In writing PHP applications often need to deal with the date and time, carbon inherited from the PHP DateTime class API extension, which makes the processing date and time more simple, this article mainly for you to share the Laravel seven very useful but very few people know carbon method, You need a friend to refer to below.
Objective
As you all know, we use Carbon to handle dates and times in many cases, right? But how many people have read the document thoroughly to see how it has the means? In addition to the well-known now () and format () methods, Carbon has many other useful methods.
Let's take a look here.
1. Isx:true/false
There are many ways to determine whether Carbon objects are today, weekends, leap years, and so on, which are listed in the official documentation:
<?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 if a date is a person's birthday. In addition to the single-check month and day, you can also do this:
$born = Carbon::createfromdate (1987, 4,); $noCake = Carbon::createfromdate (9, +); $yesCake = Carbon:: Createfromdate, 4, Var_dump ($born->isbirthday ($noCake)); BOOL (FALSE) Var_dump ($born->isbirthday ($yesCake));
3. List of STARTOFX and ENDOFX
Below are the STARTOFX series and ENDOFX series:
$dt = carbon::create (1, 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 that do not need to call now (), then replace the seconds and minutes, 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 easy for people to read:
Echo Carbon::now ()->subdays (5)->diffforhumans (); 5 days ago
But do you know that it can also be localized? You just need to change the location, such as Chinese:
Carbon::setlocale (' zh '); echo Carbon::now ()->addyear ()->diffforhumans (); A year ago
6. Change now () for any time you want
$knownDate = Carbon::create (2001, 5, 21, 12); Create test Date Carbon::settestnow ($knownDate); Set the mock echo carbon::now (); 2001-05-21 12:00:00
7. Week constants
The following constants can be used instead of 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)
Do you know all the useful methods mentioned above? You can list the methods that you find useful in the message type.
