Laravel Interview Questions for BEGINNERs:

1. What is Laravel?

Laravel is a free, open-source PHP web application framework created by Taylor Otwell and intended for the development of web applications following the model–view–controller (MVC) architectural pattern. It was released in June 2011 with an emphasis on programmer productivity and “the sweet spot” between developer flexibility and simplicity while also improving the speed of development.

2. What features does Laravel offer?

Laravel’s features include:

– Model View Controller (MVC) architecture

– Eloquent ORM (Object Relational Mapping)

– Artisan CLI (Command Line Interface) tool for automation and management of your application.

– Laravel Mix for managing CSS, JavaScript, Less, SASS, and much more.

– Blade Templating Engine

3. What makes Laravel so popular?

The first thing that makes Laravel so popular is its community. There are thousands of people who support each other and help each other out when it comes to using the framework. The second reason why Laravel is so popular is that it’s simple and easy to use. The third reason why Laravel is so popular is that it has a large collection of packages (called “libraries”) that can be added on top of the core framework in order to add new features and functionality to your application.

4. What is the Laravel ecosystem?

The Laravel ecosystem comprises all the tools and services that surround the Laravel framework. These include Laravel Cashier, which allows you to accept payments through Stripe or PayPal; Homestead, a preconfigured Vagrant box that makes it easy to get started with Laravel on any platform; Forge, which lets you create your own boilerplates and packages for use in your projects.

5. What is your favorite feature of Laravel?

My favorite feature of Laravel is that it is simple yet powerful. It’s easy to learn and use, but it also has a lot of features that can be used for complex applications.

6. Why do you like Laravel?

I like Laravel because it allows me to build applications with minimal effort quickly. It has a strong community behind it and has been constantly supported by the creator of the framework himself. I also love the fact that it is object-oriented, which makes it easy for me to understand how things work in an application built on the Laravel framework.

7. What is the difference between the service provider and facade provider in Laravel?

A service provider is a class that provides Laravel with information about a certain type of service. It’s used to define the methods, along with their arguments and return types, that should be used when interacting with a specific piece of functionality.

Facades are classes that provide an easy way to interact with complex systems such as databases or mail servers. They wrap up many lines of code into simple functions that can be called easily.

8. What are the main components of Laravel?

Laravel has two major components: a collection of core libraries and a set of tools that make it easy to build web applications using those libraries. The core library contains classes that help you work with the request, response, and view objects, while the toolset provides functionality for things like authentication and authorization.

In addition to these two components, there are several other optional features of Laravel that can be added on top of your application if needed. These include support for events that are handled by event listeners in order to provide functionality such as logging or redirecting users after successfully logging in; functional testing support through integration with PHPUnit; integrated package management through Composer; and more!

9. What are the benefits of using Laravel over other frameworks?

Laravel has excellent documentation, which helps you to get started with it. It also has a large and active community of developers who contribute to its growth in many ways, such as writing tutorials, writing code snippets, and so on. This helps beginners learn new things quickly and also helps them improve their skills. Documentation is available in multiple languages and can be accessed easily from anywhere. Plus, Laravel has an active support forum where you can find answers to almost all your queries related to this framework.

10. What is Laravel’s license?

The Laravel framework is licensed under the MIT license and can be used freely.

11. What do you think about the future of Laravel?

I think it will be around for a while because it’s got such a strong community backing it up, and lots of companies are choosing to use it as their go-to framework. Plus, they’re always adding new features that keep people coming back!

12. What is Lumen?

Lumen is a micro-framework built on top of Laravel that’s designed to help you build simple APIs. It’s perfect for building small applications or prototypes that don’t need all the extra bells and whistles that come with Laravel.

13. What are some of the benefits of using a micro-framework like a Lumen instead of a full-stack framework like Laravel?

Micro-frameworks tend to be much faster than full-stack frameworks because they’re built on top of other frameworks instead of having their own libraries. They also have less overhead, which means they’re easier to deploy and maintain than full-stack frameworks.

14. Where can you find the documentation for a library or package in Composer?

You can find the documentation for a library or package in Composer by looking at its README file. The README file is located at the root of the directory.

Laravel Interview Questions for INTERMEDIATE:

1. How long have you been using Laravel?

I’ve been using Laravel for about eight years now – I started learning about it when I was working as an intern at an agency, and I fell in love with it immediately! Since then, I’ve built tons of apps with this framework – both personal projects and client work alike – so I feel like I have a pretty solid understanding of what makes it great (and what doesn’t).

