cocur/human-date

Transforms dates into a human-readable format.

Features

• Transforms dates into a human-readable format
• Supports translatable strings
• No external dependencies.
• PSR-4 compatible.
• Compatible with PHP >= 5.4 and HHVM.
• Integrations for Symfony2 and Twig.

Installation

You can install cocur/human-date using Composer:

$ composer require cocur/human-date:@stable

In a production environment you should replace @stable with the version you want to use.

Usage

You can pass an instance of DateTime to the HumanDate::transform() method. For example, assuming that today is 2012-08-18:

use Cocur\HumanDate\HumanDate;

$humanDate = new HumanDate();

echo $humanDate->transform(new DateTime('now'));
// 'Today'

echo $humanDate->transform(new DateTime('+1 day'));
// 'Tomorrow'

echo $humanDate->transform(new DateTime('-1 day'));
// 'Yesterday'

echo $humanDate->transform(new DateTime('2012-08-21'));
// 'Next Tuesday'

echo $humanDate->transform(new DateTime('2012-09-30'));
// 'September 30'

echo $humanDate->transform(new DateTime('2013-03-30'));
// 'March 30, 2013'

Translation

HumanDate supports translation of strings. The Cocur\HumanDate\HumanDate constructor accepts an instance of Cocur\HumanDate\Translation\TranslationInterface.

$translation = MyTranslation(); // must implement `Cocur\HumanDate\Translation\TranslationInterface`
$humanDate = new HumanDate($translation);

echo $humanDate->transform(new DateTime('now'));
// Calls MyTranslation::trans()

Additionally the library includes an adapter for the Symfony Translation component.

Bridges

cocur/human-date contains bridges for Symfony and Twig.

Symfony

The Symfony bridge provides you with a bundle and an extension to use HumanDate as a service in your application.

# app/AppKernel.php

class AppKernel extends Kernel
{
    public function registerBundles()
    {
        $bundles = array(
            // ...
            new Cocur\HumanDate\Bridge\Symfony\CocurHumanDateBundle(),
        );
        // ...
    }

    // ...
}

You can now use the cocur_human_date service everywhere in your application, for example, in your controller:

$slug = $this->get('cocur_human_date')->slugify(new DateTime('2014-04-14'));

The bundle also provides an alias human_date for the cocur_human_date service:

$slug = $this->get('human_date')->slugify(new DateTime('2014-04-14'));

Translation

HumanDate includes an adapter for the Symfony Translation component. The adapter requires an instance of Symfony\Component\Translation\TranslatorInterface and additionally accepts a translation domain and locale. The adapters trans() method passes theses values to every call of Symfony\Component\Translation\TranslatorInterface::trans().

use Cocur\HumanDate\Bridge\Symfony\Translation\SymfonyTranslation;
use Cocur\HumanDate\HumanDate;

// Get or create an instance of Symfony\Component\Translation\TranslatorInterface
// For example, inside a controller
$sfTrans = $this->get('translation');

// Create an adapter with translation domain "human_date" and locale "en"
// trans() passes domain and locale to every call of Symfony\Component\Translation\TranslatorInterface::trans()
// If you omit the domain and locale it uses the defaults.
$trans = new SymfonyTranslation($sfTrans, 'human_date', 'en');

$humanDate = new HumanDate($trans);

Twig

If you use the Symfony2 framework with Twig you can use the Twig filter humanDate in your templates after you have setup Symfony2 integrations (see above).

{{ post.createdAt|humanDate }}

If you use Twig outside of the Symfony2 framework you first need to add the extension to your environment:

use Cocur\HumanDate\Bridge\Twig\HumanDateExtension;
use Cocur\HumanDate\HumanDate;

$twig = new Twig_Environment($loader);
$twig->addExtension(new HumanDateExtension(new HumanDate()));

You can find more information about registering extensions in the Twig documentation.
