14 min.

Laravel is the most popular PHP framework at the moment, and it has been so for the past few years. All the Laravel benefits are one of the reasons for it, no doubt. Little wonder its developers are in high demand. However, that does not mean that every developer you encounter is the right person for your job. In fact, if you want to hire Laravel developers the interview stage is more than necessary. The Laravel interview questions and answers in this article would help you determine the expertise of the developer, their fit for the job, as well as their weaknesses.

What Do You Need to Know Before Hiring a Laravel Developer?

Two people might write different codes that perform the exact same function. Yet, the best one of both of them would be the one whose code is best optimized. However, it is not just the code that matters. Other important factors to consider include experience, as well as how the person fits into your organization’s culture. This section contains certain factors you must consider and answers to expect as you prepare your Laravel interview questions.

PHP knowledge

Laravel is a framework for PHP and so during questioning, developer applicants must demonstrate a good understanding of PHP is important to ensuring productivity and attaining expertise in it. You can only uncover this through the right PHP Laravel developer interview questions.

Even though this framework uses the same MVC architecture as Ruby on Rails and React JS, functions are still written and executed in PHP. More so, Laravel is not the same as CMS’s such as Drupal, Joomla or WordPress, all of which do not require any knowledge of a programming language. In essence, Laravel is PHP and PHP is Laravel. Therefore, as you quiz a developer on their handling of the Laravel framework, ensure that their answers demonstrate an efficient understanding of PHP as well.

Updated Knowledge

You can always identify a dedicated developer through Laravel job interview questions about how updated their knowledge of the framework is. No matter the level of the developer’s expertise, during the interview stage ask them questions concerning the latest developments in the Laravel world.

The extent of their knowledge reveals if the application is a priority for them. Up-to-date knowledge is very important because of how frequently it updates. What a programmer knows today about a particular function may become obsolete tomorrow. PHP Laravel framework interview questions should focus on updated knowledge in both the PHP language and the Laravel framework.

Portfolio and Experience

Beyond certifications and interviews, what really proves that a developer (or any programmer at all) is as good as they claim is their portfolio of past projects. Though this information would normally be on the resume. The discussion should still feature in your laravel job interview questions. In fact, industry experience is an important factor when examining a PHP Laravel framework developer’s portfolio before asking questions at the proper job interview.

Though, there are two ways to do this. Niche developers are scarcer but if you find one that matches your field, they usually have a more in-depth understanding of the industry than multi-niche programmers. Multi-niche developers rather bring flexibility and some useful extra perspective. In the end, the programmers you hire would be those that fit your needs best, but you must also ask the right Laravel job interview questions.

Work Record

Laravel interview questions and answers often focus on technical expertise. However, this is different. Here, the focus is on the soft skills of the programmer. For one, no developer works in isolation, even on development-only activities. You want to hire someone who is a team player and is apt to learn from others. You may also reach out to the developer’s previous employers and references to learn about their work practices. If you are outstaffing a project, reaching out to the previous clients of the company achieves the same purpose.

As against hiring programmers one after the other in order to put a team together, you may also consider the route of staff augmentation through outstaffing. The best developers may not be readily available in your location, not to mention the costs of hiring and onboarding new employees. Instead, a startup may optimize Laravel cost by hiring a development company. Augmenting your development workforce with outstaffed workers gives you access to cost-effective, flexible, and on-demand labor as well as equipment to make your project succeed.

The official website describes it as ‘the PHP framework for web artisans’. It uses the model-view-controller (MVC) architecture, just like similar frameworks like Symfony and CodeIgniter.

A quote of Taylor Otwell

This framework prides itself on its elegant syntax, which together with impressive functionalities built-in, make backend web development much easier. Some features provided include testability, configuration management, eloquent object-relational-mapping, etc. The philosophy is to “make the development process a pleasing one for the developer without sacrificing application functionality.”

It is likewise used to install features and requirements relating to frameworks on a per-project basis. The idea behind Composer is similar to Node.js Package Manager and Ruby’s Bundler. In essence, Laravel requires Composer to function properly. To use Composer to install Laravel, a developer employs the create-project command.

Therefore, ask questions that may throw them off balance without proving overwhelming considering their level of experience. PHP Laravel framework developer interview questions for intermediates should have the right blend of the theoretical and the practical.

What are the cons of Laravel?

How this question is answered during an interview is important because a developer has to recognize and acknowledge the limitations of the system they are using. This helps them to innovate ways to get around potential challenges. There are many reasons to choose Laravel; there are some cons to the framework as well, highlighted below:

  • Update Difficulties: Laravel itself admits that major updates may contain breaking changes. Though the official documentation says minor updates never contain breaking changes, some users have reported experiencing such time after time. Nevertheless, the framework provides support for this, explaining possible breaking changes for each (major) update and their risks of impacts on its website.
  • Difficult to Master: indeed, it is easy to learn. It teaches developers to adopt some of the most modern web development practices. However, the road to expertise is hardly straightforward. It requires a lot of experimentation to even grasp some of the underlying concepts. The solution to this is simply for the developer to keep practicing.
  • Application Migration: there is no doubt that Laravel has dethroned its predecessors such as Zend, CodeIgniter, and Symfony to become the foremost PHP framework. However, its undoing is that it does not allow for the smooth migration of applications based on these legacy frameworks to Laravel.

