This small library tries to ease printing of date-ranges.

Installation

Installation is easy via composer. Simply type this in your terminal to add the DateRange-Library to your composer.conf-file:

composer require org_heigl/daterange

Usage

You can then use the DateRange library by creating a DateRange-instance, setting a format and a separator and then simply calling getDateRange() with the start-date and the end date as parameters.

Simple example:

<?php
use Org_Heigl\DateRange\DateRangeFormatter

$dateRange = new DateRangeFormatter();
$dateRange->setFormat('d.m.Y');
$dateRange->setSeparator(' - ');
echo $dateRange->getDateRange(new \DateTime('12.3.2015'), new \DateTime('13.4.2015'));
// Will print: 12.03. - 13.04.2014
echo $dateRange->getDateRange(new \DateTime('12.3.2015'), new \DateTime('13.3.2015'));
// Will print: 12. - 13.03.2014

More complex example:

<?php
use Org_Heigl\DateRange\DateRangeFormatter

$dateRange = new DateRangeFormatter();
$dateRange->setFormat('m/d/Y');
$dateRange->setSeparator(' - ');
echo $dateRange->getDateRange(new \DateTime('12.3.2015'), new \DateTime('13.3.2015'));
// Will print: 3/12/ - 3/13/2014

You want to change parts of the date-formatting string? Try the Filters.

If you want to display something like 12 - 13.03.2013 (node the missing dot after the 12) you can use the formatting-string d.m.Y and add a RemoveEverythingAfterLastDateStringFilter lik this:

<?php
use Org_Heigl\DateRange\DateRangeFormatter;
use Org_Heigl\DateRange\Filter\RemoveEverythingAfterLastDateStringFilter;

$dateRange = new DateRangeFormatter();
$dateRange->setFormat('d.m.Y');
$dateRange->setSeparator(' - ');
$dateRange->addFilter(new RemoveEverythingAfterLastDateStringFilter(), DateRangeFormatter::FILTER_FIRST_DIFF);
echo $dateRange->getDateRange(new \DateTime('12.3.2015'), new \DateTime('13.3.2015'));
// Will print: 12 - 13.03.2014

Currently the following Filters are available:

• RemoveEverythingAfterLastDateStringFilter - This filter will remove everything after the last dateformatting-character in the given date-part. So when the dateformatting-string reads d.m. it will remove everything behind the m which is the last dateformatting-character.
• TrimFilter - This filter will remove excess whitespace. It just passes the dateformatting-string through the ```trim``-function.

You can implement your own filter by simply implementing the Org_Heigl\DateRange\DateRangeFilterInterface That way evertything is possible!

You can add a filter to four different filterchains that filter different parts of the formatting string.

• DateRangeFormatter::FILTER_COMPLETE will be applied to a formatting string when first and second day are the same. So the input will be the formatting-string you provided via the DateRangeFormatter::setFormat().
• DateRangeFormatter::FILTER_FIRST_DIFF will be applied to the first part of the splitted formatting string that is used for the start-date. So when your formatting string is d.m.Y and the dates differ in the month the filter will be applied to d.m. for the starting date
• DateRangeFormatter::FILTER_SECOND_DIFF will be applied to the first part of the splitted formatting string that is used for the end-date. So when your formatting-string is d.m.Y and the dates differ in the month the filter will be applied to d.m. for the end-date
• DateRangeFormatter::FILTER_SAME will be applied to the second part of the splitted formatting string that is used for the part that is equal on start- and end-date. So when your formatting-string is d.m.Y and the dates differ in the day the filter will be applied to m.Y.
