Php datetime in range

Как получить все дни между датами в PHP

Несколько примеров как найти все дни в промежутке между двумя датами в виде значения и списка.

Количество дней между датами

$date_1 = '28.03.2022 00:00'; $date_2 = '02.04.2022 23:59'; $seconds = abs(strtotime($date_1) - strtotime($date_2)); echo round($seconds / 86400, 1); // 6

$date_1 = '28.03.2022 00:00'; $date_2 = '02.04.2022 18:00'; $seconds = abs(strtotime($date_1) - strtotime($date_2)); echo round($seconds / 86400, 1); // 5.6

Формирование массива, содержащий все дни из интервала

Первый способ – использование классов DatePeriod, DateTime и DateInterval (доступны с версии PHP 5.3).

* Если в конечной дате не указать время (23:59), то в результирующем массиве не будет последнего дня.

$period = new DatePeriod( new DateTime('28.03.2022'), new DateInterval('P1D'), new DateTime('02.04.2022 23:59') ); $dates = array(); foreach ($period as $key => $value) < $dates[] = $value->format('d.m.Y'); > print_r($dates);

Результат:

Array ( [0] => 28.03.2022 [1] => 29.03.2022 [2] => 30.03.2022 [3] => 31.03.2022 [4] => 01.04.2022 [5] => 02.04.2022 )

Функция на основе strtotime

function get_dates($start, $end, $format = 'd.m.Y') < $day = 86400; $start = strtotime($start . ' -1 days'); $end = strtotime($end . ' +1 days'); $nums = round(($end - $start) / $day); $days = array(); for ($i = 1; $i < $nums; $i++) < $days[] = date($format, ($start + ($i * $day))); >return $days; > $dates = get_dates('28.03.2022', '02.04.2022'); print_r($dates);

Результат:

Array ( [0] => 28.03.2022 [1] => 29.03.2022 [2] => 30.03.2022 [3] => 31.03.2022 [4] => 01.04.2022 [5] => 02.04.2022 )

The DatePeriod class

A date period allows iteration over a set of dates and times, recurring at regular intervals, over a given period.

Class synopsis

Predefined Constants

DatePeriod::INCLUDE_END_DATE

Properties

The minimum amount of instances as retured by the iterator.

If the number of recurrences has been explicitly passed through the recurrences parameter in the constructor of the DatePeriod instance, then this property contains this value, plus one if the start date has not been disabled through DatePeriod::EXCLUDE_START_DATE , plus one if the end date has been enabled through DatePeriod::INCLUDE_END_DATE .

If the number of recurrences has not been explicitly passed, then this property contains the minimum number of returned instances. This would be 0 , plus one if the start date has not been disabled through DatePeriod::EXCLUDE_START_DATE , plus one if the end date has been enabled through DatePeriod::INCLUDE_END_DATE .

$start = new DateTime ( ‘2018-12-31 00:00:00’ );
$end = new DateTime ( ‘2021-12-31 00:00:00’ );
$interval = new DateInterval ( ‘P1M’ );
$recurrences = 5 ;

// recurrences explicitly set through the constructor
$period = new DatePeriod ( $start , $interval , $recurrences , DatePeriod :: EXCLUDE_START_DATE );
echo $period -> recurrences , «\n» ;

$period = new DatePeriod ( $start , $interval , $recurrences );
echo $period -> recurrences , «\n» ;

$period = new DatePeriod ( $start , $interval , $recurrences , DatePeriod :: INCLUDE_END_DATE );
echo $period -> recurrences , «\n» ;

// recurrences not set in the constructor
$period = new DatePeriod ( $start , $interval , $end );
echo $period -> recurrences , «\n» ;

$period = new DatePeriod ( $start , $interval , $end , DatePeriod :: EXCLUDE_START_DATE );
echo $period -> recurrences , «\n» ;
?>

The above example will output:

Whether to include the end date in the set of recurring dates or not.

Whether to include the start date in the set of recurring dates or not.

The start date of the period.

During iteration this will contain the current date within the period.

The end date of the period.

An ISO 8601 repeating interval specification.

Changelog

Version	Description
8.2.0	The DatePeriod::INCLUDE_END_DATE constant and include_end_date property have been added.
8.0.0	DatePeriod implements IteratorAggregate now. Previously, Traversable was implemented instead.

How To Create Date Range In PHP (Simple Examples)

Welcome to a quick tutorial on how to create a date range in PHP. Need to loop through a range of dates, or generate date intervals?

1. Using DateTime, DateInterval , and DatePeriod objects.
   • $start = new DateTime(«2020-01-01»);
   • $end = new DateTime(«2020-02-02»);
   • $interval = new DateInterval(«P1D»);
   • $range = new DatePeriod($start, $interval, $end);
   • foreach ($range as $d) < echo $d->format(«Y-m-d»); >
2. Using Unix Timestamps.
   • $start = strtotime(«2020-01-01»);
   • $end = strtotime(«2020-02-01»);
   • for (let $i=$start; $i

That should cover the basics, but let us walk through more examples in this guide – Read on!

TLDR – QUICK SLIDES

TABLE OF CONTENTS

PHP DATE RANGE

All right, let us now walk through the examples on how to create a date range in PHP.

1) USING DATE-TIME OBJECTS

"; $interval = new DateInterval("P1D"); $range = new DatePeriod($start, $interval, $end); foreach ($range as $date) < echo $date->format("Y-m-d") . "
"; > // (C) WEEKLY INTERVAL - CAPTAIN OBVIOUS P7D echo "WEEKLY
"; $interval = new DateInterval("P7D"); $range = new DatePeriod($start, $interval, $end); foreach ($range as $date) < echo $date->format("Y-m-d") . "
"; > // (D) MONTHLY INTERVAL echo "MONTHLY
"; $interval = new DateInterval("P1M"); $range = new DatePeriod($start, $interval, $end); foreach ($range as $date) < echo $date->format("Y-m-d") . "
"; >

• First, define the start and end dates –
  • $start = new DateTime(«YYYY-MM-DD»)
  • $end = new DateTime(«YYYY-MM-DD»)
  • PXD Intervals of X days.
  • PXM Intervals of X months.
  • PXY Intervals of X years.

  P.S. The intervals can go down to even hours, minutes, and seconds. Will leave a link in the extras section below to the PHP manual.

  2) USING UNIX TIMESTAMPS

  "; for ($i=$start; $i"; > // (C) WEEKLY INTERVAL (1 DAY = 604800 SECONDS) echo "WEEKLY
  "; for ($i=$start; $i"; > // (D) MONTHLY INTERVAL echo "MONTHLY
  "; $i = $start; while ($i < $end) < $idate = date("Y-m-d", $i); echo $idate."
  "; $i = strtotime($idate . "+1 month"); >

  • First, get the Unix Timestamps for the start and end dates.
    • $start = strtotime(«YYYY-MM-DD»)
    • $end = strtotime(«YYYY-MM-DD»)
    • 1 day has 86400 seconds, so for a daily range – for ($i=$start; $i
    • 1 week has 604800 seconds, so for a weekly range – for ($i=$start; $i
    • Take note of the monthly range though, not all months have exactly 30 days. So the safest way to loop is to use strtotime(«YYYY-MM-DD +1 MONTH») to calculate the exact “timestamp for the next months”.
