`DateTimeImmutable` polyfill
============================

[](#datetimeimmutable-polyfill)

[![Build Status](https://camo.githubusercontent.com/0aa540b0abd14f94463773d2445fe544698da5a61f787549255e12f986013938/68747470733a2f2f7472617669732d63692e6f72672f74686577696c6b796261726b69642f646174652d74696d652d696d6d757461626c652e706e673f6272616e63683d6d6173746572)](https://travis-ci.org/thewilkybarkid/date-time-immutable)

This small library adds a polyfill for the `DateTimeImmutable` object introduced in PHP 5.5.0.

Authors
-------

[](#authors)

- Chris Wilkinson

It's partially based on Benjamin Eberlei's [Immutable DateTime Objects](http://www.whitewashing.de/2010/01/08/immutable-datetime-objects.html) blog post.

Installation
------------

[](#installation)

```
$ php composer.phar require thewilkybarkid/date-time-immutable:~1.0

```

Basic usage
-----------

[](#basic-usage)

```
$dateTime = new DateTimeImmutable();
$newDateTime = $datetime->modify('+1 day');
var_dump($dateTime === $newDateTime); // output 'bool(false)'

```

Caveats
-------

[](#caveats)

PHP 5.5.0 also introduced a `DateTimeInterface` which both `DateTimeImmutable` and `DateTime` implement. In this polyfill we can't change the `DateTime` class, so `DateTimeImmutable` has to extend it. This is slightly dangerous as their behaviour is not compatible (see ).

PHP 5.6.0 added a `DateTimeImmutable::createFromMutable()` factory method, which this polyfill doesn't include.
