Symfony 4 was released on November 30th.
Update now to the best Symfony ever!

Meet the bundle: MobileDetectBundle

Mobile phones are taking over the world and, by extension, the web. Aside from the growth of responsive web design, websites are increasingly designing specific versions of their sites for mobile devices.

In this article we'll introduce MobileDetectBundle, which detects mobile devices and helps you redirect users to the appropriate version of your website. Once installed, this is the only configuration you need to setup the usual scenario of redirecting mobile users to the m. host of your website:

# app/config/config.yml
mobile_detect:
    redirect:
        mobile:
            is_enabled: true
            host: http://m.example.com
            action: redirect
        detect_tablet_as_mobile: true

Read the official documentation of this bundle to learn how to configure more complex redirection scenarios.

Apart from redirecting users, this bundle also provides a mobile_detector service which allows you to detect device types, operating systems and even vendors:

 1

$device = $this->get('mobile_detect.mobile_detector');

// basic device detection
$device->isMobile();
$device->isTablet();

// fine-grained device detection
$device->isIphone();
$device->isIpad();
$device->isSamsung();

// device operating system
$device->isIOS();
$device->isAndroidOS();

All these methods are also available in your Twig templates via the equivalent functions provided by the bundle:

{% extends is_mobile() ? 'mobile/layout.html.twig': 'layout.html.twig' %}

{% if is_android_os() %}
    Download our application from the store.
{% endif %}

{% if is_device('samsung') %}
    Thinking about buying an iPhone? Check out our deals!
{% endif %}

You make my day! :D
Ever since I came across this bundle, it has been the very first bundle I install in all of my Symfony Apps.
Before I think of whether or not I want to create a community site, a blog, or anything else, I am always sure that I want a site that adopts to the specific features, needs and requirements of the browser and/or OS that is used to view it.
Looks nice, but is there any cookbook on using it for heavy-load sites behind caching proxy (e.g. Varnish)?
APYBreadcrumbTrailBundle is a nice bundle I use to manage breadcrumbs. It allows you to configure breadcrumbs through annotations for whole controller and in each action specifically. Also has Twig and PHP configuration. Before this, I had to manually define the breadcrumbs with an array in each action. Every time the route or the name of the item would change, I would have to trace every controller to make the changes. With this bundle, it's much more easier.
