转换为unix时间戳使在php中计算日期更容易:

$startTime = strtotime( '2010-05-01 12:00' );
$endTime = strtotime( '2010-05-10 12:00' );

// Loop between timestamps, 24 hours at a time
for ( $i = $startTime; $i <= $endTime; $i = $i + 86400 ) {
  $thisDate = date( 'Y-m-d', $i ); // 2010-05-01, 2010-05-02, etc
}

当使用带有夏令时的时区时，请确保添加的时间不是23:00、00:00或1:00，以防止跳过或重复日期。

$startTime = strtotime('2010-05-01'); 
$endTime = strtotime('2010-05-10'); 

// Loop between timestamps, 1 day at a time 
$i = 1;
do {
   $newTime = strtotime('+'.$i++.' days',$startTime); 
   echo $newTime;
} while ($newTime < $endTime);

or

$startTime = strtotime('2010-05-01'); 
$endTime = strtotime('2010-05-10'); 

// Loop between timestamps, 1 day at a time 
do {
   $startTime = strtotime('+1 day',$startTime); 
   echo $startTime;
} while ($startTime < $endTime);

$begin = new DateTime('2010-05-01');
$end = new DateTime('2010-05-10');

$interval = DateInterval::createFromDateString('1 day');
$period = new DatePeriod($begin, $interval, $end);

foreach ($period as $dt) {
    echo $dt->format("l Y-m-d H:i:s\n");
}

这将输出在$start和$end之间定义的时间段内的所有天数。如果你想包括10号，将$end设置为11号。你可以根据自己的喜好调整格式。请参阅DatePeriod的PHP手册。它需要PHP 5.3。

用户本功能:-

function dateRange($first, $last, $step = '+1 day', $format = 'Y-m-d' ) {
                $dates = array();
                $current = strtotime($first);
                $last = strtotime($last);

                while( $current <= $last ) {    
                    $dates[] = date($format, $current);
                    $current = strtotime($step, $current);
                }
                return $dates;
        }

使用/函数调用:-

增加一天:-

dateRange($start, $end); //increment is set to 1 day.

按月递增:-

dateRange($start, $end, "+1 month");//increase by one month

如果你想设置日期格式，可以使用第三个参数:-

   dateRange($start, $end, "+1 month", "Y-m-d H:i:s");//increase by one month and format is mysql datetime

这也包括最后的日期

$begin = new DateTime( "2015-07-03" );
$end   = new DateTime( "2015-07-09" );

for($i = $begin; $i <= $end; $i->modify('+1 day')){
    echo $i->format("Y-m-d");
}

如果你不需要最后的日期，只需从条件中删除=。

这里有一个方法:

 $date = new Carbon();
 $dtStart = $date->startOfMonth();
 $dtEnd = $dtStart->copy()->endOfMonth();

 $weekendsInMoth = [];
 while ($dtStart->diffInDays($dtEnd)) {

     if($dtStart->isWeekend()) {
            $weekendsInMoth[] = $dtStart->copy();
     }

     $dtStart->addDay();
 }

$weekendsInMoth的结果是周末天数的数组!

复制从php.net样本包括范围:

$begin = new DateTime( '2012-08-01' );
$end = new DateTime( '2012-08-31' );
$end = $end->modify( '+1 day' ); 

$interval = new DateInterval('P1D');
$daterange = new DatePeriod($begin, $interval ,$end);

foreach($daterange as $date){
    echo $date->format("Ymd") . "<br>";
}

下面是另一个简单的实现

/**
 * Date range
 *
 * @param $first
 * @param $last
 * @param string $step
 * @param string $format
 * @return array
 */
function dateRange( $first, $last, $step = '+1 day', $format = 'Y-m-d' ) {
    $dates = [];
    $current = strtotime( $first );
    $last = strtotime( $last );

    while( $current <= $last ) {

        $dates[] = date( $format, $current );
        $current = strtotime( $step, $current );
    }

    return $dates;
}

例子:

print_r( dateRange( '2010-07-26', '2010-08-05') );

