Carbon是PHP中很人性化的时间日期处理插件。 github地址为:[https://github.com/briannesbitt/Carbon](https://github.com/briannesbitt/Carbon) ## 安装 ~~~ composer require nesbot/carbon ~~~ 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 //还有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 ~~~ 5、本地化（中文） ~~~ Carbon::setLocale('zh'); echoCarbon::now()->addYear()->diffForHumans();// 一年前 echo Carbon::now()->subDays(5)->diffForHumans(); // 5天前 echo Carbon::now()->diffForHumans(Carbon::now()->subYear()); // 1年后 $dt = Carbon::createFromDate(2011, 8, 1); echo $dt->diffForHumans($dt->copy()->addMonth()); // 1月前 echo $dt->diffForHumans($dt->copy()->subMonth()); // 11月后 echo Carbon::now()->addSeconds(5)->diffForHumans(); // 5秒距现在 echo Carbon::now()->subDays(24)->diffForHumans(); // 3周前 echo Carbon::now()->subDays(24)->diffForHumans(null, true); // 3周 ~~~
