How to get a session at Laravel

Learn how to create and use sessions in Laravel with this step-by-step guide and example.

Creating a Laravel Session

Laravel sessions allow you to store and retrieve data from the user's browser. It is an essential part of most web applications, as it allows you to authenticate users, save user preferences, and store other important information. In this tutorial, we'll walk through how to create and use a Laravel session.

Step 1: Install the Laravel Session Package

The first step is to install the Laravel session package. To do this, open your terminal and run the following command:

composer require laravel/session

This will install the laravel/session package into your application. Once it is installed, you will need to add the package to your application's service providers array in the config/app.php file:

'providers' => [
    // Other Service Providers
    LaravelSessionSessionServiceProvider::class,
],

The package is now installed and ready to be used.

Step 2: Create the Session Table

The next step is to create the session table. This table will be used to store the session data. To create the table, run the following command:

php artisan session:table

This will create a sessions table in your database. Now, when a user logs in, the session data will be saved to this table.

Step 3: Setting the Session Driver

The next step is to set the session driver. The session driver is responsible for storing and retrieving the session data. By default, Laravel uses the file driver, which stores the session data in the storage/framework/sessions directory. You can change the driver by editing the config/session.php file:

'driver' => env('SESSION_DRIVER', 'file'),

You can set the driver to 'database' to store the session data in the database, or to 'memcached' or 'redis' to store the session data in a memory cache.

Step 4: Creating the Session

Now that the session package is installed and configured, you can create a session. To do this, you will need to use the session() helper function. For example, to set a session variable called 'username' to 'john', you would use the following code:

session(['username' => 'john']);

You can also retrieve a session variable by passing the variable name to the session() helper function. For example, to retrieve the 'username' variable, you would use the following code:

$username = session('username');

Now that you know how to create and use a Laravel session, you can use it to store and retrieve user data in your application.
