Intro

What is moment.php?

Date library for parsing, manipulating and formatting dates.

Any dependencies?

PHP 5.3 or later since moment.php is based on php's DateTime Class.

---

Install

Easy install via composer. Still no idea what composer is? Inform yourself here.

{
    "require": {
        "fightbulc/moment": "1.4.*"
    }
}

Quick examples

1. Get a moment

$m = new Moment(); // default is "now" UTC
echo $m->format(); // e.g. 2012-10-03T10:00:00+0000

$m = new Moment('now', 'Europe/Berlin');
echo $m->format(); // e.g. 2012-10-03T12:00:00+0200

---

2. Custom format

2.1 PHP only (Standard)

$m = new Moment('2012-04-25T03:00:00', 'CET');
echo $m->format('l, dS F Y / H:i (e)'); // Wednesday, 25th April 2012 / 03:00 (Europe/Berlin)

Formats are based on PHP's Date function and DateTime class.

2.2 Non-php formats

You can now inject different format handling by passing along a class which implements the FormatsInterface. You can find an example within the test folder for implementing all formats from moment.js. Thanks to Ashish for taking the time to match moment.js formats to those of PHP. Have a look at the test script to see the example in action.

Everybody can write format classes in the same manner. Its easy and scalable.

// get  desired formats class
// create a moment
$m = new \Moment\Moment('2012-04-25T03:00:00', 'CET');

// format with moment.js definitions
echo $m->format('LLLL', new \Moment\CustomFormats\MomentJs()); // Wednesday, April 25th 2012 3:00 AM

---

3. Switch timezones

$m = new Moment('2012-04-25T03:00:00', 'CET');
echo $m->setTimezone('UTC')->format(); // 2012-04-25T01:00:00+0000

---

4. Create a custom moment and manipulate it

$m = new Moment('2012-05-15T12:30:00', 'CET');
echo $m->addHours(2)->format(); // 2012-05-15T14:30:00+0200

$m = new Moment('2012-05-15T12:30:00', 'CET');
echo $m->subtractDays(7)->subtractMinutes(15)->format(); // 2012-05-08T12:15:00+0200

Methods for manipulating the date/time

Add	Subtract
addSeconds($s)	subtractSeconds($s)
addMinutes($s)	subtractMinutes($i)
addHours($s)	subtractHours($h)
addDays($s)	subtractDays($d)
addWeeks($w)	subtractWeeks($w)
addMonths($m)	subtractMonths($m)
addYears($y)	subtractYears($y)

---

5. Difference between dates

$m = new Moment('2013-02-01T07:00:00');
$momentFromVo = $m->fromNow();

// or from a specific moment
$m = new Moment('2013-02-01T07:00:00');
$momentFromVo = $m->from('2011-09-25T10:00:00');

// result comes as a value object class
echo $momentFromVo->getSeconds()    // -19630800
echo $momentFromVo->getMinutes()    // -327180
echo $momentFromVo->getHours()      // -5453
echo $momentFromVo->getDays()       // -227.21
echo $momentFromVo->getWeeks()      // -32.46

---

6. Get date periods (week, month)

Sometimes its helpful to get the period boundaries of a given date. For instance in case that today is Wednesday and I need the starting-/end dates from today's week. Allowed periods are week and month.

$m = new Moment('2013-10-23T10:00:00');
$momentPeriodVo = $m->getPeriod('week');

// results comes as well as a value object class
echo $momentPeriodVo
    ->getStartDate()
    ->format('Y-m-d'); // 2013-10-21

echo $momentPeriodVo
    ->getEndDate()
    ->format('Y-m-d'); // 2013-10-27

echo $momentPeriodVo
    ->getRefDate()
    ->format('Y-m-d'); // 2013-10-23

---

7. Calendar Times

Calendar time displays time relative to now, but slightly differently than Moment::fromNow(). Moment::calendar() will format a date with different strings depending on how close to today the date is.

(new \Moment\Moment('2014-03-30T16:58:00', 'CET'))->subtractDays(6)->calendar(); // last week
(new \Moment\Moment('2014-03-30T16:58:00', 'CET'))->subtractDays(1)->calendar(); // yesterday
(new \Moment\Moment('2014-03-30T16:58:00', 'CET'))->calendar(); // today
(new \Moment\Moment('2014-03-30T16:58:00', 'CET'))->addDays(1)->calendar(); // tomorrow
(new \Moment\Moment('2014-03-30T16:58:00', 'CET'))->addDays(3)->calendar(); // next week
(new \Moment\Moment('2014-03-30T16:58:00', 'CET'))->addDays(10)->calendar(); // everything else

Time	Display
Last week	Last Monday at 15:54
The day before	Yesterday at 15:54
The same day	Today at 15:54
The next day	Tomorrow at 15:54
The next week	Wednesday at 15:54
Everything else	04/09/2014

Roadmap

Useful date calculations

Get date periods by a given interval. Valid periods would be: week, month, quarter, halfyear, year.

$m = new Moment();

// Get the period for the 2nd quarter of 2012
$m->getPeriodByInterval('2012', 'quarter', 2);

// result as array
[reference] => 2012-04-01, [start] => 2012-04-01, [end] => 2012-06-30, [interval] => 2
