CCookieCollection

Package system.web
Inheritance class CCookieCollection » CMap » CComponent
Implements Traversable, Countable, ArrayAccess, IteratorAggregate
Since 1.0
Source Code framework/web/CHttpRequest.php
CCookieCollection implements a collection class to store cookies.

You normally access it via CHttpRequest::getCookies().

Since CCookieCollection extends from CMap, it can be used like an associative array as follows: 
$cookies[$name]=new CHttpCookie($name,$value); // sends a cookie
$value=$cookies[$name]->value; // reads a cookie value
unset($cookies[$name]);  // removes a cookie

Method Details

__construct() method
public void __construct(CHttpRequest $request)
$request CHttpRequest owner of this collection.
Source Code: framework/web/CHttpRequest.php#1451 (show)
public function __construct(CHttpRequest $request)
{
    $this->_request=$request;
    $this->copyfrom($this->getCookies());
    $this->_initialized=true;
}

Constructor.

add() method
public void add(mixed $name, CHttpCookie $cookie)
$name mixed Cookie name.
$cookie CHttpCookie Cookie object.
Source Code: framework/web/CHttpRequest.php#1497 (show)
public function add($name,$cookie)
{
    if($cookie instanceof CHttpCookie)
    {
        $this->remove($name);
        parent::add($name,$cookie);
        if($this->_initialized)
            $this->addCookie($cookie);
    }
    else
        throw new CException(Yii::t('yii','CHttpCookieCollection can only hold CHttpCookie objects.'));
}

Adds a cookie with the specified name. This overrides the parent implementation by performing additional operations for each newly added CHttpCookie object.

addCookie() method
protected void addCookie(CHttpCookie $cookie)
$cookie CHttpCookie cookie to be sent
Source Code: framework/web/CHttpRequest.php#1546 (show)
protected function addCookie($cookie)
{
    $value=$cookie->value;
    if($this->_request->enableCookieValidation)
        $value=Yii::app()->getSecurityManager()->hashData(serialize($value));
    if(version_compare(PHP_VERSION,'7.3.0','>='))
        setcookie($cookie->name,$value,$this->getCookieOptions($cookie));
    elseif(version_compare(PHP_VERSION,'5.2.0','>='))
        setcookie($cookie->name,$value,$cookie->expire,$cookie->path,$cookie->domain,$cookie->secure,$cookie->httpOnly);
    else
        setcookie($cookie->name,$value,$cookie->expire,$cookie->path,$cookie->domain,$cookie->secure);
}

Sends a cookie.

getCookieOptions() method
protected array getCookieOptions(CHttpCookie $cookie)
$cookie CHttpCookie
{return} array
Source Code: framework/web/CHttpRequest.php#1579 (show)
protected function getCookieOptions($cookie)
{
    return array(
        'expires'=>$cookie->expire,
        'path'=>$cookie->path,
        'domain'=>$cookie->domain,
        'secure'=>$cookie->secure,
        'httpOnly'=>$cookie->httpOnly,
        'sameSite'=>$cookie->sameSite
    );
}

Builds the setcookie $options parameter.

getCookies() method
protected array getCookies()
{return} array list of validated cookies
Source Code: framework/web/CHttpRequest.php#1469 (show)
protected function getCookies()
{
    $cookies=array();
    if($this->_request->enableCookieValidation)
    {
        $sm=Yii::app()->getSecurityManager();
        foreach($_COOKIE as $name=>$value)
        {
            if(is_string($value) && ($value=$sm->validateData($value))!==false)
                $cookies[$name]=new CHttpCookie($name,@unserialize($value));
        }
    }
    else
    {
        foreach($_COOKIE as $name=>$value)
            $cookies[$name]=new CHttpCookie($name,$value);
    }
    return $cookies;
}

getRequest() method

{return} CHttpRequest the request instance
Source Code: framework/web/CHttpRequest.php#1461 (show)
public function getRequest()
{
    return $this->_request;
}

remove() method
public CHttpCookie remove(mixed $name, array $options=array ( ))
$name mixed Cookie name.
$options array Cookie configuration array consisting of name-value pairs, available since 1.1.11.
{return} CHttpCookie The removed cookie object.
Source Code: framework/web/CHttpRequest.php#1528 (show)
public function remove($name,$options=array())
{
    if(($cookie=parent::remove($name))!==null)
    {
        if($this->_initialized)
        {
            $cookie->configure($options);
            $this->removeCookie($cookie);
        }
    }

    return $cookie;
}

Removes a cookie with the specified name. This overrides the parent implementation by performing additional cleanup work when removing a CHttpCookie object. Since version 1.1.11, the second parameter is available that can be used to specify the options of the CHttpCookie being removed. For example, this may be useful when dealing with ".domain.tld" where multiple subdomains are expected to be able to manage cookies: 

$options=array('domain'=>'.domain.tld');
Yii::app()->request->cookies['foo']=new CHttpCookie('cookie','value',$options);
Yii::app()->request->cookies->remove('cookie',$options);

removeCookie() method
protected void removeCookie(CHttpCookie $cookie)
$cookie CHttpCookie cookie to be deleted
Source Code: framework/web/CHttpRequest.php#1563 (show)
protected function removeCookie($cookie)
{
    $cookie->expire=0;
    if(version_compare(PHP_VERSION,'7.3.0','>='))
        setcookie($cookie->name,'',$this->getCookieOptions($cookie));
    elseif(version_compare(PHP_VERSION,'5.2.0','>='))
        setcookie($cookie->name,'',$cookie->expire,$cookie->path,$cookie->domain,$cookie->secure,$cookie->httpOnly);
    else
        setcookie($cookie->name,'',$cookie->expire,$cookie->path,$cookie->domain,$cookie->secure);
}

Deletes a cookie.
