Introduction:
In the current era of globalization, more and more Applications need to be able to adapt to the needs of different languages ??and regions. Laravel, as a popular PHP framework, provides rich functions to support application internationalization and localization. This article will introduce how to implement internationalization and localization in Laravel and provide relevant code examples.
1. What is internationalization and localization
Internationalization (Internationalization) refers to designing applications to adapt to different languages ??and cultural habits; Localization (Localization) is based on different Region or country, the application will be adapted appropriately to meet the needs of local users.
2. Language files in Laravel
In Laravel, we can use language files to achieve internationalization and localization. Language files are stored in the resources/lang
directory, and each language has a corresponding directory. For example, the en
directory stores English language files, and the zh-CN
directory stores Chinese language files.
- Create a language file
First, we need to create a language file, which can be generated by running the following command:
php artisan make:lang zh-CN
This will be done in ## A zh-CN
directory is generated in the #resources/lang directory, and a
messages.php file is generated in this directory.
- Edit language file
resources/lang/zh-CN/messages.php, we can define some language key-value pairs, such as :
return [ 'welcome' => '歡迎', 'about' => '關(guān)于我們', // ... ];We can obtain the corresponding language value through the
trans() function in the application, for example:
echo trans('messages.welcome'); // 輸出:歡迎3. Set the language of the application
- Configuration file settings
config/app.php file and you can find the
locale configuration item. We can set its value to the corresponding language code, for example
'locale' => 'zh-CN'.
- Middleware settings
php artisan make:middleware SetLocaleThen, open the
handle method of the generated
SetLocale middleware and add the following code:
public function handle($request, Closure $next) { // 獲取用戶的首選語言 $locale = $request->getPreferredLanguage(['en', 'zh-CN']); // 設(shè)置應用的語言 app()->setLocale($locale); return $next($request); }Next, open the
app/Http/Kernel.php file and add the generated middleware to the middleware group:
protected $middlewareGroups = [ // ... 'web' => [ // ... AppHttpMiddlewareSetLocale::class, ], // ... ];Now, every time the user accesses the application, The middleware will set the language of the app based on the user's preferred language. 4. Display the content according to the language file In the view file, we can use the
trans() function to display the content according to the language file. For example, we can add the following code in the
resources/views/welcome.blade.php file:
<h1>{{ trans('messages.welcome') }}</h1> <p>{{ trans('messages.about') }}</p>When the language of the application is set to
zh-CN, Users who visit the
/ path will see the "Welcome" and "About Us" content.
: notation to specify the parameters, for example:
return [ 'welcome' => '歡迎,:name', ];Then, we can use the
trans() function in the view or controller The second parameter to replace the value of the parameter, for example:
echo trans('messages.welcome', ['name' => '王小明']); // 輸出:歡迎,王小明Using dynamic parameters can achieve more flexible language output. 6. Language selection function Sometimes, we need to provide a language selection function in the application to allow users to freely switch the language of the application. In Laravel, you can use the
URL::to() method to generate a URL containing language parameters.
routes/web.php file:
Route::get('/lang/{locale}', function ($locale) { // 設(shè)置應用的語言 App::setLocale($locale); // 生成包含語言參數(shù)的URL $url = URL::to('/'); // 重定向到指定語言的路徑 return redirect($url); });Then, add a language selection link in the view file, for example:
<a href="{{ url('lang/en') }}">English</a> <a href="{{ url('lang/zh-CN') }}">中文</a>When the user clicks the corresponding link, the application will redirect to the path of the corresponding language. Conclusion: By using the internationalization and localization functions provided by Laravel, we can easily adapt the application to the needs of different languages ??and regions. This article introduces how to use language files, set the language of the application, and dynamically replace parameters and other technologies. I hope it will be helpful to you to achieve internationalization and localization in your Laravel application. The above is the relevant content about implementing internationalization and localization in Laravel. I hope it will be helpful to you.

Laravel performance optimization can improve application efficiency through four core directions. 1. Use the cache mechanism to reduce duplicate queries, store infrequently changing data through Cache::remember() and other methods to reduce database access frequency; 2. Optimize database from the model to query statements, avoid N 1 queries, specifying field queries, adding indexes, paging processing and reading and writing separation, and reduce bottlenecks; 3. Use time-consuming operations such as email sending and file exporting to queue asynchronous processing, use Supervisor to manage workers and set up retry mechanisms; 4. Use middleware and service providers reasonably to avoid complex logic and unnecessary initialization code, and delay loading of services to improve startup efficiency.

LaravelSanctum is suitable for simple, lightweight API certifications such as SPA or mobile applications, while Passport is suitable for scenarios where full OAuth2 functionality is required. 1. Sanctum provides token-based authentication, suitable for first-party clients; 2. Passport supports complex processes such as authorization codes and client credentials, suitable for third-party developers to access; 3. Sanctum installation and configuration are simpler and maintenance costs are low; 4. Passport functions are comprehensive but configuration is complex, suitable for platforms that require fine permission control. When selecting, you should determine whether the OAuth2 feature is required based on the project requirements.

Methods to manage database state in Laravel tests include using RefreshDatabase, selective seeding of data, careful use of transactions, and manual cleaning if necessary. 1. Use RefreshDatabasetrait to automatically migrate the database structure to ensure that each test is based on a clean database; 2. Use specific seeds to fill the necessary data and generate dynamic data in combination with the model factory; 3. Use DatabaseTransactionstrait to roll back the test changes, but pay attention to its limitations; 4. Manually truncate the table or reseed the database when it cannot be automatically cleaned. These methods are flexibly selected according to the type of test and environment to ensure the reliability and efficiency of the test.

Laravel simplifies database transaction processing with built-in support. 1. Use the DB::transaction() method to automatically commit or rollback operations to ensure data integrity; 2. Support nested transactions and implement them through savepoints, but it is usually recommended to use a single transaction wrapper to avoid complexity; 3. Provide manual control methods such as beginTransaction(), commit() and rollBack(), suitable for scenarios that require more flexible processing; 4. Best practices include keeping transactions short, only using them when necessary, testing failures, and recording rollback information. Rationally choosing transaction management methods can help improve application reliability and performance.

The core of handling HTTP requests and responses in Laravel is to master the acquisition of request data, response return and file upload. 1. When receiving request data, you can inject the Request instance through type prompts and use input() or magic methods to obtain fields, and combine validate() or form request classes for verification; 2. Return response supports strings, views, JSON, responses with status codes and headers and redirect operations; 3. When processing file uploads, you need to use the file() method and store() to store files. Before uploading, you should verify the file type and size, and the storage path can be saved to the database.

The most common way to generate a named route in Laravel is to use the route() helper function, which automatically matches the path based on the route name and handles parameter binding. 1. Pass the route name and parameters in the controller or view, such as route('user.profile',['id'=>1]); 2. When multiple parameters, you only need to pass the array, and the order does not affect the matching, such as route('user.post.show',['id'=>1,'postId'=>10]); 3. Links can be directly embedded in the Blade template, such as viewing information; 4. When optional parameters are not provided, they are not displayed, such as route('user.post',

Laravel's queue priority is controlled through the startup sequence. The specific steps are: 1. Define multiple queues in the configuration file; 2. Specify the queue priority when starting a worker, such as phpartisanqueue:work--queue=high,default; 3. Use the onQueue() method to specify the queue name when distributing tasks; 4. Use LaravelHorizon and other tools to monitor and manage queue performance. This ensures that high-priority tasks are processed first while maintaining code maintainability and system stability.
