Desktop And Mobile User Agent Parser

The jenssegers-agent package is a desktop/mobile user agent parser with support for Laravel, based on MobileDetect. You can use this package in any PHP application, and it also provides a Laravel service provider, giving you a service Facade:

use Jenssegers\Agent\Facades\Agent;

Agent::is('Firefox');
Agent::is('iPhone');

// Magic methods
Agent::isFirefox();
Agent::isIPhone();

// Device type
Agent::isDesktop();
Agent::isMobile();
Agent::isTablet();
Agent::isPhone();

Besides user agent helpers, the Agent service provides a language helper, device name method, platform, and more. For example, you could get the accepted browser languages using the following method:

Agent::languages(); // ['en-us', 'en']

Using the languages method, you could set the locale during a request in a middleware. Here's a simple example just to illustrate just off the top of my head:

public function handle(Request $request, Closure $next): Response
{
    $supported_locales = ['en', 'es'];
    $user_locales = Agent::languages();

    foreach ($user_locales as $locale) {
        if (in_array($locale, $supported_locales)) {
            app()->setLocale($locale);
        }
    }
    return $next($request);
}

If you do not support the locale, the config('app.fallback_locale') setting will define the locale. You might also use the languages() method in middleware to redirect a locale-specific route prefix /{locale}/ based on the user agent's supported language.

Route::prefix('/{locale}')->group(function () {
    // ...
})->whereIn('locale', ['en', 'es']);

The Agent service can also determine if the current user agent is a bot and what type of bot:

// Is the user a bot?
Agent::isRobot(); // bool

// get the robot name
Agent::robot();

Lastly, to get the device name, platform, and browser, you can use the aptly named methods on the facade:

Agent::device(); // "Macintosh"
Agent::platform(); // "OS X"
Agent::browser(); // "Safari"
