Detailed explanation of Laravel framework in php language

Laravel has won widespread attention with its simplicity and elegance. Whether experts or novices, when developing PHP projects, they will think of Laravel immediately. In this article we will discuss why Laravel has become the most successful PHP framework

In 2011, Taylor Otwell introduced Laravel to everyone as a framework that includes a new and modern approach. Laravel was originally designed for the MVC architecture, which can meet various needs such as event processing and user authentication. In addition, it has a package manager powered by a management database for managing modular and extensible code.

Laravel has won widespread attention with its simplicity and elegance. Whether experts or novices, they will think of Laravel immediately when developing PHP projects. In this article we will discuss why Laravel has become the most successful PHP framework.

Modularity and scalability

Laravel focuses on the modularity and scalability of the code. You can find any file you want to add in the Packalyst directory, which contains over 5500 packages. The goal of Laravel is to enable you to find any file you want.

Microservices and program interfaces

Lumen is a micro-framework derived from laravel that focuses on streamlining. Its high-performance programming interface allows you to develop micro-projects more easily and quickly. Lumen integrates all the important features of laravel with minimal configuration. You can migrate the complete framework by copying the code to the laravel project.

get('/', function() {return view('lumen');});$app->post('framework/{id}', function($framework) {$this->dispatch(new Energy($framework));});

HTTP path

Laravel has a fast, Efficient routing system. It allows users to relate parts of an application by typing paths into the browser.

Route::get('/', function () {return 'Hello World';});

HTTP Middleware

Applications can be protected by middleware—— The middleware handles the analysis and filtering of HTTP requests on the server. You can install middleware to authenticate registered users and avoid issues like cross-site scripting (XSS) or other security conditions.

input(&#39;age&#39;) <= 200) {return redirect(&#39;home&#39;);}return $next($request);}

Caching

Your application gets a robust caching system, By adjusting it, you can make your application load faster, which can provide your users with the best experience.

Cache::extend('mongo', function($app) {return Cache::repository(new MongoStore);});

Authentication

Security is critical. Laravel comes with local user authentication and can use the "remember" option to remember users. It also allows you to set some additional parameters, such as showing whether the user is active.

if (Auth::attempt(['email' => $email, 'password' => $password, 'active' => 1 ], $remember)) {// The user is being remembered...}

Type integration

Laravel Cashier can meet your needs to develop a payment system all needs. In addition to this, it synchronizes and integrates user authentication systems. So, you no longer need to worry about integrating your billing system into your development.

$user = User::find(1);$user->subscription('monthly')->create($creditCardToken);

Task automation

Elixir is a tool that allows us to define tasks using Gulp Laravel programming interface, we can use Elixir to define preprocessors that can streamline CSS and JavaScript.

elixir(function(mix) {mix.browserify('main.js');});

Encryption

A secure application should be able to encrypt data encryption. Using Laravel, you can enable the OpenSSL security encryption algorithm AES-256-CBC to meet all your needs. In addition, all encrypted values ​​are signed by a verification code that detects whether the encrypted information has been changed.

use Illuminate\Contracts\Encryption\DecryptException;try {$decrypted = Crypt::decrypt($encryptedValue);} catch (DecryptException $e) {//}

Event handling

The definition, recording and listening of events in the application are all Very quickly. The listen in the EventServiceProvider event contains a list of all events logged on your application.

protected $listen = ['App\Events\PodcastWasPurchased' => ['App\Listeners\EmailPurchaseConfirmation',],];

Pagination

Pagination in Laravel is very easy because it can be based on The user's browser's current page generates a series of links.

paginate(15);return view('user.index', ['users' => $users]);}}

Object Relational Graph (ORM)

Laravel contains a layer that handles databases , its object relationship diagram is called Eloquent. In addition, this object relationship diagram also applies to PostgreSQL.

$users = User::where('votes', '>', 100)->take(10)->get();foreach ($users as $user) {var_dump($user->name);}

Unit testing

The development of unit tests is a time-consuming task , but it is the key to ensuring that our application keeps working properly. PHPUnit can be used to perform unit testing in Laravel.

$users = User::where('votes', '>', 100)->take(10)->get();foreach ($users as $user) {var_dump($user->name);}

TO-DO LIST

Laravel提供在后台使用待办事项清单（to do list）处理复杂、漫长流程的选择。它可以让我们异步处理某些流程而不需要用户的持续导航。

Queue :: push ( new SendEmail ( $ message ));

为什么使用laravel。

PHP框架有许多，也有不同的优势。其实为“U图床”这个简单到不能再简单的app搭一个后台，更本就没有用框架的需求，纯粹是为了学习学习。公司项目有用laravel，有现成的使用代码在那里，我决定看代码＋看文档＋实践的学习速度比看一些视频教程来的快，而且我觉得看懂laravel，再回过头来学习TP，可能很快就能掌握了。
