快速切換前後日期

<?phpuse Carbon\Carbon;$now = Carbon::now();
echo $now;                               // 2015-03-26 00:36:47
$today = Carbon::today();
echo $today;                             // 2015-03-26 00:00:00
$tomorrow = Carbon::tomorrow('Europe/London');
echo $tomorrow;                          // 2015-03-27 00:00:00
$yesterday = Carbon::yesterday();
echo $yesterday;                         // 2015-03-25 00:00:00

建立特定日期的時間

<?phpuse Carbon\Carbon;$timezone = 'Asia/Taipei';// 從「年月日」建立
Carbon::createFromDate($year, $month, $day, $timezone);// 從「時分秒」建立
Carbon::createFromTime($hour, $minute, $second, $timezone);// 從完整的「年月日時分秒」建立
Carbon::create($year, $month, $day, $hour, $minute, $second, $timezone);// 從指定的格式建立
Carbon::createFromFormat($format, $time, $tz);
echo Carbon::createFromFormat('Y-m-d H', '1975-05-21 22')->toDateTimeString(); // 1975-05-21 22:00:00// 從時間戳記建立
echo Carbon::createFromTimeStamp(-1)->toDateTimeString();                        // 1969-12-31 18:59:59
echo Carbon::createFromTimeStamp(-1, 'Europe/London')->toDateTimeString();       // 1970-01-01 00:59:59
echo Carbon::createFromTimeStampUTC(-1)->toDateTimeString();                     // 1969-12-31 23:59:59

轉換日期

<?phpuse Carbon\Carbon;// 透過文字移動日期
$knownDate = Carbon::create(2001, 5, 21, 12);          // create testing date
Carbon::setTestNow($knownDate);                        // set the mock
echo new Carbon('tomorrow');                           // 2001-05-22 00:00:00  ... notice the time !