Array (
    [0] => 2010-07-26
    [1] => 2010-07-27
    [2] => 2010-07-28
    [3] => 2010-07-29
    [4] => 2010-07-30
    [5] => 2010-07-31
    [6] => 2010-08-01
    [7] => 2010-08-02
    [8] => 2010-08-03
    [9] => 2010-08-04
    [10] => 2010-08-05
)

$date = new DateTime($_POST['date']);
$endDate = date_add(new DateTime($_POST['date']),date_interval_create_from_date_string("7 days"));

while ($date <= $endDate) {
    print date_format($date,'d-m-Y')." AND END DATE IS : ".date_format($endDate,'d-m-Y')."\n";
    date_add($date,date_interval_create_from_date_string("1 days"));
}

你也可以这样迭代，$_POST['date']可以从你的应用程序或网站凹痕 而不是$_POST['date']你也可以把你的字符串放在这里"21-12-2019"。两者都可以。

如果你使用Laravel并且想要使用Carbon，正确的解决方案如下:

$start_date = Carbon::createFromFormat('Y-m-d', '2020-01-01');
$end_date = Carbon::createFromFormat('Y-m-d', '2020-01-31');

$period = new CarbonPeriod($start_date, '1 day', $end_date);

foreach ($period as $dt) {
 echo $dt->format("l Y-m-d H:i:s\n");
}

记得加上:

使用碳\碳; 使用碳\ CarbonPeriod;

<?php

    $start_date = '2015-01-01';
    $end_date = '2015-06-30';

    while (strtotime($start_date) <= strtotime($end_date)) {
        echo "$start_daten";
        $start_date = date ("Y-m-d", strtotime("+1 days", strtotime($start_date)));
    }

?>

针对碳使用者

use Carbon\Carbon;

$startDay = Carbon::parse("2021-08-01");
$endDay= Carbon::parse("2021-08-05");
$period = $startDay->range($endDay, 1, 'day');

当我打印数据时

[
     Carbon\Carbon @1627790400 {#4970
       date: 2021-08-01 00:00:00.0 America/Toronto (-04:00),
     },
     Carbon\Carbon @1627876800 {#4974
       date: 2021-08-02 00:00:00.0 America/Toronto (-04:00),
     },
     Carbon\Carbon @1627963200 {#4978
       date: 2021-08-03 00:00:00.0 America/Toronto (-04:00),
     },
     Carbon\Carbon @1628049600 {#5007
       date: 2021-08-04 00:00:00.0 America/Toronto (-04:00),
     },
     Carbon\Carbon @1628136000 {#5009
       date: 2021-08-05 00:00:00.0 America/Toronto (-04:00),
     },
]

这是Laravel数据转储使用dd($period->toArray());如果您愿意，现在可以使用foreach语句遍历$period。

一个重要的注意事项-它包括提供给方法的边缘日期。

想要了解更多与约会相关的东西，请查看Carbon文档。

如果你使用的是低于8.2版本的php，并且没有DatePeriod::INCLUDE_END_DATE const。我写了一个返回\DateTimeImmutable数组的方法。

这适用于开始日期在结束日期之前、相同或之后的情况。

    /**
     * @param DateTimeImmutable $start
     * @param DateTimeImmutable $end
     * @return array<\DateTimeImmutable>
     */
    public static function getRangeDays(\DateTimeImmutable $start, \DateTimeImmutable $end): array
    {
        $startDate = $start;
        $endDate = $end;
        $forwards = $endDate >= $startDate;
        $carryDate = $startDate;
        $days = [];
        while (true) {
            if (($forwards && $carryDate > $end) || (!$forwards && $carryDate < $end)) {
                break;
            }
            $days[] = $carryDate;

            if ($forwards) {
                $carryDate = $carryDate->modify('+1 day');
            } else {
                $carryDate = $carryDate->modify('- 1 day');
            }
        }

        return $days;
    }
