ZF2 Cookies for affiliates - php

Question

I am attempting to write a cookie class to store referral information and need a bit of guidance.
The documentation on this seems a little sparse.
As with any affiliate programme, the idea is to grab information from a link: http://example.com/referrer_id=123 and to store this on the users computer for later use.
So this is what I have thus far:
Controller:
$cookieObject = new CookieService();
$cookieObject->setCookie(
[
'value' => [
'name' => 'test',
'referring_site'=>'test site'
]
]
);
die(var_dump($cookieObject->getCookie()));
CookieService class:
<?php
namespace Application\Library\Session;
use Zend\Http\Header\SetCookie;
use Zend\Http\Cookies;
class CookieService extends SetCookie
{
public function __construct() {
$this->cookie = new SetCookie();
$this->header = new Cookies();
}
/**
* Create a new cookie
* #param $params
*/
public function setCookie($params)
{
$key = (isset($params['key'])) ? $params['key'] : 'referrer';
$value = (isset($params['value'])) ? $params['value'] : [];
$expires = (isset($params['time'])) ? time() + $params['time'] : time() + 365 * 60 * 60 * 24;
/**
* Test whether the cookie exists before updating
*/
if (!$this->exists($key))
{
$this->cookie->setName($key);
$this->cookie->setValue($value);
$this->cookie->setExpires($expires);
$this->header->addCookie($this->cookie);
}
}
/**
* Get a cookie based on a given key
* #param string $key
* #return null
*/
public function getCookie($key = 'referrer')
{
$cookieArray = $this->header->getAllCookies();
foreach ($cookieArray AS $cookie)
{
if ($cookie->name === $key)
{
return $cookie;
}
}
return null;
}
/**
* Returns whether a cookie exists or not
* #param $key
* #return bool
*/
public function exists($key)
{
return ( $this->getCookie($key) ) ? true : false;
}
}
I am struggling with the following:
If I save a cookie then close the browser, the cookie is deleted. I can't seem to find any documentation that clearly covers this use.
Any advice, greatly appreciated.
ND: The dump of the cookie object:
object(Zend\Http\Header\SetCookie)[1085]
protected 'name' => string 'referrer' (length=8)
protected 'value' =>
array (size=2)
'name' => string 'test' (length=4)
'referring_site' => string 'test site' (length=9)
protected 'version' => null
protected 'maxAge' => null
protected 'expires' => int 1475931242
protected 'domain' => null
protected 'path' => null
protected 'secure' => boolean false
protected 'quoteFieldValue' => boolean false
protected 'httponly' => boolean false
public 'type' => string 'Cookie' (length=6)

Ok - so I have written my own class to deal with this. It is pretty simple:
<?php
namespace Application\Library\Session;
/**
* Use this service to set persistent cookies on a users machine
* Class CookieService
* #package Application\Library\Session
*/
class CookieService
{
/**
* Create a new cookie
* #param $params
*/
public function setCookie($params)
{
$name = (isset($params['name'])) ? $params['name'] : 'referrer';
$value = (isset($params['value'])) ? $params['value'] : '';
$expire = (isset($params['expire'])) ? time() + $params['expire'] : time() + 365 * 60 * 60 * 24;
$path = (isset($params['path'])) ? $params['path'] : '';
$domain = (isset($params['domain'])) ? $params['domain'] : '';
$secure = (isset($params['secure'])) ? $params['secure'] : 0;
$httponly = (isset($params['httponly'])) ? $params['httponly'] : 1;
/**
* Test whether the cookie exists before updating
*/
if (!$this->exists($name))
{
setcookie(
$name,
$value,
$expire ,
$path ,
$domain ,
$secure ,
$httponly
);
}
}
/**
* Get a cookie based on a given key
* #param string $name
* #return null
*/
public function getCookie($name = 'referrer')
{
return (isset($_COOKIE[$name])) ? $_COOKIE[$name] : null;
}
/**
* Returns whether a cookie exists or not
* #param $name
* #return bool
*/
public function exists($name)
{
return ( $this->getCookie($name) ) ? true : false;
}
/**
* Remove a cookie
* #param $name
*/
function deleteCookie($name)
{
if ($this->exists($name))
{
setcookie($name, "", time()-(60*60*24) );
}
}
}
