FIG Cookies

Managing Cookies for PSR-7 Requests and Responses. It is fork from dflydev/dflydev-fig-cookies

Requirements

• PHP 7.1+
• psr/http-message

Installation

$> composer require phpcraftdream/figcookies

Concepts

Instantiating these collections looks like this:

use PHPCraftdream\FigCookies\Cookies;

// Get cookies from request
$cookies = (new Cookies)->fromRequest($request);

// Get cookies from response
$cookies = (new Cookies)->fromResponse($response);

After modifying these collections in some way, they are rendered into a PSR-7 Request or PSR-7 Response like this:

// Render the Cookie headers and add them to the headers of a
// PSR-7 Request.
$request = $cookies->toRequest($request);

// Render the Set-Cookie headers and add them to the headers of a
// PSR-7 Response.
$response = $cookies->toResponse($response);

Basic Usage

Get a Request Cookie

The get method will return a Cookie instance. If no cookie by the specified name exists, the returned Cookie instance will have new empty Cookie instance.

use PHPCraftdream\FigCookies\Cookies;

$cookie = (new Cookies)->fromRequest($request)->get('theme');
$cookie->isNew(); //true if no cookie by the specified name exists
//...
$cookie->getValue();

Set a Request Cookie

The set method will either add a cookie or replace an existing cookie.

The Cookie primitive is used as the second argument.

use PHPCraftdream\FigCookies\Cookies;

$cookies = (new Cookies)->fromRequest($request);
$cookies->get('theme')->setValue('acme');

$request = $cookies->toRequest($request);

Remove a Request Cookie

The remove method removes a cookie if it exists.

use PHPCraftdream\FigCookies\Cookies;

$cookies = (new Cookies)->fromRequest($request);
$cookies->delete('theme');
$request = $cookies->toRequest($request);

Create cookie

use PHPCraftdream\FigCookies\Cookie;

$cookie = (new Cookie('lu'))
	->setValue('Rg3vHJZnehYLjVg7qi3bZjzg')
	->setExpires('Tue, 15-Jan-2013 21:47:38 GMT')
	->setMaxAge(500)
	->rememberForever()
	->setPath('/')
	->setDomain('.example.com')
	->setSecure(true)
	->setHttpOnly(true)
;

Get a Response Cookie

use PHPCraftdream\FigCookies\Cookies;

$cookies = (new Cookies)->fromResponse($response);
$cookie = $cookies->get('theme');

Set a Response Cookie

The add method will either add a cookie or replace an existing cookie.

use PHPCraftdream\FigCookies\Cookie;
use PHPCraftdream\FigCookies\Cookies;

$cookies = (new Cookies)->fromResponse($response);

$response = $cookies
	->add(
		(new Cookie('token'))
		->setValue('a9s87dfz978a9')
		->setDomain('example.com')
		->setPath('/firewall')
	)
	->toResponse($response);

Modify a Response Cookie

use PHPCraftdream\FigCookies\Cookies;

$cookies = (new Cookies)->fromResponse($response);

$cookie = $cookies->get('visitCount');
$cookie->setValue($cookie->getValue() + 1);

$response = $cookies->toResponse($response);

Remove a Response Cookie

The delete method removes a cookie from the response if it exists.

use PHPCraftdream\FigCookies\Cookies;

$response = (new Cookies)
				->fromResponse($response)
				->delete('theme')
				->toResponse($response);

Expire a Response Cookie

The expire method sets a cookie with an expiry date in the far past. This causes the client to remove the cookie.

use PHPCraftdream\FigCookies\Cookies;

$cookies = (new Cookies)->fromResponse($response);
$cookies->get('session_cookie')->expire();
$response = $cookies->toResponse($response);

FAQ

Do you call setcookies?

No.

Delivery of the rendered Cookies instances is the responsibility of the PSR-7 client implementation.

Do you do anything with sessions?

No.

It would be possible to build session handling using cookies on top of FIG Cookies but it is out of scope for this package.

Do you read from $_COOKIES?

No.

FIG Cookies only pays attention to the Cookie headers on PSR-7 Request instances.
