README

DateRange is a simple representation of date range for PHP.

Requirements

DateRange works with PHP 5.4.0 or later.

Install

The recommended way to install date-range is with composer.

$ composer require brtriver/date-range

Usage

Instance

Pass two date(start and end) args like below:

use Brtriver\DateRange\DateRange;
$range = new DateRange('2015-12-01', '2015-12-31');

or Pass array of date :

$range = new DateRange(['2015-12-01', '2015-12-31']);

Not only string format but DateTime object is also accepted :

$start = new DateTime('2012-12-01');
$end = new DateTime('2012-12-31');
$range = new DateRange([$start, $end]);

Exception

if DateRange cannot accept construct parameters, it throw InvalidArgumentException. So in a short scope, you have to catch the exception.

try {
  $range = new DateRange('tomorrow', 'today');
} catch (\InvalidArgumentException $e) {
  echo $e->getMessage();
  // end date is the day before than start date
}

access two date

DateRange has 2 date as DateTime object. and you can access with getter methods.

# if you get start DateTime object.
$start = $range->getStart();

# if you get end DateTime object.
$end = $range->getEnd();

contains

## check contains specific date
var_dump($range->contains('2015-12-10'));
// bool(true)

var_dump($range->contains('2017-01-10'));
// bool(false)

diff

get DateInterval between start and end date to call diff:

$range = new DateRange('2015-12-01', '2015-12-03');
$range->diff()->format('%R%a days');
// +2 days

toString

get start and end date string to echo the instance:

$range = new DateRange('2015-12-01', '2015-12-03');
echo $range;
// '2015-12-01 ~ 2015-12-03'

If you want to change the format, to call toString method with your format and separator:

$range = new DateRange('2015-12-01', '2015-12-03');
echo $range->toString('Y/m/d', '-');
// '2015/12/01 - 2015/12/03'

Period

You can use DateRange in foreach.

foreach ($range as $d) {
    echo $d->format('Y-m-d') . PHP_EOL;
}

If you use DatePeriod object directly, you can also get DatePeriod object through getDatePeriod like below:

foreach ($range->getDatePeriod() as $d) {
    echo $d->format('Y-m-d') . PHP_EOL;
}
// 2015-12-01
// 2015-12-02
// 2015-12-03
// 2015-12-04
// ...
// 2015-12-28
// 2015-12-29
// 2015-12-30
// 2015-12-31

Default interval is set to P1D. If you want to change interval, call setInterval

## if you want to change interval, use setInterval()
$start = new DateTime('2012-12-01');
$end = new DateTime('2020-12-31');
$range = new DateRange([$start, $end]);
$range->setInterval(new DateInterval('P1Y')); // change from 'P1D' (Default)
foreach ($range->getDatePeriod() as $d) {
    echo $d->format('Y-m-d') . PHP_EOL;
}
// 2012-12-01
// 2013-12-01
// 2014-12-01
// 2015-12-01
// 2016-12-01
// 2017-12-01
// 2018-12-01
// 2019-12-01
// 2020-12-01

exclude start or end date

If you want to exclude start (end) date in range, call excludeStartDate() or excludeEndDate() like below:

// exclude start date
$range = new DateRange('2015-12-01', '2015-12-03');
$range->excludeStartDate();
foreach ($range => $d) {
    echo $d->format('Y-m-d') . PHP_EOL;
}
// 2015-12-02
// 2015-12-03

// exclude end date
$range = new DateRange('2015-12-01', '2015-12-03');
$range->excludeEndDate();
foreach ($range => $d) {
    echo $d->format('Y-m-d') . PHP_EOL;
}
// 2015-12-01
// 2015-12-02
