README
Render dates and date ranges in a human-readable format, including proper microformats-2 markup.
Usage
Date Range with Time
echo IndieWeb\DateFormatter::format('2013-10-08T07:00:00-07:00', '2013-10-08T17:00:00-07:00');
outputs
<time class="dt-start" datetime="2013-10-08T07:00:00-07:00"> October 8, 2013 from 7:00am </time> to <time class="dt-end" datetime="2013-10-08T17:00:00-07:00"> 5:00pm (-0700) </time>
(whitespace added for readability)
which displays in a browser as
October 8, 2013 from 7:00am to 5:00pm (-0700)
Date Range with No Time
echo IndieWeb\DateFormatter::format('2013-10-08', '2013-10-11');
outputs
<time class="dt-start" datetime="2013-10-08"> October 8 </time> - <time class="dt-end" datetime="2013-10-11"> 11, 2013 </time>
which displays in a browser as
October 8-11, 2013
Other Examples
This example shows how progressively more data is added to the output as the start and end dates have less in common with each other.
use IndieWeb\DateFormatter; echo DateFormatter::format('2013-09-03', '2013-09-08'); // September 3-8, 2013 echo DateFormatter::format('2013-09-28', '2013-10-03'); // September 28 through October 3, 2013 echo DateFormatter::format('2013-12-30', '2014-01-02'); // December 30, 2013 through January 2, 2014
Here are similar examples when the dates include times as well.
use IndieWeb\DateFormatter; echo DateFormatter::format('2013-10-08T07:00:00-07:00', '2013-10-08T17:00:00-07:00'); // October 8, 2013 from 7:00am to 5:00pm (-0700) echo DateFormatter::format('2013-10-08T07:00:00-07:00', '2013-10-10T17:00:00-07:00'); // October 8, 2013 at 7:00am until Oct 10 at 5:00pm (-0700) echo DateFormatter::format('2013-08-31T07:00:00-07:00', '2013-09-01T17:00:00-07:00'); // August 31, 2013 7:00am until September 1 at 5:00pm (-0700) echo DateFormatter::format('2013-12-31T07:00:00-07:00', '2014-01-01T17:00:00-07:00'); // December 31, 2013 7:00am until January 1, 2014 5:00pm (-0700)
Alternate Class Names
If you want the HTML to include Microformats classes other than "dt-start" and "dt-end", you can pass class names as additional parameters.
echo IndieWeb\DateFormatter::format('2013-10-08T07:00:00-0700', '2013-10-08T08:50:00-0700', 'dt-departure', 'dt-arrival');
<time class="dt-departure" datetime="2013-10-08T07:00:00-07:00"> October 8, 2013 from 7:00am </time> to <time class="dt-arrival" datetime="2013-10-08T8:50:00-07:00"> 8:50am (-0700) </time>
Tests
Please see the tests for more complete examples of different output formats.
Future Enhancements
- Optionally also display the day of the week in date range output
- Option to use short month names instead of full names
- Make the parser more tolerant of other input formats
If you see other input or output formats you would like handled, please open an Issue with a description. Bonus points if you write it as a test case:
public function testDescriptionOfWhatYoureTesting() { $this->_testEquals('Final Text Output', 'start-date', 'end-date'); }
