What is Laravel?

Laravel is considered by many to be the default framework for creating PHP-based websites and web applications at scale. It has become one of the most popular (if not the most popular) PHP web application frameworks due to its elegant and functional syntax, extensive features, and developer-friendly approach.

Laravel provides developers with a robust toolkit for building all sorts of web applications (from simple web pages to complex enterprise platforms) rapidly and efficiently. It aims to simplify the development process by offering an expressive syntax, modular architecture, and a wide range of built-in features.

Laravel’s powerful ecosystem makes it an ideal choice for developing both simple and complex web applications.

A Brief History of the Laravel PHP Framework

Taylor Otwell released Laravel in 2011 as a personal project. His goal was to improve on CodeIgniter — which, at the time, was a well known and widely used framework. He aimed to address some of the limitations he encountered in CodeIgniter and to incorporate modern PHP features and best practices.

After several iterations, Taylor open-sourced Laravel under the MIT License, making it freely available to the developer community. The Laravel framework quickly gained traction and garnered a dedicated following due to its syntax, features, and ease of use.

Laravel’s popularity continued to rise with each subsequent release. This open-source PHP framework adopted a regular release cycle, introducing new features, enhancements, and bug fixes to keep up with the evolving needs of the web development community as well as the several improvements the PHP language had during that period.

The Laravel community also played a significant role in the Laravel framework’s growth and success. A vibrant community of developers actively began to to contribute to Laravel’s development, documentation, and ecosystem. This collaborative effort has continued to solidify Laravel’s position as the leading open-source PHP framework to this day.

The Purpose of Laravel

Laravel’s primary purpose is to simplify the development process and make it more efficient and enjoyable for the developer. It achieves this by offering a very functional and well-designed syntax, along with a wide range of tools, and by encouraging PHP and web development best practices. Laravel’s philosophy revolves around the following key principles:

  • Expressive Syntax. Laravel aims to provide a simple, clean, and expressive syntax that allows developers to write code that’s both readable, maintainable, and efficient.
  • Modularity. The Laravel framework is designed with a modular architecture, allowing developers to use specific components independently or together to build applications of different complexities.
  • Developer Experience. Laravel prioritizes the developer’s experience by providing a friendly community, detailed documentation, and built-in tools that enhance productivity and ease of development.
  • Security. Laravel has a focus on security and includes features like CSRF protection, SQL injection prevention, and secure authentication and authorization mechanisms out of the box.
  • Extensibility. Developers can extend Laravel’s core functionality by creating custom packages and integrating third-party libraries.

Together with the common features we can find in most PHP frameworks — such as routing and templating — Laravel provides a deep array of other functionalities out of the box. Let’s have a look at some of the most important ones, and also see how they’re implemented in the Laravel framework.


Authentication is crucial for web applications, allowing users to access secure areas and perform actions based on their roles through authorization (more on that later). Writing an authentication system from scratch can be like re-inventing the wheel, and that’s why Laravel provides a very convenient way to implement user authentication out of the box:

// Example of user registration
use App\Models\User;

public function register(Request $request)
    $validatedData = $request->validate([
        'name' => 'required|string|max:255',
        'email' => 'required|string|email|unique:users|max:255',
        'password' => 'required|string|min:8|confirmed',

    $user = User::create([
        'name' => $validatedData['name'],
        'email' => $validatedData['email'],
        'password' => Hash::make($validatedData['password']),

    // Additional logic, such as sending a welcome email, can be included here.

    return redirect('/home');

In this example, we’ve shown a simplified version of a user registration controller method. Laravel’s built-in validation and hashing mechanisms make it easy to handle user registration securely without the need to re-write all that code and expose a web app to possible security vulnerabilities.


Authorization is the process of determining what actions a user is allowed to perform within the application. Laravel’s authorization features work hand in hand with authentication and provide a straightforward way to define and manage user permissions:

// Example of authorizing a user action
if ($request->user()->can('update', $post)) {
    // The user is authorized to update the post

In this example, we’re using Laravel’s authorization functionality to check if the authenticated user can update a specific post. Laravel’s policies and gates allow web developers to encapsulate authorization logic within dedicated classes, enhancing code organization and maintainability.

Eloquent ORM

An ORM is a vital component of modern PHP frameworks.

ORM stands for object-relational mapping. It’s a programming technique that allows developers to interact with a relational database using object-oriented programming (OOP) concepts and principles. ORM serves as a bridge between the application’s object-oriented code and the relational database, enabling web developers to work with data more naturally and intuitively without the need to worry about which database engine is running in the background.

