README

This package provides CookieFactory, a PSR-7 compatible class that facilitates creating Set-cookie headers.

To install, with composer use:

composer require myelophone/cookies-psr7

or add myelophone/cookies-psr7 to your project's composer.json:

{
	"require": {
		"myelophone/cookies-psr7": "^1.0"
	}
}

Example

Use a CookieFactory to create the values for Set-cookie headers.

<?php

use Myelophone\Cookies\CookieFactory;

$cookieFactory = new CookieFactory();

$cookie = $cookieFactory->create('name', 'value');
// name=value

Use these with the PSR-7 ResponseInterface->withAddedHeader (ResponseInterface->withHeader or etc) to add cookies to a response.

$response = $response->withHeader('Set-cookie', $cookieFactory->create('name', 'value'));

To configure a CookieFactory to provide Domain, Path, Secure, HttpOnly and/or SameSite, pass these to the contructor.

$cookieFactory = new CookieFactory(
  'www.example.com', // Domain
  '/', // Path
  true, // Secure
  true, // HttpOnly
  'Strict' //SameSite
);

$cookie = $cookieFactory->create('name', 'value');
// name=value; Domain=www.example.com; Path=/; Secure; HttpOnly; SameSite=Strict

Expires and Max-Age

By default, create() will make session cookies that expire when the user closes the browser. To create a persistant cookie, provide the expiration as the third argument. This argument can several forms:

Numeric values are read as seconds for Max-Age.

$cookie = $cookieFactory->create('name', 'value', 3600);
// name=value; Max-Age=3600

Use a DateTime instance to set a specific expiration time. Note that CookieFactory will convert this DateTime to an HTTP-date in the format <day-name>, <day> <month> <year> <hour>:<minute>:<second> GMT in accordance with RFC7321.

$cookie = $cookieFactory->create('name', 'value', new DateTime('31-Dec-2018 23:00:00 EST'));
// name=value; Expires=Tue, 01 Jan 2019 04:00:00 GMT

You may also provide a string which will be used as-is for the expiration. When you provide a string, you are responsible for formatting the date.

$cookie = $cookieFactory->create('name', 'value', new DateTime('Tue, 01 Jan 2019 04:00:00 GMT'));
// name=value; Expires=Tue, 01 Jan 2019 04:00:00 GMT

Removing Cookies

To remove a cookie, use the remove method to create a Set-cookie header that sets the value for the cookie to an empty string and sets the expiration to a date in the past.

$cookie = $cookieFactory->remove('name');
// name=; Expires=Thu, 01 Jan 1970 00:00:00 GMT
