In Laravel, cookies are used to store data on the client-side browser. Laravel provides a convenient way to manage cookies using the Illuminate\Cookie package.

Here’s an overview of working with cookies in Laravel:

Setting a Cookie: You can set a cookie using the cookie helper function or the Response instance. For example:

// Using the cookie helper
cookie('name', 'value', $minutes);

// Using the Response instance
$response = new Response('Hello');
$response->cookie('name', 'value', $minutes);

The cookie helper function accepts three arguments: name, value, and expiration time in minutes. Illuminate\Session

Getting a Cookie Value: You can retrieve the value of a cookie using the cookie helper function or the Request instance. For example:

// Using the cookie helper
$value = cookie(‘name’);

// Using the Request instance
$value = $request->cookie(‘name’);

Attaching Cookies to Responses:
When sending a response, you can attach cookies using the withCookie method on the Response instance. For example:

return response('Hello')->withCookie(cookie('name', 'value', $minutes));

Forgetting a Cookie:
To remove a cookie, you can use the forget method on the Response instance. For example:

return response('Hello')->withCookie(cookie()->forget('name'));

This will set the cookie with an expiration date in the past, effectively deleting it from the client-side browser.
