This article mainly introduces "what are the advantages of Laravel, the development framework of PHP". In the daily operation, I believe that many people have doubts about the advantages of Laravel, the development framework of PHP. The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the doubts of "what are the advantages of Laravel, the development framework of PHP?" Next, please follow the editor to study!

The main technical features of Laravel:

1. Bundle is the organizational form or name of the expansion package of Laravel. Laravel's expansion pack repository is quite mature and can easily help you install expansion packs (bundle) into your applications. You can choose to download an expansion pack (bundle) and copy it to the bundles directory, or install it automatically through the command line tool "Artisan".

2. There is a set of advanced PHP ActiveRecord implementation-Eloquent ORM in Laravel. It can easily apply "constraints" to both parties of the relationship, so that you have complete control over the data and enjoy all the conveniences of ActiveRecord. Eloquent natively supports all methods of querying constructors (query-builder) in Fluent.

3. Application logic (Application Logic) can be implemented in the controller (controllers) or directly integrated into the routing (route) declaration, and the syntax is similar to the Sinatra framework. Laravel's design philosophy is to give developers maximum flexibility to create both very small websites and large enterprise applications.

4. Reverse routing (Reverse Routing) gives you the ability to create a link (URI) by routing (routes) name. Just use the route name (route name) and Laravel will automatically create the correct URI for you. In this way, you can change your routes at any time, and Laravel will automatically update all relevant links for you.

5. Restful controller (Restful Controllers) is an optional way to distinguish between GET and POST request logic. For example, in a user login logic, you declare a get_login () action to handle the service of getting the landing page, and also declare a post_login () action (action) to verify the data from the form POST, and after verification, make the decision to redirect to the landing page or to the console.

6. Class Auto-loading simplifies the loading of classes (class), so that you don't have to maintain the automatic loading configuration table and non-essential component loading work. When you want to load any library (library) or model (model), just use it immediately. Laravel will automatically load the files you need.

View assembler (View Composers) is essentially a piece of code that is automatically executed when the view (View) loads. The best example is the side random article recommendation in the blog. "View assembler" includes the logic of loading random article recommendation, so that you only need to load the view (view) of the content area, and Laravel will do everything else for you.

8. Reverse Control Container (IoC container) provides a convenient way to generate new objects, instantiate objects at any time, and access singleton (singleton) objects. Reverse control (IoC) means that you can access these objects anywhere in your code without having to load external libraries (libraries), and you don't have to put up with cumbersome and redundant code structures.

9. Migrations is like a version control (version control) tool, but it manages the database paradigm and is directly integrated into Laravel. You can use the "Artisan" command line tool to generate and execute "migration" instructions. When your team members change the database paradigm, you can easily update the current project through the version control tool, and then execute the "migrate" directive. Well, your database is up-to-date!

Unit testing (Unit-Testing) is a very important part of Laravel. Laravel itself contains hundreds of test cases to ensure that changes in any one part will not affect the functionality of other parts, which is one of the reasons why Laravel is considered the most stable version in the industry. Laravel also provides convenient features that make it easy for your own code to unit test. All test cases can be run through the Artisan command line tool.

Automatic paging (Automatic Pagination) feature avoids mixing a large amount of extraneous paging configuration code into your business logic. Convenient is not to remember the current page, as long as the total number of entries from the database, and then use limit/offset to get the selected data, and finally call the 'paginate' method, let Laravel output each page link to the specified view (View), Laravel will automatically complete all the work for you. Laravel's automatic paging system is designed to be easy to implement and easy to modify. Although Laravel can handle this work automatically, don't forget to call the appropriate methods and manually configure the paging system!

Here are some small examples to illustrate:

Microservice and program interface

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