Introduction:
Cookies are an essential component of modern web applications, enabling developers to store and retrieve data on the client-side. Laravel, a popular PHP framework, provides a simple and efficient way to manage cookies. In this blog post, we’ll delve into Laravel cookies and explore how to write, read, update, and delete cookies within your Laravel applications.

  1. Writing Cookies:
    Writing a cookie in Laravel is a straightforward process. The response() helper function allows us to set a cookie in the HTTP response. Here’s an example:
use Illuminate\Http\Response;

public function setCookie()
{
    $cookie = cookie('name', 'John Doe', 60); // Name, value, expiration time (in minutes)

    return response('Cookie has been set.')->cookie($cookie);
}

In this example, we create a cookie named ‘name’ with the value ‘John Doe’, which will expire after 60 minutes. The cookie() function creates a new Cookie instance.

  1. Reading Cookies:
    Laravel provides an easy way to retrieve cookie values. The Illuminate\Http\Request instance provides the cookie() method to access the cookie’s value. Here’s an example:
use Illuminate\Http\Request;

public function getCookie(Request $request)
{
    $value = $request->cookie('name');

    return "Cookie value: " . $value;
}

In this example, we retrieve the value of the ‘name’ cookie using the cookie() method. The value is then returned for further processing.

  1. Updating Cookies:
    To update a cookie, you can create a new cookie with the updated value and expiration time. Use the same name as the existing cookie, and Laravel will automatically overwrite it. Here’s an example:
use Illuminate\Http\Response;

public function updateCookie()
{
    $cookie = cookie('name', 'Jane Smith', 120); // Updated name and expiration time

    return response('Cookie has been updated.')->cookie($cookie);
}

In this example, we create a new cookie with the updated name ‘Jane Smith’ and an extended expiration time of 120 minutes. By setting the cookie with the same name, Laravel will update the existing cookie.

  1. Deleting Cookies:
    To delete a cookie, you need to create a cookie with the same name and set its expiration time in the past. This instructs the client browser to remove the cookie. Here’s an example:
use Illuminate\Http\Response;

public function deleteCookie()
{
    $cookie = cookie()->forget('name'); // Cookie to be deleted

    return response('Cookie has been deleted.')->cookie($cookie);
}

In this example, we use the forget() method to create a cookie that instructs the browser to delete the ‘name’ cookie by setting its expiration time to the past.

Conclusion:
Laravel offers convenient methods for managing cookies within your web applications. By understanding how to write, read, update, and delete cookies using Laravel, you can enhance your application’s functionality and improve the user experience. Whether it’s storing user preferences or managing authentication tokens, cookies play a crucial role in web development.
