private function auth(){
        
        if (isset($_SESSION['auth'])){
            $this->_sAuth = $_SESSION['auth'];
            return;
        }
        
        $aPost = array ( 'accountType'   => 'GOOGLE',
                         'Email'         => $this->_sUser,
                         'Passwd'        => $this->_sPass,
                         'service'       => 'analytics',
                         'source'        => 'SWIS-Webbeheer-4.0');
      
        $sResponse = $this->getUrl('https://www.google.com/accounts/ClientLogin',$aPost);
    
        $_SESSION['auth'] = '';
        if (strpos($sResponse, "\n") !== false){
            $aResponse = explode("\n", $sResponse);
            foreach ($aResponse as $sResponse){
                if (substr($sResponse, 0, 4) == 'Auth'){
                    $_SESSION['auth'] = trim(substr($sResponse, 5));
                }
            }
        }
        if ($_SESSION['auth'] == ''){
            unset($_SESSION['auth']);
            throw new Exception('Retrieving Auth hash failed!');
        }
        $this->_sAuth = $_SESSION['auth'];
    }

and then

Code:

private function getXml($sUrl){
        
        return $this->getUrl($sUrl, array(), array('Authorization: GoogleLogin auth=' . $this->_sAuth));
    }

hope it helps