2. What are the different ways of implementing authentication in Laravel?

Laravel is a PHP web framework that makes it easy to build simple or complex applications. It is a perfect choice for developers who are looking for an alternative to the traditional PHP framework.

Laravel has an authentication system that supports multiple ways of implementing authentication in Laravel.

The three most common ways of implementing authentication in Laravel are:

1. Using Laravel Passport

2. Using Laravel Socialite

3. Using Laravel Collective Auth

3. What is MVC?

MVC (Model View Controller) architecture divides your application into three sections: model, view, and controller. The model contains all of your business logic, the view presents data to the user, and the controller mediates between model and view by translating data for display in a template.

4. What is Laravel Eloquent ORM?

Eloquent ORM provides a beautiful API over database queries in order to help developers with creating complex relationships between models without having any knowledge about SQL queries.

5. What is the difference between Laravel and other PHP Frameworks like Symfony or CodeIgniter?

Laravel has a lot of features that make it stand apart from other PHP frameworks like Symfony or CodeIgniter:

– It’s built with testability in mind so that developers can easily write tests for their code without having to worry about extending classes or writing boilerplate code.

– It comes with an extensive collection of built-in functionality like pagination, routing, and validation, which saves time for developers as they don’t have to write these things from scratch all the time.

6. What is a good way to handle an application that requires multiple database connections?

The best way to handle this is by creating your own configuration file. In this file, you can specify all of the different databases and their corresponding connection strings. This makes it easy for you to change the database connection string in one place instead of having to modify every single place where your application connects to the database.

7. How do you find out if Laravel is right for business?

First of all, let’s clarify what we mean by “right”: the framework should fit your team’s skill set, the features you need to build, and (to some extent) your budget. If you don’t have any specific requirements that dictate what kind of a framework you need at this point in time – or if there are none at all – then Laravel may be perfect for you!

8. What is Laravel Migration?

Migration is the process of transforming your database from one version to another. If you change data types or add indexes or other features (e.g., column names), then you will need to run migrations to update your database’s structure accordingly.

9. How to add a new route to the Laravel application?

There are two ways to add routes to Laravel applications: with or without controllers. If you want to add a route without a controller, use the Route::get() method in your app/Http/routes.php file like this: Route::get(‘foo,’ function () { return ‘Foo!’;}); This will create a GET route called foo that returns “Foo!”.

If you want to add a route with a controller action, use the Route::controller() method instead like this: Route::controller(‘foo’, function () { return ‘Foo!’;}); This will create a GET route called foo that returns “Foo!”.

10. How to deal with a large number of API calls?

If you have a large number of API calls in your application, Laravel can help you out. It has an API Rate Limiting feature that helps you manage the number of API calls made to your application. The rate limit is set in the .env file, and it can be changed according to the needs of your application.

11. What is a service provider?

A service provider is a class that allows you to attach behaviors to the Laravel framework. These behaviors can be anything from logging and error handling to more complex tasks like route registration and middleware. Service providers are located in the app/Providers directory and must be named after the package they represent. For example, if you wanted to provide a custom mailer system for your application, you could create an App\Providers\MailServiceProvider class.

12. How can you use Laravel to develop web applications?

You can use Laravel to develop web applications in the following ways:

– You can create custom controllers that are responsible for handling user requests and returning responses.

– You can use views to render HTML templates that display data from your application’s models or present other content to the user.

– You can connect your application with existing data sources using Eloquent, which is an ORM (Object Relational Mapper) library written in PHP 5.3+.

13. What is Laravel logging?

Laravel logging allows you to collect information about your application’s performance and store it in log files so you can analyze it later on if necessary. This includes things such as database queries, exceptions thrown by controllers or models, cache hits/misses, redirects performed by your application’s routes – everything! There are a number of different ways you can configure how much information gets logged (or not logged)

14. What is a pivot table? How can it be used to query data in your database?

A pivot table is a database query tool that can be used to display large amounts of data in an organized format. It is most often used to convert data from one database table into another and is particularly useful when you want to compare information from a number of tables at the same time.

Pivot tables are easy to use, but they do require some planning ahead of time so that you can ensure your database is set up correctly.

