PHP 5.3+ 中的 DateTime 進行擴展的 PHP 庫：Carbon

Carbon 是對 PHP 5.3+ 中的 DateTime 進行擴展的 PHP 庫。

示例代碼：

printf("Right now is %s", Carbon::now()->toDateTimeString());
printf("Right now in Vancouver is %s", Carbon::now('America/Vancouver'));  //implicit __toString()
$tomorrow = Carbon::now()->addDay();
$lastWeek = Carbon::now()->subWeek();
$nextSummerOlympics = Carbon::createFromDate(2012)->addYears(4);

$officialDate = Carbon::now()->toRFC2822String();

$howOldAmI = Carbon::createFromDate(1975, 5, 21)->age;

$noonTodayLondonTime = Carbon::createFromTime(12, 0, 0, 'Europe/London');

$worldWillEnd = Carbon::createFromDate(2012, 12, 21, 'GMT');

// Don't really want to die so mock now
Carbon::setTestNow(Carbon::createFromDate(2000, 1, 1));

// comparisons are always done in UTC
if (Carbon::now()->gte($worldWillEnd)) {
   die();
}

// Phew! Return to normal behaviour
Carbon::setTestNow();

if (Carbon::now()->isWeekend()) {
   echo 'Party!';
}
echo Carbon::now()->subMinutes(2)->diffForHumans(); // '2 minutes ago'

// ... but also does 'from now', 'after' and 'before'
// rolling up to seconds, minutes, hours, days, months, years

$daysSinceEpoch = Carbon::createFromTimeStamp(0)->diffInDays();
