The drewlabs/cookie library provide a cookie an Object Oriented component for building and parsing cookies. The library also provides various immutable methods on the Cookie instance to update cookie instance once created.

Usage

The library provides developers with a factory class for creating cookie instances. Using cookie factory class to create cookies follow the syntaxes below:

<?php

use Drewlabs\Cookie\Factory;

// Creates a session cookie with name and value as first parameters
$cookie = Factory::new()->create('sessionId',uniqid('session').time(), 0);

Using the factory class developers can create cookie instance from raw cookie string:

use Drewlabs\Cookie\Factory;

$expiresAt = (new \DateTimeImmutable())->format('U');
$cookie = Factory::new()->createFromString("sessionId=e8bb43229de9; Expires=$expiresAt; Domain=foo.example.com; Path=/; Secure; HttpOnly");

Note using the factory class is the recommended way to create cookie instance, but you can use Cookie class constructor to create cookie instances. The constructor takes the same parameters as the Factory::create() method. Consult the documentation reference for more information about supported parameters.

Basic Cookie API

After cookie instances are created, you can modify their value by creating modified instance of the cookie. To prevent OOP issue related to internal state changes, the cookie API does not directly modify their internal state... instead, it provide method for creating modified copy of the the source instance. Here is a list of methods for updating cookie instances values:

withValue

<?php
$cookie = Factory::new()->create('id', "oldCookieValue");

$cookie2 = $cookie->withValue("newCookieValue");

echo $cookie->getValue(); // oldCookieValue
echo $cookie2->getValue(); //newCookieValue

withDomain

The withDomain method allow you update the domain for which cookie was generated.

<?php
$cookie = Factory::new()->create('id', uniqid('cookie').time());
$cookie2 = $cookie->withDomain("com.azlabs.xyz");

echo $cookie->getDomain(); // null
echo $cookie2->getDomain(); //com.azlabs.xyz

withPath

The withPath method updates the url path on which cookie might be applied.

<?php
$cookie = Factory::new()->create('id', uniqid('cookie').time());
$cookie2 = $cookie->withPath("/auth");

echo $cookie->getPath(); // /
echo $cookie2->getPath(); // /auth

withHttpOnly withHttpOnly update the cookie to be only send through http header and not be modified by any frontend code. It tell browsers to enforce cookie rules and protect cookie againt frontend attacks.
```
$cookie = Factory::new()->create('id', uniqid('cookie').time());
$cookie2 = $cookie->withHttpOnly();
```

withSecure withSecure enforce cookie rules, by forcing browsers to send cookie though a secure connection.

<?php
$cookie = Factory::new()->create('id', uniqid('cookie').time());
$cookie2 = $cookie->withSecure();

__toString() cookie insances API also provides a __toString() method that allows you to convert cookie object to it string representation that can be used as value to Set-Cookie header.
