Learn how to delete cookies in Laravel

Laravel is a popular PHP framework for building web applications quickly. Cookies are a commonly used data storage method in web applications. In Laravel, you can easily create and use cookies. However, sometimes you need to delete cookies from your application. In this article, we will introduce ways to delete cookies in Laravel.

1. Introduction

First, let us briefly understand what cookies are. A cookie is a small piece of text information sent by the server to the client browser through the HTTP protocol. The browser stores the cookie on the client and sends the cookie back to the server the next time it visits the same server. Cookies are usually used to store user authentication information, user preferences and other data.

Creating cookies in Laravel is very easy. You can create a new cookie using the Cookie class provided by the framework.

2. Create a cookie

In order to create a new cookie, you can use the following code:

use Illuminate\Support\Facades\Cookie;

$response = new Response('Hello World');

$response->withCookie(Cookie::make('name', 'value'));

In the above code, we use the withCookie method to add to the response a cookie. The Cookie::make() method is used to create a new cookie object. This method accepts two parameters:

1. The name of the cookie.
2. The value of cookie.

After creating the cookie, you can access the value stored in the cookie by:

use Illuminate\Support\Facades\Cookie;

$name = Cookie::get('name');

echo $name; // output: value

In the above code, we used the Cookie::get() method to obtain The value stored in the cookie.

3. Delete cookies

You can delete cookies from your Laravel application through the forget() method provided by the Cookie class. You just need to call the method and specify the name of the cookie you want to delete.

The following is an example of deleting cookies:

use Illuminate\Support\Facades\Cookie;

$response = new Response('Hello World');

$response->withCookie(Cookie::forget('name'));

In the above code, we used the withCookie() method and Cookie::forget() method to delete the name "name" from the response cookies. When calling the withCookie() method, we pass the response object containing the deleted cookie.

When the browser receives a response containing a forgotten cookie, it will automatically delete the cookie from local storage.

4. Summary

In this article, we learned about cookies and how to create and delete cookies in Laravel applications. The method of creating cookies is very simple, just use the Cookie class provided by the framework. When deleting cookies, you can specify the name of the cookie to be deleted by calling the forget() method provided by the Cookie class.
