从Carbon到来的日期和指定日期获取日期？

In Carbon, I can do

Carbon::parse("This Sunday"); // This gives me coming date for Sunday

But I want to get date for day like get coming date of Sunday after 2018-01-01. Is it possible to achieve something like this?

You can achieve this simply with

Carbon::parse("2018-01-01")->modify("next Sunday");

or using next() which might be faster

Carbon::parse("2018-01-01")->next(Carbon::SUNDAY);

You could do

$sunday = Carbon::parse("This Sunday");
$sunday->next(Carbon::SUNDAY);

Docs

Yes, you can write something like this.

Carbon::parse('first sunday of January 2018')

The documentation is here http://carbon.nesbot.com/docs/

You could possibly do something like: As mentioned in the official documentation

$sunday = Carbon::parse("This Sunday"); //you are able to retrieve this currently

$nextSunday = $sunday->addWeek();
