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

if(version_compare(PHP_VERSION,'5.2.0','>='))
setcookie($cookie->name,$value,$cookie->expire,$cookie->path,$cookie->domain,$cookie->secure,$cookie->httpOnly);
else

$cookies[$name]=newCHttpCookie($name,@unserialize($value));
}
}
else
{
foreach($_COOKIEas$name=>$value)

}
return$cookies;
}
getRequest() 方法

}
return$cookie;
}

Removes a cookie with the specified name. This overrides the parent implementation by performing additional cleanup work when removing a CHttpCookie object.

removeCookie() 方法
protected void removeCookie(CHttpCookie $cookie)
$cookieCHttpCookiecookie to be deleted
源码: framework/web/CHttpRequest.php#1057 (显示) protectedfunctionremoveCookie($cookie)
