__construct()

CAS_Client::__construct	(		$server_version,
			$proxy,
			$server_hostname,
			$server_port,
			$server_uri,
			$changeSessionID = true
	)

CAS_Client constructor.

Parameters

string	$server_version	the version of the CAS server
bool	$proxy	true if the CAS client is a CAS proxy
string	$server_hostname	the hostname of the CAS server
int	$server_port	the port the CAS server is running on
string	$server_uri	the URI the CAS server is responding on
bool	$changeSessionID	Allow phpCAS to change the session_id (Single Sign Out/handleLogoutRequests is based on that change)

Returns

a newly created CAS_Client object
