Use of laravel carbon time processing class

1、 Get the current time

// You can pass a valid time zone as a parameter 
echo Carbon::now();//2019-08-17 09:27:49
echo Carbon::now('America/Los_Angeles');//2019-08-17 02:27:49

2、 Get yesterday, today and tomorrow

// You can pass a valid time zone as a parameter 
echo Carbon::today();//2019-08-17 00:00:00
echo  Carbon::tomorrow('America/Los_Angeles');//2019-08-18 00:00:00
echo Carbon::yesterday();//2019-08-16 00:00:00 

3、 Convert string type

echo Carbon::today()->toDateTimeString();
echo Carbon::yesterday()->toDateTimeString();
echo Carbon::tomorrow()->toDateTimeString();

4、 Date resolution

echo Carbon::parse('2016-10-15')->toDateTimeString(); //2016-10-15 00:00:00
echo Carbon::parse('2016-10-15')->toDateTimeString(); //2016-10-15 00:00:00
echo Carbon::parse('2016-10-15 00:10:25')->toDateTimeString(); //2016-10-15 00:10:25
 
echo Carbon::parse('today')->toDateTimeString(); //2016-10-15 00:00:00
echo Carbon::parse('yesterday')->toDateTimeString(); //2016-10-14 00:00:00
echo Carbon::parse('tomorrow')->toDateTimeString(); //2016-10-16 00:00:00
echo Carbon::parse('2 days ago')->toDateTimeString(); //2016-10-13 20:49:53
echo Carbon::parse('+3 days')->toDateTimeString(); //2016-10-18 20:49:53
echo Carbon::parse('+2 weeks')->toDateTimeString(); //2016-10-29 20:49:53
echo Carbon::parse('+4 months')->toDateTimeString(); //2017-02-15 20:49:53
echo Carbon::parse('-1 year')->toDateTimeString(); //2015-10-15 20:49:53
echo Carbon::parse('next wednesday')->toDateTimeString(); //2016-10-19 00:00:00
echo Carbon::parse('last friday')->toDateTimeString(); //2016-10-14 00:00:00

5、 Construction date

$year = '2015';
$month = '04';
$day = '12';

echo Carbon::createFromDate($year, $month, $day); //2015-04-12 20:55:59
 
$hour = '02';
$minute = '15':
$second = '30';
 
echo Carbon::create($year, $month, $day, $hour, $minute, $second); //2015-04-12 02:15:30
 
echo Carbon::createFromDate(null, 12, 25);  //  Year defaults to the current year 

6、 Date operations

//add- Add  sub- reduce 
echo Carbon::now()->addDays(25); //2016-11-09 14:00:01
echo Carbon::now()->addWeeks(3); //2016-11-05 14:00:01
echo Carbon::now()->addHours(25); //2016-10-16 15:00:01
echo Carbon::now()->subHours(2); //2016-10-15 12:00:01
echo Carbon::now()->addHours(2)->addMinutes(12); //2016-10-15 16:12:01
echo Carbon::now()->modify('+15 days'); //2016-10-30 14:00:01
echo Carbon::now()->modify('-2 days'); //2016-10-13 14:00:01

7、 Date comparison

/* min – Return the minimum date . max –  Returns the maximum date . eq –  Judge whether two dates are equal . gt –  Determine whether the first date is greater than the second date . lt –  Judge whether the first date is smaller than the second date . gte –  Judge whether the first date is greater than or equal to the second date . lte –  Judge whether the first date is less than or equal to the second date . */

echo Carbon::now()->tzName;                        // America/Toronto
$first = Carbon::create(2012, 9, 5, 23, 26, 11);
$second = Carbon::create(2012, 9, 5, 20, 26, 11, 'America/Vancouver');
 
echo $first->toDateTimeString();                   // 2012-09-05 23:26:11
echo $first->tzName;                               // America/Toronto
echo $second->toDateTimeString();                  // 2012-09-05 20:26:11
echo $second->tzName;                              // America/Vancouver
 
var_dump($first->eq($second));                     // bool(true)
var_dump($first->ne($second));                     // bool(false)
var_dump($first->gt($second));                     // bool(false)
var_dump($first->gte($second));                    // bool(true)
var_dump($first->lt($second));                     // bool(false)
var_dump($first->lte($second));                    // bool(true)
 
$first->setDateTime(2012, 1, 1, 0, 0, 0);
$second->setDateTime(2012, 1, 1, 0, 0, 0);         // Remember tz is 'America/Vancouver'
 
var_dump($first->eq($second));                     // bool(false)
var_dump($first->ne($second));                     // bool(true)
var_dump($first->gt($second));                     // bool(false)
var_dump($first->gte($second));                    // bool(false)
var_dump($first->lt($second));                     // bool(true)
var_dump($first->lte($second));                    // bool(true)

8、 Determine whether a date is between two dates

$first = Carbon::create(2012, 9, 5, 1);
$second = Carbon::create(2012, 9, 5, 5);
var_dump(Carbon::create(2012, 9, 5, 3)->between($first, $second));          // bool(true)
var_dump(Carbon::create(2012, 9, 5, 5)->between($first, $second));          // bool(true)
var_dump(Carbon::create(2012, 9, 5, 5)->between($first, $second, false));   // bool(false)

9、 Auxiliary method

$dt = Carbon::now();
 
$dt->isWeekday();
$dt->isWeekend();
$dt->isYesterday();
$dt->isToday();
$dt->isTomorrow();
$dt->isFuture();
$dt->isPast();
$dt->isLeapYear();
$dt->isSameDay(Carbon::now());
$born = Carbon::createFromDate(1987, 4, 23);
$noCake = Carbon::createFromDate(2014, 9, 26);
$yesCake = Carbon::createFromDate(2014, 4, 23);
$overTheHill = Carbon::now()->subYears(50);
var_dump($born->isBirthday($noCake));              // bool(false)
var_dump($born->isBirthday($yesCake));             // bool(true)
var_dump($overTheHill->isBirthday());              // bool(true) -> default compare it to today!

10、 Turn time into a text description

echo Carbon::now()->subDays(5)->diffForHumans();               // 5 Days ago, 
echo Carbon::now()->diffForHumans(Carbon::now()->subYear());   // 1 After year 
 
$dt = Carbon::createFromDate(2011, 8, 1);
echo $dt->diffForHumans($dt->copy()->addMonth());              // 1 Month ago, 
echo $dt->diffForHumans($dt->copy()->subMonth());              // 11 After month 
 
echo Carbon::now()->addSeconds(5)->diffForHumans();            // 5 Seconds from now 

echo Carbon::now()->subDays(24)->diffForHumans();              // 3 Zhou Qian 
// You can set the second parameter to  true  To delete ' front '、' From now on ' Other modifiers 
echo Carbon::now()->subDays(24)->diffForHumans(null, true);    // 3 Zhou
