PHP中的日期时间处理利器实例

//1、基本应用

$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、判断是否是某一天(2016-11-03（周四）举例)

$now= Carbon::now();

var_dump($now->isWeekend());//false 因为周四不是周末

var_dump($now->isWeekday());//true 因为周四是工作日

var_dump($now->isThursday());//true 因为今天是周四

$now->isToday();

$now->isTomorrow();

$now->isFuture();

$now->isPast();

//3、创建某一天的carbon对象并且进行加减计算

$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、将carbon对象转换成string类型

$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
