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
...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();             // 1975-12-25
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、实例

$minutes = 1440;
$sencond = 86400;
$time = 1628303098;
 //设置中文
Carbon::setLocale('zh');
$new = new Carbon();
// 获取当前时间
Carbon::now();                                          // 2021-09-07 14:24:15
// 获取当前时间戳 
Carbon::now()->timestamp;                               // 1630995855 
//转化为时间
Carbon::parse($time);                                   // 2021-08-07 02:24:58
//转化为时间戳
Carbon::parse('2021-09-07 14:15:52')->timestamp;        // 1630995352
//分钟变天
$new->diffInDays($new->copy()->addMinutes($minutes));   // 1
//秒变天
$new->diffInDays($new->copy()->addSecond($sencond));    // 1
多久之前
Carbon::createFromTimestamp($time)->diffForHumans();    // 1个月前
