Preface

Everyone should know that we often use Carbon to process dates and times, right? But how many people have read the document to understand how it works? In addition to the well-known now () and format () methods, Carbon has many other useful methods.

Let's take a look.

1. isX: True/False

There are many ways to determine whether the Carbon object is today, weekend, leap year, and so on. These are listed in the official documents below:

<?php$dt->isWeekday();$dt->isWeekend();$dt->isYesterday();$dt->isToday();$dt->isTomorrow();$dt->isFuture();$dt->isPast();$dt->isLeapYear();$dt->isSameDay(Carbon::now());

2. isBirthday

In addition to the list above, Carbon also has a way to determine whether a date is a person's birthday. In addition to the single-open verification month and day, you can also do this:

$born = Carbon::createFromDate(1987, 4, 23);$noCake = Carbon::createFromDate(2014, 9, 26);$yesCake = Carbon::createFromDate(2014, 4, 23);var_dump($born->isBirthday($noCake));  // bool(false)var_dump($born->isBirthday($yesCake));

3. StartOfX and EndOfX list

The startOfX series and endOfX series are as follows:

$dt = Carbon::create(2012, 1, 31, 12, 0, 0);echo $dt->startOfDay(); // 2012-01-31 00:00:00echo $dt->endOfDay(); // 2012-01-31 23:59:59echo $dt->startOfMonth(); // 2012-01-01 00:00:00echo $dt->endOfMonth(); // 2012-01-31 23:59:59echo $dt->startOfYear(); // 2012-01-01 00:00:00echo $dt->endOfYear(); // 2012-12-31 23:59:59echo $dt->startOfDecade(); // 2010-01-01 00:00:00echo $dt->endOfDecade(); // 2019-12-31 23:59:59echo $dt->startOfCentury(); // 2000-01-01 00:00:00echo $dt->endOfCentury(); // 2099-12-31 23:59:59echo $dt->startOfWeek(); // 2012-01-30 00:00:00echo $dt->endOfWeek(); // 2012-02-05 23:59:59

4. Today, Tomorrow, Yesterday

Three simple but very useful methods: Do not call now (), replace the hour, minute, and second, and then increase or subtract the number of days:

$today = Carbon::today(); // assuming 2016-06-24echo $today;        // 2016-06-24 00:00:00$tomorrow = Carbon::tomorrow();echo $tomorrow;       // 2016-06-25 00:00:00$yesterday = Carbon::yesterday();echo $yesterday;       // 2016-06-23 00:00:00

5. DiffForHumans + Localization

You may have used this method called diffForHumans ()-It returns the difference between two dates in a way that is easier for people to read:

echo Carbon::now()->subDays(5)->diffForHumans(); // 5 days ago

But do you know it can also be localized? You only need to change the location, such as Chinese:

Carbon: setLocale ('zh '); echo Carbon: now ()-> addYear ()-> diffForHumans (); // a year ago

6. Change now () to any time you want

$ KnownDate = Carbon: create (2001, 5, 21, 12); // create the test date Carbon: setTestNow ($ knownDate); // set the mock echo Carbon :: now (); // 12:00:00

7. Week Constants

The following constant can be used to replace the day of the week:

var_dump(Carbon::SUNDAY);       // int(0)var_dump(Carbon::MONDAY);       // int(1)var_dump(Carbon::TUESDAY);       // int(2)var_dump(Carbon::WEDNESDAY);      // int(3)var_dump(Carbon::THURSDAY);      // int(4)var_dump(Carbon::FRIDAY);       // int(5)var_dump(Carbon::SATURDAY);      // int(6)
