Is there a better way to fetch OpenID infos from provider?

Question

Hi,

I am very new to the OpenID logic, so please excuse me if I am asking something trivial. I am using the OpenID component for CakePHP by Cakebaker, with the PHP OpenID library by JanRain.

It's all working quite well, but I could not find an exhaustive way to retrieve user informations depending on provider and method (sreg vs. ax). So this is what I came up with:

if ($axResponse) {
    if (is_array($a = $axResponse->get('http://axschema.org/contact/email'))) {
        $user_record['email'] = $a[0];
        if (is_array($b = $axResponse->get('http://axschema.org/namePerson'))) {
            $user_record['nickname'] = $b[0];
        }
    } else if (is_array($a = $axResponse->get('http://schema.openid.net/contact/email'))) {
        $user_record['email'] = $a[0];
        if (is_array($b = $axResponse->get('http://schema.openid.net/namePerson'))) {
            $user_record['nickname'] = $b[0];
        }
    }
} else if ($sreg) {
    if (isset($sreg['email'])) {
        $user_record['email'] = $sreg['email'];
    }
    if (isset($sreg['nickname'])) {
        $user_record['nickname'] = $sreg['nickname'];
    }
}

Although I tested it successfully with Google, Yahoo! and AOL's OpenID, I'm sure I would run into trouble with other / smaller providers. Is there a better and nicer way to achieve the same result? This seems particularly flawed if I try to fetch other optional fields...

Thanks for your input and suggestions!
