Structure for a PHP web application here. Let me break it down:

1. **app/**: This directory typically contains your application code. You have subdirectories for Controllers, Models, and Views.

    - **Controllers/**: This is where your application's controller classes reside. Controllers handle the incoming requests, process them, and respond with the appropriate view or data.
    - **Models/**: This directory holds your application's model classes. Models represent your application's data structures, interact with the database, and contain business logic.
    - **Views/**: Here, you have individual PHP files for different views of your application. Views are responsible for presenting data to users.

2. **config/**: This directory holds configuration files for your application. It contains files like `database.php`, which likely contains database connection settings, and `config.php`, which may contain other application configurations.

3. **database/**: This directory is usually for database-related files. You might find migration files here, which are scripts to manage database schema changes.

4. **public/**: This directory is the document root of your web server. It contains files accessible to the public. `index.php` is often the entry point for your application. The `assets/` directory typically holds static files like CSS, JavaScript, and images.

5. **routes/**: This directory contains route definitions for your application. Routes map incoming requests to controller actions. `web.php` might contain routes for web pages, while `api.php` could define routes for your API endpoints.

6. **storage/**: This directory is used to store temporary or cache files generated by your application. It often contains logs, as seen in the `logs/` subdirectory.

7. **vendor/**: This directory typically contains third-party libraries and dependencies, especially if you're using Composer for dependency management.

Overall, it's a structured setup for a PHP web application, adhering to common conventions.
