How does the laravel directory appear?

In the Laravel framework, the directory structure is very important. It ensures that the project has a clear organizational structure and is easy to understand and maintain. If you are new to Laravel, you may be confused - how do these directories appear? In this article, we will explain the origin of Laravel directories and explore the functions and roles of each directory.

Laravel’s directory structure was designed by Taylor Otwell (the founder of Laravel). Otwell started developing using the PHP language many years ago. At that time, his project code was scattered in many directories and files, making project management and maintenance difficult. Therefore, he set out to design a more reasonable directory structure to make it easier to organize and manage projects.

In the Laravel 3.x version, the directory structure originally adopted by Otwell included the following directories:

• application: the core directory of the application, including all controllers and models , views and other libraries.
• bundles: This directory is used to implement modular architecture. It allows developers to organize different functional modules together to facilitate management and maintenance.
• public: This directory contains the front-end entry file index.php and assets folder (i.e. static resource folder). These files and directories are open to the outside world and can be directly accessed by web servers such as nginx and apache.
• storage: Storage directory, used to store cache files, log files, uploaded files, etc.
• tests: Test directory, used for writing unit tests and functional tests.

However, in Laravel 4.x, Otwell has further improved the directory structure and added more directories to meet a wider range of needs. The latest Laravel directory structure contains the following directories:

• app: The core directory of the application, containing all controllers, models, views, command line scripts and other class libraries.
• bootstrap: Startup directory, including Laravel startup scripts, such as autoload.php (registering autoloading classes), app.php (initializing applications) and cache (cache directory) and other files.
• config: Configuration file directory, which contains all configuration files needed to run the application, such as session.php (used to define Session configuration), cache.php (cache configuration), etc.
• database: Database directory, including database migration files, database seed files and Eloquent model files.
• public: This directory contains the entry file index.php and the assets folder, which is open to the outside world and can be directly accessed by web servers such as nginx and apache.
• resources: Resource directory, including all resource files used by the application, such as view files, language files, CSS files, JS files, etc.
• routes: The routing directory contains the routing definitions of all applications, such as web.php (used to define website routing), api.php (used to define API routing), etc.
• storage: Storage directory, used to store cache files, log files, uploaded files, etc.
• tests: Test directory, used for writing unit tests and functional tests.
• vendor: Third-party package directory, used to store all composer packages, including Laravel's own and external ones.

The above is the directory structure of Laravel. Each directory has its specific functions and effects. In actual development, developers can organize and manage these directories as needed to achieve optimal results.

In short, Laravel's directory structure is designed to facilitate developers to organize and manage projects. By using Laravel's directory structure, developers can easily locate specific files and classes and develop applications faster. If you are new to Laravel, it is recommended that you carefully understand the usage and role of these directories, which will make your development easier.
