of September! It works fine with every other month.
Ive also tried these:
Carbon::now()->month(9)
(new Carbon)->month(9)
But I get the same wrong result.
Does anyone else experience this bug or can someone please try this out and tell me if you receive the same output? Or am I just doing something wrong, even though I can't think of anything?
Thanks in advance.
I guess that the problem is todays date which is the 31st.
Carbon::create()->month(9)
tries to take the same day for September. Since there is no 31st in September, it returns October 1st. Try:
Carbon::create()->day(1)->month(9);
Or
Carbon::create()->startOfMonth()->month(9);
Or
Carbon::create(null, 9);
