 1 | # date_get_week_number() for PHP
 2 | 
 3 | [![Build Status](https://api.travis-ci.org/dVaffection/date_get_week_number.png)](https://travis-ci.org/dVaffection/date_get_week_number)
 4 | 
 5 | According to the [documentation](http://php.net/manual/en/function.date.php) for `date` function of the `W` format character
 6 | > ISO-8601 week number of year, weeks starting on Monday (added in PHP 4.1.0)
 7 | 
 8 | `date_get_week_number` amends this issue by retuning a week number of a year where the week starts on Sunday
 9 | 
10 | # Requirements
11 | **PHP >= 5.2.0** because of the `DateTime` object usage
12 | 
13 | # Usage
14 | 
15 | ```php
16 | $date = new \DateTime;
17 | $week = \date_get_week_number($date);
18 | ```
19 | 
20 | # Installation
21 | 
22 | Via composer: 
23 | ```javascript
24 | {
25 |     "require": {
26 |         "dv-affection/date_get_week_number": "~0.1"
27 |     }
28 | }
29 | ```
30 | 
31 | # Tests
32 | 
33 | ```
34 | cd date_get_week_number; phpunit;
35 | 
36 | ...
37 | OK (2 tests, 3 assertions)
38 | ```