Eloquent is Laravel’s implementation of the active record pattern (software design pattern used in object-oriented programming to represent data stored in a relational database as objects), which simplifies database interaction and management by using a more expressive syntax:

// Example of using Eloquent to retrieve data
use App\Models\Post;

$latestPosts = Post::orderBy('created_at', 'desc')->take(5)->get();

// Example of saving data
$post = new Post;
$post->title = 'New Post';
$post->content = 'This is a new post created with Eloquent.';

Eloquent allows web developers to interact with the database using PHP classes and provides various methods for performing common database operations like querying, inserting, updating, and deleting records.

Database Migrations

Database migrations enable developers to version control the database schema and easily share changes with other team members:

// Example of creating a migration
php artisan make:migration create_posts_table

// Example of a migration file
public function up()
    Schema::create('posts', function (Blueprint $table) {


Never trust data inserted by the user! Validations are essential for ensuring that data submitted by users meets specific criteria before it’s processed or stored:

// Example of validating a form request
use Illuminate\Http\Request;

public function store(Request $request)
    $validatedData = $request->validate([
        'name' => 'required|string|max:255',
        'email' => 'required|string|email|max:255|unique:users',
        'password' => 'required|string|min:8|confirmed',

    // Logic to store the user data

Laravel provides a convenient way to validate incoming data using form requests or direct validation methods, reducing the boilerplate code needed for data validation. Laravel has over 90 powerful, built-in validation rules!

Notifications and Email

Laravel’s notification system enables us to send notifications to users via various channels, including email:

// Example of sending an email notification
use App\Notifications\InvoicePaid;
use Illuminate\Support\Facades\Notification;

$invoice = ...; // Fetch the invoice instance
$user = ...; // Fetch the user instance

Notification::send($user, new InvoicePaid($invoice));

With notifications, we can easily notify users about events such as password reset requests, order confirmations, or any other custom notifications our web app requires.

File Storage

Laravel provides a simple and consistent API for working with file systems, supporting local storage, Amazon S3, and other cloud storage services:

// Example of storing an uploaded file
use Illuminate\Support\Facades\Storage;

$path = $request->file('avatar')->store('avatars');

// Example of retrieving a file
$url = Storage::url('avatars/file.jpg');

This feature allows developers to straightforwardly manage file uploads, downloads, and storage, abstracting away the complexities of dealing with different storage options.

Job Queues

Job queues allow us to defer time-consuming tasks — such as sending emails or processing data — to be executed asynchronously:

// Example of dispatching a job to the queue
use App\Jobs\SendWelcomeEmail;
use Illuminate\Support\Facades\Queue;

Queue::push(new SendWelcomeEmail($user));

By using job queues, we can improve the performance and responsiveness of our application, as time-consuming tasks are offloaded to a separate queue that can be processed later by a worker process.

Task Scheduling

Laravel’s task scheduling feature enables us to automate the execution of certain tasks at specific intervals:

// Example of scheduling a task
use Illuminate\Console\Scheduling\Schedule;

protected function schedule(Schedule $schedule)
    $schedule->job(new SendDailyReport)->dailyAt('23:55');

In this example, we schedule the inspire Artisan command to run hourly and a custom job (SendDailyReport) to be executed every day at 23:55. This feature is particularly useful for performing periodic tasks, like sending daily emails or clearing temporary data. By using Laravel task scheduling, we effectively eliminate the need for relying on lower-level mechanisms like cron jobs.


Laravel comes with a comprehensive testing suite, allowing developers to write unit tests, feature tests, and integration tests effectively:

// Example of a feature test
use Tests\TestCase;
use App\Models\User;

public function test_authenticated_user_can_access_dashboard()
    $user = User::factory()->create();

    $response = $this->actingAs($user)->get('/dashboard');


Laravel’s testing tools facilitate writing tests that ensure our web application behaves as expected, catching bugs and regressions early in the development process.

Laravel Packages

Overt time, Laravel has become renowned for its packages. Laravel made it easy for the developer to implement things like authentication, billing, CRM features, and more. Some of the best packages ended up being official Laravel releases and are now an integral part of the Laravel ecosystem. The best known of them are Laravel Spark and Laravel Breeze.

Laravel Breeze

Laravel Breeze is a starter kit for building Laravel applications with basic authentication. It provides a simple and customizable way to set up user registration, login, password reset, and email verification features.

Breeze is a great tool for projects that require basic authentication without the need for complex features. It uses Laravel’s Blade templating engine for views and Tailwind CSS for styling, making it easy to customize the appearance of our apps.

Laravel Spark

Laravel Spark is a more comprehensive solution that extends beyond basic authentication. It’s designed for rapidly launching subscription-based SaaS applications.

Spark offers features like team management, subscription billing, user roles, and more. It comes with a Vue.js frontend and integrates with Stripe for payment processing.

Laravel Spark significantly speeds up the development of subscription-based web applications by providing pre-built functionality and UI components.

Both Laravel Breeze and Laravel Spark are designed to enhance developer productivity and simplify the process of building common web application features. They streamline the process of building and launching web applications with Laravel.
