A simple PHP API extension for DateTime.
Carbon 使处理日期和时间更加简单。
- 处理时区
- 轻松获取时间
- 日期加减
- 使用英语短语处理时间
- ...
安装
- 使用 composer 安装，
composer require nesbot/carbon。 - 在 composer.json 里添加
{
"require": {
"nesbot/carbon": "~1.18"
}
}- 执行
composer install - 没有使用 composer
使用
获取时间
echo Carbon::now(); //当前时间
echo Carbon::yesterday(); //昨天
echo Carbon::tomorrow(); //明天以上的时间均是对象类型（使用 var_dump()）
object(Carbon\Carbon)#78 (3) { ["date"]=> string(26) "2017-11-15 00:00:00.000000" ["timezone_type"]=> int(3) ["timezone"]=> string(3) "PRC" }
需要使用 toDateTimeString() 将其转为字符串格式
var_dump(Carbon::now()->toDateTimeString());
使用一些短语获取时间
$knownDate = Carbon::create(2001, 5, 21, 12); // create testing date
Carbon::setTestNow($knownDate); // set the mock
echo new Carbon('tomorrow'); // 2001-05-22 00:00:00 ... notice the time !
echo new Carbon('yesterday'); // 2001-05-20 00:00:00
echo new Carbon('next wednesday'); // 2001-05-23 00:00:00
echo new Carbon('last friday'); // 2001-05-18 00:00:00
echo new Carbon('this thursday'); // 2001-05-24 00:00:00当使用 next(), previous() and modify() 等词语会将时分秒设置为 00:00:00
想要获取一个已知时间里的一个属性，可以这么做
$dt = Carbon::parse('2012-9-5 23:26:11.123789');
var_dump($dt->year); // int(2012)
var_dump($dt->month); // int(9)
var_dump($dt->day); // int(5)
var_dump($dt->hour); // int(23)
var_dump($dt->minute); // int(26)
var_dump($dt->second); // int(11)
var_dump($dt->micro); // int(123789)
var_dump($dt->dayOfWeek); // int(3)
var_dump($dt->dayOfYear); // int(248)
var_dump($dt->weekOfMonth); // int(1)
var_dump($dt->weekOfYear); // int(36)
var_dump($dt->daysInMonth); // int(30)
var_dump($dt->timestamp); // int(1346901971)常用时间格式
$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
echo $dt->format('l jS \\of F Y h:i:s A'); // Thursday 25th of December 1975 02:15:16 PM$dt = Carbon::now();
echo $dt->toAtomString(); // 1975-12-25T14:15:16-05:00
echo $dt->toCookieString(); // Thursday, 25-Dec-1975 14:15:16 EST
echo $dt->toIso8601String(); // 1975-12-25T14:15:16-0500
echo $dt->toRfc822String(); // Thu, 25 Dec 75 14:15:16 -0500
echo $dt->toRfc850String(); // Thursday, 25-Dec-75 14:15:16 EST
echo $dt->toRfc1036String(); // Thu, 25 Dec 75 14:15:16 -0500
echo $dt->toRfc1123String(); // Thu, 25 Dec 1975 14:15:16 -0500
echo $dt->toRfc2822String(); // Thu, 25 Dec 1975 14:15:16 -0500
echo $dt->toRfc3339String(); // 1975-12-25T14:15:16-05:00
echo $dt->toRssString(); // Thu, 25 Dec 1975 14:15:16 -0500
echo $dt->toW3cString(); // 1975-12-25T14:15:16-05:00时间比较
$first = Carbon::create(2012, 9, 5, 23, 26, 11);
$second = Carbon::create(2012, 9, 5, 20, 26, 11);
var_dump($first->eq($second)); //bool(false)
var_dump($first->ne($second)); //bool(true)
var_dump($first->gt($second)); //bool(true)
var_dump($first->gte($second)); //bool(true)
var_dump($first->lte($second)); //bool(false)还可以这样
$dt1 = Carbon::create(2012, 1, 1, 0, 0, 0);

echo $dt1->min($dt2); // 2012-01-01 00:00:00
$dt1 = Carbon::create(2012, 1, 1, 0, 0, 0);

$dt = Carbon::now();
$past = $dt->subMonth();
$future = $dt->addMonth();
echo $dt->subDays(10)->diffForHumans(); // 10 days ago
echo $dt->diffForHumans($past); // 1 month ago
echo $dt->diffForHumans($future); // 1 month before一些时间修改符
在使用这些修饰符的时候，部分时分秒会是 23:59:59,
$dt = Carbon::create(2012, 1, 31, 12, 0, 0);
echo $dt->startOfDay(); // 2012-01-31 00:00:00
$dt = Carbon::create(2012, 1, 31, 12, 0, 0);
echo $dt->endOfDay(); // 2012-01-31 23:59:59
$dt = Carbon::create(2012, 1, 31, 12, 0, 0);
echo $dt->startOfMonth(); // 2012-01-01 00:00:00
$dt = Carbon::create(2012, 1, 31, 12, 0, 0);
echo $dt->endOfMonth(); // 2012-01-31 23:59:59
$dt = Carbon::create(2012, 1, 31, 12, 0, 0);
echo $dt->startOfYear(); // 2012-01-01 00:00:00
$dt = Carbon::create(2012, 1, 31, 12, 0, 0);
echo $dt->endOfYear(); // 2012-12-31 23:59:59
$dt = Carbon::create(2012, 1, 31, 12, 0, 0);
echo $dt->startOfDecade(); // 2010-01-01 00:00:00
$dt = Carbon::create(2012, 1, 31, 12, 0, 0);
echo $dt->endOfDecade(); // 2019-12-31 23:59:59更多使用方式，参考官网