15. Explain the difference between “abstract” and “concrete” classes in PHP.

In PHP, an abstract class is a class that cannot be instantiated. It’s used to define the methods and properties of a class without needing to define the application logic. For example, you could create an abstract class called “Car” that has methods like “drive()” and “stop().” You wouldn’t need to define any specific functionality for these methods because you would only use them as a template for child classes to inherit from.

Concrete classes are classes that can actually be instantiated. They usually contain some kind of functionality, but they may also inherit from another class or implement interfaces.

Laravel Interview Questions for Experts:

1. Can you explain the relationship between models and routes?

Routes are used to map HTTP requests to controllers, which then map them to specific actions. The routes can be specified inside the routes/web.php file in your project directory. The controller file contains instructions on how to handle each request, whereas models are used for storing data retrieved from a database or API call into variables that can be used throughout your application’s codebase.”

2. How does Laravel handle routing?

Routing is used by Laravel

applications to map URLs with actions or events that occur within those pages. Routing can be done manually within each controller or automatically by configuring routes in your application’s configuration file (app/config/routes.php). Routes are defined by specifying which controller should be called when a given request comes in from a specific URL pattern (e.g., /search).

3. What is the difference between Laravel’s “view” and “controller” systems? 

The “view” and “controller” systems in Laravel are both responsible for generating HTML that is delivered to the user. The view system is responsible for reading data from models, generating HTML, and returning it to the browser. The controller system is responsible for handling requests from users, reading data from models, and sending information back to the browser. The control system also handles flash messages and redirects.

4. What is the difference between Eloquent and ActiveRecord?

Eloquent is a Laravel ORM (Object-Relational Mapper) that provides an expressive, beautiful, and simple ActiveRecord implementation for working with relational databases. It’s accessible, easy to use and extend, and makes use of well-established techniques from the active record pattern.

ActiveRecord is a framework in the Ruby on Rails web application framework that provides a domain model for representing data in a database.

5. How can you use SQLite in Laravel?

SQLite is a powerful, lightweight, and easy-to-use database that has been used in many projects. Laravel makes it easy to use SQLite in your application with the built-in Eloquent ORM.

You can create an instance of the SQLite database using the connection() function. This function accepts a string that defines the location of your database. You can also pass an array to define multiple configurations for your application’s database connection:

$database = DB::connection(‘sqlite::memory:’);

6. What is the Blade Template Engine in Laravel?

The blade is a simple yet powerful templating engine provided with Laravel. It allows you to write razor-sharp HTML code, and it’s completely integrated with the rest of the framework.

The blade is not just an HTML template system: it’s a powerful tool for writing any kind of text-based code, including PHP, JavaScript, and CSS.

7. What’s the .env file in Laravel?

The .env file is a file that stores your application’s configuration parameters. It is used to store sensitive information such as database passwords and API keys.

The .env.example file is a template for the .env file and is usually created automatically by Laravel when you install it. The purpose of this file is to show you what goes where in a normal, acceptable way so people can see what they can expect when they open up the .env file themselves.

8. How should you configure environment variables for your Laravel project?

Laravel provides a variety of ways to configure your projects. One way is through environment variables, which are useful because they allow you to set up different configurations for different environments (such as production and development).

To configure your environment variables in Laravel, open up your .env file (located in the root directory of your project) and add a new key-value pair. For example:


Then, run PHP artisan env: set DB_HOST=localhost in the terminal (or equivalent) to set this value.

9. How does object-oriented programming differ from procedural programming?

In object-oriented programming, you create objects that represent real-world things—like a car or an employee. Each object has its own set of properties and methods. Classes are the blueprint that describes how objects should be created.

With procedural programming, you write code in a linear order. The code is more rigid and doesn’t have much flexibility because it follows the order in which it’s written.

10. What is a PHPUnit test case, and how can you write one in Laravel?

A PHPUnit test case is a class that contains test methods. These tests are meant to test the functionality of your application, and they can be run individually or as part of a suite. You can write one in Laravel by using the PHPUnit facade, which provides access to all of the testing functionality. Here’s an example:


namespace App;

use Illuminate\Foundation\Testing\DatabaseMigrations; use Illuminate\Foundation\Testing\DatabaseTransactions; use Illuminate\Foundation\Testing\TestCase; use Illuminate\Foundation\Testing\WithFaker; use Illuminate\Foundation\Testing\WithoutFaker;

class ExampleTest extends TestCase { use DatabaseMigrations, DatabaseTransactions, WithFaker, WithoutFaker; /** @test */ public function should_create_user() { $this->post(‘/users’, [ ‘name’ => ‘John Doe’, ’email’ => ‘’, ]); $this->get(‘/users’); } }

11. How would you implement a simple CRUD application in Laravel?

I would implement a simple CRUD application in Laravel by creating an Eloquent Model, a Controller, and a View.

