What is the .env file in Laravel, and how do I use it?

Its core functions include: 1. Centrally manage database connections, API keys and other configurations; 2. Call variables through env() or config() functions; 3. After modification, the configuration needs to be refreshed before it takes effect; 4. It should not be submitted to version control to prevent leakage; 5. Multiple .env files can be created for different environments. When using it, you should first define variables and then call them in conjunction with configuration file to avoid direct hard coding.

How do I use the @can Blade directive to check authorization permissions?
In Laravel, the @canBlade directive is used to check in the view whether the user has permission to perform a specific action. 1. The basic usage is @can('ability name', model), for example, when displaying the "Edit" button, use @can('edit-post',$post) to wrap the link; 2. You can combine the @else or @cannot instructions to handle alternative content when there is no permission; 3. If the policy method requires multiple parameters, it can be passed through an array, such as @can('update-comment',[$comment,$post]); 4. For global permissions that do not involve the model, you can directly use @can('manage-settings') to check. Should

What is a single action controller?
Single action controllers are suitable for handling a single HTTP request, especially when logic is complex but no full controller is required. It keeps the code concise by including only one __invoke method, which is commonly found in the Laravel or RubyonRails framework; usage scenarios include building endpoints for non-standard resource routing, API development and microservices; when created, it can be generated through command-line tools and written directly in __invoke; the key point is to keep it lightweight, focus on a single responsibility, and use it in combination with form requests or service classes to improve maintainability.

What are Eloquent relationships (one-to-one, one-to-many, many-to-many)?
The Eloquent relationship in Laravel is used to connect different database tables through a model to simplify associated data operations. One-to-one relationships such as user and information: the User model uses hasOne (Profile::class), and the Profile model uses belongsTo (User::class). One-to-many relationships such as articles and comments: The Post model uses hasMany(Comment::class), and the Comment model uses belongsTo(Post::class). Many-to-many relationships such as users and roles: both the User and Role models use belongsToMany() method, and the relationship is managed through intermediate tables.
