//1、基本應(yīng)用
$now = Carbon::now();          //2016-11-03 14:13:16
$today = Carbon::today();        //2016-11-03 00:00:00
$tomorrow = Carbon::tomorrow();     //2016-11-04 00:00:00
$yesterday = Carbon::yesterday();    //2016-11-02 00:00:00

//2、判斷是否是某一天(2016-11-03（周四）舉例)
$now = Carbon::now();
var_dump($now->isWeekend());//false 因?yàn)橹芩牟皇侵苣?var_dump($now->isWeekday());//true 因?yàn)橹芩氖枪ぷ魅?var_dump($now->isThursday());//true 因?yàn)榻裉焓侵芩?$now->isToday();
$now->isTomorrow();
$now->isFuture();
$now->isPast();

//3、創(chuàng)建某一天的carbon對象并且進(jìn)行加減計(jì)算
$date = Carbon::create(2016, 12, 25, 0, 0, 0);//2016-12-25 00:00:00
$next_year=$date->addYears(2);//2018-12-25 00:00:00
$past_year=$date->subYears(2);//2014-12-25 00:00:00
$next_month=$date->addMonths(2);//2017-02-25 00:00:00
$past_month=$date->subMonths(2);//2016-10-25 00:00:00
$next_day=$date->addDays(2);//2016-12-27 00:00:00
$past_day=$date->subDays(2);//2016-12-23 00:00:00
...更有addWeekdays()、addWeeks()、addHours()等方法

//4、將carbon對象轉(zhuǎn)換成string類型
$dt = Carbon::create(1975, 12, 25, 14, 15, 16);
echo $dt->toDateString();             // 1975-12-25
echo $dt->toFormattedDateString();         // Dec 25, 1975
echo $dt->toTimeString();             // 14:15:16
echo $dt->toDateTimeString();           // 1975-12-25 14:15:16
echo $dt->toDayDateTimeString();          // Thu, Dec 25, 1975 2:15 PM