To create an Eloquent model, I’d write the following code:

<?php namespace App; use Illuminate\Database\Eloquent\Model; class User extends Model { protected $fillable = [ ’email’, ‘password’ ]; }

Then I’d create a controller so that it could handle requests from clients:

<?php namespace App; use Illuminate\Http\Request; use App\User; class UserController extends Controller { public function create(Request $request) { return User::create($request->all()); } }

Finally, I’d make sure that my view contains the code needed to display information about users when they’re created or updated.

12. Can you explain how to use Laravel’s built-in authorization system?

Laravel’s built-in authorization system is very easy to use. The first thing you want to do is create a User model, which will be the class that represents the users in your application. This can be done by running the following command:

php artisan make:model User

Next, you’ll want to create a migration for this model. You can do this by running the following command:

php artisan make:migration create_users_table

After this has been run, you’ll need to populate this new table with some data using Artisan’s migrations feature. You can do this by running the following command:

php artisan migrate

Once all of these commands have been run, you’ll find that you’ve created an authentication system that allows you to authenticate users with their email addresses and passwords.

13. What do you think of the following code snippet? Why or why not?

$foo = ‘bar’; $baz = get_class($foo); if ($baz === ‘Foo’) echo ‘Foo is true’; else echo ‘Foo is false’;

I would not use this code snippet because it is not performant. This code snippet will try to get the class of $foo, and if that class is Foo, it will print out “Foo is true”. If the class of $foo isn’t Foo, it will print out “Foo is false”.

This means that if you have a lot of classes in your project, and you call this code snippet for each of them, you’ll be doing a large amount of unnecessary work. If you need to know whether an object is an instance of Foo or Bar, you should use PHP’s instance of operator instead:

$foo = ‘bar’; $baz = get_class($foo); if ($baz === ‘Foo’) echo ‘Foo is true’; else echo ‘Foo is false’;

DevzClub Guide to Laravel Developer Interview

1. 3 Strategies to Help Prepare for a Laravel developer interview with CTO

1. Practice, practice, practice! Get your hands dirty and start building something. The best way to get better at something is to do it, and the best way to get better at coding is by coding.

2. Don’t be afraid to ask questions. If you don’t understand something, don’t be afraid to ask the interviewer. It’s their job to help you learn the skills they’re looking for in their ideal candidate, so don’t be shy about asking questions if you have them!

3. Show off what you’ve learned! Show off your skills by creating something awesome during the interview process—whether it’s a project that relates directly to what they’re hiring for or just something cool and creative that shows off how talented you are as a coder.

Bonus Tip:

Find a mentor:

In addition to these two strategies, there’s one more thing that can help make your interview much easier: finding a mentor who can guide you through the process of preparing for the interview and answering questions about your skill set when they come up during the interview process itself!

2. Five qualities silicon valley companies like Google and Netflix look for when interviewing Laravel developers.

In order to get hired as a Laravel developer, you need to be able to demonstrate these five qualities:

1. You’re a self-starter. The best Laravel developers don’t wait for others to give them tasks—they are always looking for ways to improve their skills and advance the project, even if that means taking on extra work or going the extra mile.

2. You’re comfortable with solving problems on your own. There’s no one-size-fits-all answer when it comes to coding solutions and meeting client needs—you’ll have to think outside of the box and come up with innovative solutions every day.

3. Understanding of databases: You’ll need to know how to use databases like MySQL or MongoDB if you want to pass the interview process for a job as a Laravel developer at one of these companies because they rely heavily on these technologies for their products and services (and for storing data).

4. You’re able to communicate clearly and effectively with other members of the team (and your clients). Your coworkers are your allies—don’t keep secrets or get angry at them for asking too many questions! They want what’s best for you and your work product just as much as you do!

