Other features include routing, caching, authentication, database migration, ORM (Eloquent), Blade templating engine, queue management, and artisan command-line interface. Laravel's new features enhance web application performance, security, and functionality.

Q3. Explain the MVC pattern in Laravel.
Answer

This is another important question in Laravel interview questions for 5 years of experience. Laravel uses the Model-View-Controller (MVC) pattern, a core architectural pattern. Within Laravel, the MVC pattern is crucial in organizing code and separating distinct aspects of application logic. This separation enhances manageability and maintainability.

  • Model: The Model component represents the data and encompasses its business logic.
  • View: The View component presents the user interface that enables interaction with the data.
  • Controller: The Controller component handles user requests, interacts with the Model to perform required actions or retrieve data, and ultimately renders the appropriate View to visualize and interact with.

By applying the MVC pattern, Laravel ensures a clear distinction between these three components, promoting a more structured and scalable development approach.

Q4. What are available databases supported by Laravel 10?
Answer

Laravel 10 supports a variety of databases, allowing developers to choose the one that best suits their project requirements. The databases supported by Laravel 10 include MySQL, PostgreSQL, MariaDB 10.3+ (Version Policy), SQLite and SQL Server.

Laravel's database layer is designed to utilize the PDO (PHP Data Objects) library, allowing it to seamlessly integrate with a wide range of databases supported by PDO. This flexibility enables developers to connect Laravel with other databases, such as Oracle, IBM DB2, etc., by configuring the database connection settings accordingly.

Q5. How to make a constant and use globally?
Answer

You can create a constants.php page in the config folder if does not exist. Now you can put a constant variable with value here and can use it with

Config::get('constants.VaribleName');

Example

return [
   'ADMINEMAIL' => '[email protected]',
];
Now we can display with
Config::get('constants.ADMINEMAIL');

Q6. How to enable query log in laravel?
Answer

Our first step should be

DB::connection()->enableQueryLog();

After our query, it should be placed

$querieslog = DB::getQueryLog();

After that, it should be placed

dd($querieslog)

Example

DB::connection()->enableQueryLog();
$result = Blog:where(['status' => 1])->get();
$log = DB::getQueryLog();
dd($log);

Q7. What is reverse Routing in Laravel?
Answer

Reverse routing in the laravel means the process that is used to generate the URLs which are based on the names or symbols. URLs are being generated based on their route declarations.

With the use of reverse routing, the application becomes more flexible and provides a better interface to the developer for writing cleaner codes in the View.

{{ HTML::link_to_action('blog@list') }}

Q8. What is Middleware in Laravel?
Answer

Middleware in laravel works as a platform among the request and the response. It provides the mechanism for investigating the HTTP requests which are entering into your application. For instance, middleware in laravel ensures that the user of your particular application is authenticated. If they found that the user is not authenticated, it will redirect the user to the main login page of the application.

Example: If a user is not authenticated and it is trying to access the dashboard then, the middleware will redirect that user to the login page.

Q9. What is an artisan?
Answer
Artisan is a command-line interface (CLI) that provides developers with powerful and useful commands to help in Laravel application development. Artisan enables developers to enhance their productivity by automating routine operations, simplifying code generation, and facilitating efficient database management. This tool simplifies the process of building, maintaining, and managing Laravel applications.
Q10. What is the difference between {{ $username }} and {!! $username !!} in Laravel?
Answer

In Laravel, {{ $username }} and {!! $username !!} displays dynamic content within a Blade template. However, they have different behaviors depending on the context in which they are used.

{{ $username }} is used to display escaped output. This means that any special characters in the variable's value, such as HTML tags or JavaScript code, will be converted to their corresponding HTML entities to prevent them from being interpreted as code. This is done to help prevent cross-site scripting (XSS) attacks, where malicious code is injected into a web page.

{!! $username !!} is used to display unescaped output. This means the variable's value will be displayed exactly as it is, without any special characters being converted to HTML entities. This is useful when displaying HTML markup or other special characters.

However, using unescaped output can be risky, especially if the variable's value comes from user input. It can make your application vulnerable to XSS attacks. Therefore, you should always sanitize user input before displaying it on a web page and use the escaped output ({{ $variable }}) by default unless you have a good reason to use the unescaped output ({!! $variable !!}).

Conclusion

This is highly recommended you go through all these laravel interview questions twice or thrice before going to an interview. Also, try to give an example of every question wherever possible. This will add a bonus point to your plate and shows your expertise in laravel coding. Also, make sure your answers should not be lengthy or sounds like a boring story. Keep your answers short and clear with the help of examples.
