Yahoo open id login api

Question

Im new to open id, but still i have tried to integrate the open id in my website. Im using yahoo provider to login in to my website. Could any help me in getting the user information like yahoo mail id , first name , last name.

I have take the below code from a website which is provided for google, i have changed the provider to yahoo

Code which i have tried:

<?php
# Logging in with Google accounts requires setting special identity, so this example shows how to do it.
require 'openid.php';
try {
# Change 'localhost' to your domain name.
$openid = new LightOpenID('localhost');
if(!$openid->mode) {
if(isset($_GET['login'])) {
$openid->identity = 'https://me.yahoo.com';
header('Location: ' . $openid->authUrl());
}
?>
<form action="?login" method="post">
<button>Login with Yahoo</button>
</form>
<?php
} elseif($openid->mode == 'cancel') {
echo 'User has canceled authentication!';
} else {
echo 'User ' . ($openid->validate() ? $openid->identity . ' has ' : 'has not ') . 'logged in.';
print_r($openid->ax_to_sreg);
}
} catch(ErrorException $e) {
echo $e->getMessage();
}

Here is the modified code :

<?php


require 'openid.php';

try
{
    # Change 'localhost' to your domain name.
    $openid = new LightOpenID($_SERVER['HTTP_HOST']);

    //Not already logged in
    if(!$openid->mode)
    {

        //do the login
        if(isset($_GET['login']))
        {
            //The google openid url
            $openid->identity = 'https://me.yahoo.com';

            //Get additional google account information about the user , name , email , country
            $openid->required = array('contact/email' , 'namePerson/first' , 'namePerson/last' , 'pref/language' , 'contact/country/home');

            //start discovery
            header('Location: ' . $openid->authUrl());
        }
        else
        {
            //print the login form
            login_form();
        }

    }

    else if($openid->mode == 'cancel')
    {
        echo 'User has canceled authentication!';
        //redirect back to login page ??
    }

    //Echo login information by default
    else
    {
        if($openid->validate())
        {
            //User logged in
            $d = $openid->getAttributes();

            $first_name = $d['namePerson/first'];
            $last_name = $d['namePerson/last'];
            $email = $d['contact/email'];
            $language_code = $d['pref/language'];
            $country_code = $d['contact/country/home'];

            $data = array(
                'first_name' => $first_name ,
                'last_name' => $last_name ,
                'email' => $email ,
            );

            //now signup/login the user.
            print_r($data);
        }
        else
        {
            //user is not logged in
        }
    }
}

catch(ErrorException $e)
{
    echo $e->getMessage();
}
