morilog/jalali
======
- Jalali calendar is a solar calendar that was used in Persia, variants of which today are still in use in Iran as well as Afghanistan. [Read more on Wikipedia](http://en.wikipedia.org/wiki/Jalali_calendar) or see [Calendar Converter](http://www.fourmilab.ch/documents/calendar/).

- Calendar conversion is based on the [algorithm provided by Kazimierz M. Borkowski](http://www.astro.uni.torun.pl/~kb/Papers/EMP/PersianC-EMP.htm) and has a very good performance.

- CalendarUtils class was ported from [jalaali/jalaali-js](https://github.com/jalaali/jalaali-js)

## Version 3 features
- High human readable API
- DateTime manipulating API
- DateTime comparing API
- Immutable

## Installation Version 3.*
> If you are using version <= 2.*, please read [old docs](https://github.com/morilog/jalali/blob/v2.3.0/README.md)
#### Requirements:
- `php >= 7.0`

Run the Composer update command

    $ composer require morilog/jalali:3.*

<a name="basic-usage"></a>
## Basic Usage
In the current version, I introduced `Jalalian` class for manipulating Jalali date time
### Jalalian
In version >= 1.1,  you can use `jdate()` instead of `Jalalian::forge()`;
#### `now([$timestamp = null])`
``` php
// the default timestamp is Now
$date = \Morilog\Jalali\Jalalian::now()
// OR
$date = jdate();

// pass timestamps
$date = Jalalian::forge(1333857600);
// OR
$date = jdate(1333857600);

// pass human readable strings to make timestamps
$date = Jalalian::forge('last sunday');

// get the timestamp
$date = Jalalian::forge('last sunday')->getTimestamp(); // 1333857600

// format the timestamp
$date = Jalalian::forge('last sunday')->format('%B %d، %Y'); // دی 02، 1391
$date = Jalalian::forge('today')->format('%A, %d %B %y'); // جمعه، 23 اسفند 97

// get a predefined format
$date = Jalalian::forge('last sunday')->format('datetime'); // 1391-10-02 00:00:00
$date = Jalalian::forge('last sunday')->format('date'); // 1391-10-02
$date = Jalalian::forge('last sunday')->format('time'); // 00:00:00

// get relative 'ago' format
$date = Jalalian::forge('now - 10 minutes')->ago() // 10 دقیقه پیش
```

### CalendarUtils
---


#### `checkDate($year, $month, $day, [$isJalali = true])`
```php
// Check jalali date
\Morilog\Jalali\CalendarUtils::checkDate(1391, 2, 30, true); // true

// Check jalali date
\Morilog\Jalali\CalendarUtils::checkDate(2016, 5, 7); // false

// Check gregorian date
\Morilog\Jalali\CalendarUtils::checkDate(2016, 5, 7, false); // true
```
---
#### `toJalali($gYear, $gMonth, $gDay)`
```php
\Morilog\Jalali\CalendarUtils::toJalali(2016, 5, 7); // [1395, 2, 18]
```
---
#### `toGregorian($jYear, $jMonth, $jDay)`
```php
\Morilog\Jalali\CalendarUtils::toGregorian(1395, 2, 18); // [2016, 5, 7]
```
---
#### `strftime($format, [$timestamp = false, $timezone = null])`
```php
CalendarUtils::strftime('Y-m-d', strtotime('2016-05-8')); // 1395-02-19
```
---
#### `createDateTimeFromFormat($format, $jalaiTimeString)`
```php
$Jalalian = '1394/11/25 15:00:00';

// get instance of \DateTime
$dateTime = \Morilog\Jalali\CalendarUtils::createDatetimeFromFormat('Y/m/d H:i:s', $Jalalian);

```
---
#### `createCarbonFromFormat($format, $jalaiTimeString)`
```php
$Jalalian = '1394/11/25 15:00:00';

// get instance of \Carbon\Carbon
$carbon = \Morilog\Jalali\CalendarUtils::createCarbonFromFormat('Y/m/d H:i:s', $Jalalian);

```
---
#### `convertNumbers($string)`
```php
// convert latin to persian
$date = \Morilog\Jalali\CalendarUtils::strftime('Y-m-d', strtotime('2016-05-8')); // 1395-02-19
\Morilog\Jalali\CalendarUtils::convertNumbers($date); // ۱۳۹۵-۰۲-۱۹

// convert persian to latin
$dateString = \Morilog\Jalali\CalendarUtils::convertNumbers('۱۳۹۵-۰۲-۱۹', true); // 1395-02-19
\Morilog\Jalali\CalendarUtils::createCarbonFromFormat('Y-m-d', $dateString)->format('Y-m-d'); //2016-05-8
```

---
#### `Carbon api-difference`

You can convert date/time to [briannesbitt/carbon](https://github.com/briannesbitt/carbon), thus being able to use it's [API](https://carbon.nesbot.com/docs/) to work with PHP DateTime class. 

##### [Difference](https://carbon.nesbot.com/docs/#api-difference) in months:

```php
// convert persian to Carbon
$date = \Morilog\Jalali\Jalalian::fromFormat('Y-m-d', "1395-02-19")->toCarbon(); 
// ->toString() => Sun May 08 2016 00:00:00 GMT+0000

// Add 4 months to Carbon
$dateAdd4Months = $date->addMonths(4);

// Difference in months
$dateAdd4Months->DiffInMonths($date); //4
$dateAdd4Months->floatDiffInMonths($date); //4.0
```

---
## Formatting ##

For help in building your formats, checkout the [PHP strftime() docs](http://php.net/manual/en/function.strftime.php).

## Notes ##

The class relies on ``strtotime()`` to make sense of your strings, and ``strftime()`` to handle the formatting. Always check the ``time()`` output to see if you get false timestamps, it which case, means the class couldn't understand what you were asking it to do.
