Q	A
Version(s)	2.19.0

Summary

When attempting to serialize the cookies using the documentation on the /laminas-http/client/cookies/#serializing-and-caching-cookies page, I get the following error:

PHP Fatal error: Uncaught Error: Call to undefined method Laminas\Http\Header\SetCookie::__toString()

on Line 270 of /laminas/laminas-http/src/Cookies.php

How to reproduce

Code:

$client = new Client();
$headers = $client->getRequest()->getHeaders();
$cookies = new Laminas\Http\Cookies($headers);

$client->setUri(_redacted_);
$client->setParameterPost(['login' => '_redacted_', 'pwd' => '_redacted_']);
$client->setMethod('POST');

$response = $client->getResponse();
$cookies->addCookiesFromResponse($response, $client->getUri());
$cookiesToCache = $cookies->getAllCookies($cookies::COOKIE_STRING_CONCAT);

Expected behavior

The $cookiesToCache variable should have the serialized string.

This bug was never discovered and this apparently never worked since call to __toString() present since 2.0.0 and header never had __toString() in stable releases.

@kjdfjhdjkh I would recommend to utilize PSR-18 http client instead of this library.
