What Are Laravel Observers and How Do They Work in 2025?

In the rapidly evolving landscape of PHP frameworks, Laravel continues to shine as a robust and versatile tool for developers. In 2025, one aspect that remains a cornerstone of its architecture is Laravel Observers. This feature is integral for maintaining clean and manageable code, particularly in handling Eloquent events.

What Are Laravel Observers?

Laravel Observers are essentially callbacks or event listeners that allow you to listen for specific Eloquent events. These are events triggered during the lifecycle of a model within Laravel’s Eloquent ORM, such as creating, updating, deleting, etc. Observers allow developers to attach specific logic to these events, making them a powerful feature for managing side effects and ensuring code separation.

How Do Laravel Observers Work?

Observers work by defining a class with methods that correspond to various Eloquent model events. Once you define the observer class, you associate it with a particular Eloquent model. Here’s how the process typically unfolds:

1. Create an Observer Class: The first step is creating an observer class. This can be done using the Artisan command:

1

   php artisan make:observer UserObserver --model=User

This command creates an observer class specifically for the User model.

1. Define Event Methods: Within your observer class, you define methods for the events you want to handle. For example, if you want to execute logic after a user is created, you might define a method like so:

1
2
3
4

   public function created(User $user)
   {
       // Logic to execute after a user is created.
   }

1. Register the Observer: Finally, you need to register the observer, typically within the boot method of a service provider:

1
2
3
4
5
6
7

   use App\Models\User;
   use App\Observers\UserObserver;

   public function boot()
   {
       User::observe(UserObserver::class);
   }

By following these steps, you can effectively utilize observers to handle complex logic tied to your models, maintaining a clean and organized codebase.
