Methods

__construct(string $loginUrl = null, string $trustUrl = null, \Zend_OpenId_Provider_User $user = null, \Zend_OpenId_Provider_Storage $storage = null, integer $sessionTtl = 3600) : void

Constructs a Zend_OpenId_Provider object with given parameters.

Parameters

Name	Type	Description
$loginUrl	string	is an URL that provides login screen for end-user (by default it is the same URL with additional GET variable openid.action=login)
$trustUrl	string	is an URL that shows a question if end-user trust to given consumer (by default it is the same URL with additional GET variable openid.action=trust)
$user	\Zend_OpenId_Provider_User	is an object for communication with User-Agent and store information about logged-in user (it is a Zend_OpenId_Provider_User_Session object by default)