5. You can work well under pressure. There’s never enough time in the day when working on projects like these—you’ll need to be able to stay calm in high-pressure situations so that you can focus on getting things done rather than freaking out about how much time has passed since

Four mistakes to avoid during Laravel Interview

1. Don’t be arrogant

Also known as “don’t try to prove how smart you are,” this mistake is more common than most people realize. You don’t want to come across as someone who thinks they know everything or who thinks they’re better than everyone else in the room—even if you do! The key here is to just be humble and let your work speak for itself.

2. Don’t lie about your experience

It’s tempting to pad your resume with a few extra years of experience or add some projects that never actually happened (you know what we mean). But if an interviewer asks about a particular project on your resume, don’t lie about it—the truth will come out eventually! Instead, focus on talking about your actual experience and accomplishments as an employee or freelancer in the field of web development/design or whatever field it is that interests them most.

3. Don’t get defensive

If you’re asked a question that is difficult or feels like it’s off-base, don’t take it personally. Your interviewer is just trying to get a sense of who you are and how well you’ll fit in with the rest of the team. It’s okay if they’re not asking questions that are relevant to what you’ve studied or done in the past; they might just want to see how well your communication skills transfer over into an interview setting.

4. Avoid giving short answers:

You should always give detailed answers to the questions asked by the interviewer. They will judge your knowledge base and communication skills according to your responses. So, try explaining each detail of the question thoroughly so that they can understand it better and make the right decision about your skill set.

5. How should I start preparing for the interview?

The first thing to do before you go for a Laravel developer interview is to find out about the company. You must know what the company does, who their clients are, and what kind of problems they solve. This will help you understand where your skills fit in with the company’s needs.

You can also ask some questions about the company, like how many developers they have and how long they’ve been around. These questions will give you an idea of how much responsibility you’d have at the company and whether or not they’re well-established in their field.

Once you’ve learned a little bit about the company and its goals, it’s time to focus on getting prepared for your interview!

6. How can I impress the interviewer?

1. Read up on the Laravel framework! This is the best way to impress your interviewer because it shows that you’ve done your research and are serious about wanting to work for them. It also shows that you know what you’re getting into.

2. Show an interest in learning new things but also a familiarity with the language/framework. If you’ve been using Laravel for years, don’t feel like you need to explain everything about it—but do make sure that your interviewer knows that you aren’t just applying because of its popularity or because it’s what everyone else uses (unless those things are true).

3. Show confidence in yourself and your skill set! You may have less experience than other candidates, but if they’ve made it far enough in the hiring process, then they must have seen something they liked in your application or resume—so own those skills and tell them how great they are!

7. What are three tips that can help me to pass the Laravel Interview?

1. Think of your answers as a story.

When you talk about your experience with Laravel, don’t just throw out facts like you’re reading a list of ingredients. Instead, think about how those facts fit together to create a story about how you use the framework in your work and what that means for your potential employer.

2. Use examples from real-world projects to help tell the story.

It’s not enough to say that you use Laravel; if an interviewer asks for an example, it’s helpful if you can give them one! That way, they can see how well you’ve incorporated Laravel into the workflow of your project—it’s more than just knowing how the framework works on its own.

3. Don’t be afraid to ask questions! 

If you’re working on a project that is particularly complicated, or if there’s something you don’t understand, ask your interviewer for help. They’re there to help you succeed—they’ll be happy to answer any questions you have.

8. How can I prove a valuable addition to the team in a Laravel interview?

To prove value addition, you can:

– Explain that you’re a fast learner who learns new technologies quickly.

– Demonstrate your ability to work with others by showing how you’ve collaborated on projects, even if they weren’t in Laravel.

– Describe how you’ve used the skills from previous jobs to contribute to the team’s success.

9. How to beat nervousness during a Laravel interview?

If you’re looking to beat nervousness during a Laravel interview, there are a few things you can do.

First, try to relax. If you’re feeling anxious and tense, it’s going to show in your body language and tone of voice. You want to appear confident, not anxious!

Next, make sure you know the answers to the questions that might be asked of you. It’s one thing to memorize them word-for-word; it’s another thing entirely when the interviewer asks you a question that requires more than just a recitation of facts. Answering with confidence will help put your nerves at ease.

Finally, remember that if your interviewer asks about something that isn’t on the job description or in any other documents they’ve given you (like an applicant guide), they might just be trying to throw you off balance! So don’t panic—just smile and say, “I’m glad we could get that cleared up.”
