PHP中的日期时间处理利器实例（Carbon）

php;">//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();             // 1975-12-25echo $dt->toFormattedDateString();         // Dec 25, 1975echo $dt->toTimeString();             // 14:15:16echo $dt->toDateTimeString();           // 1975-12-25 14:15:16echo $dt->toDayDateTimeString();          // Thu, Dec 25, 1975 2:15 PM