What are events and listeners?

On a basic level, events alert you to actions that take place in your application while listeners ‘listen’ to instances of events that occur. Both terms go hand-in-hand because a listener must be connected to a particular event in order to receive instances of that event.

What are packages in Laravel in detail?

Packages are for adding extra features to the application code. Some of the packages are framework-independent. Other packages are purpose-built for specific frameworks. Some popular Laravel-specific packages and their functions are highlighted below:

  • Spatie: for managing user permissions and roles in a database
  • Laravel Debugbar: to integrate PHP DebugBar with Laravel and adds a developer toolbar to an application
  • Entrust: allows you to use role-based permissions
  • Socialite: an official package. It is used to authenticate requests with OAuth providers
  • Laravel Mix: provides an interactive API for defining webpack build steps for your project
  • NoCaptcha: used to implement Google Recaptcha validation
  • Orchid: used to develop functions paramount to a business app
  • Bagisto: for building an eCommerce app

How does middleware work in Laravel?

Middleware is the link between a request and a response that provides the medium for the inspection and authentication of an application’s HTTP requests. Its functions also include logging requests, redirecting users, etc.

Scheme of how middleware in Laravel works

A user creates new middleware using the make:middleware Artisan command. Following this, you assign the middleware to a route and customize it based on your needs as well as the unique demands of the said application.

What is database migration, and how can you use it in Laravel?

Migrations are used to handle version control. Version control mainly involves managing changes to the application and its database structure. Migrations help team members collaborate on projects better, which means without friction. The Artisan command make:migration is used to generate a new database migration.

Migrations accumulate over the period of development, so much so that the database migrations directory may become bloated. When that happens, the best step to take is to use the schema:dump command to squash the migrations into one SQL file. There are two main migration functions: up and down. ‘Up’ is for adding new elements while ‘Down’ is for undoing previous operations.

What is CSRF protection, and when do you need it?

CSRF (fully known as Cross-Site Request Forgery) is a malicious exploit of an application through unauthorized activities. Web applications are particularly prone to CSRF attacks. However, Laravel has built-in protection against CSRFs. It works by generating “CSRF ‘token’ for each active user session managed by the application” automatically. These tokens are used for verification and authentication purposes. A new token is created for every new session; therefore, it is impossible for a malicious application to exploit it.

PHP Laravel Framework Interview Questions for Expert Developers (More than 4 Years of Experience)

How does Laravel’s command scheduler work?

Laravel’s Cron Job is an inbuilt tasks manager that makes it easier to automate operations. Now, you no longer have to write a new cron configuration entry for each task to be scheduled on the server. You can define scheduled tasks by:

A calendar and a clock
  • Creating a new artisan command
  • Using the callback method
  • Using the exec method for shell commands
  • Scheduling frequency options

How does testing work in Laravel applications?

Testing is unavoidable in software development. Therefore, PHP Laravel interview questions that do not include quizzes regarding testing are a no-no. Certainly not if the developer in question is an expert; after all, it’s the experts that lead the charge in testing.

PHPUnit is one of the commonest testing frameworks for PHP and it is supported by default in Laravel. There has been a greater focus on testing since version 5.2. To create a new test case, a user utilizes the Artisan command, make:test. Once the test begins running, the environment is automatically configured.

Each application contains two test directories: feature and unit. The latter is for testing small portions of code while the former is for testing the larger portions. Laravel recommends conducting more feature tests than unit tests. That’s because these types of tests provide the most confidence that your system as a whole is functioning as intended.

What does Eloquent ORM do in Laravel and what types of relationships are supported?

Eloquent is the name of the default object-relational mapper (ORM) used in Laravel. It provides a more convenient means to interact with a database. Hence, a developer does not need to write a length query. Eloquent ORM works with an ActiveRecord implementation so that developers can manage multiple databases.

Morpheus is talking about Eloquent

In ActiveRecord implementation, every model that is created via the MVC (model-view-controller) architectural pattern corresponds to a database table. The types of relationships supported in Eloquent ORM include:

  • One To One
  • One To Many
  • Many To Many
  • Has One Through
  • Has Many Through
  • One To One (Polymorphic)
  • One To Many (Polymorphic)
  • Many To Many (Polymorphic)

What is the database query builder?

Laravel’s database query builder is used to smoothly run database queries. Although, it can also be used to perform other database operations, including CRUD (Create, Read, Update, Delete) functions. Since SQL Injection attacks are a common threat, it uses the PDO parameter binding to protect your application from.

What is an IoC container? How does it work?

The IoC container (fully known as the inversion of control container, or simply the service container) is a tool used for handling class dependencies, automatically resolving dependencies, and easily achieving dependency injection. It resolves dependencies either by Closure callbacks or by automatic resolution. The IoC container is powerful, sophisticated enough to automatically resolve classes in most scenarios without configuration.
