Started on: 13 February 13
In Gmail i want to get my friends email address using the Gmail Contacts API version 3.

Actually i am using this API https://developers.google.com/google-apps/contacts/v3

I used the OAuth method , refer the below code
$auth_code = $_GET["code"];

function curl_file_get_contents($url)
{
$curl = curl_init();
//$userAgent = 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322)';

curl_setopt($curl,CURLOPT_URL,$url); //The URL to fetch. This can also be set when initializing a session with curl_init().
curl_setopt($curl,CURLOPT_RETURNTRANSFER,TRUE); //TRUE to return the transfer as a string of the return value of curl_exec() instead of outputting it out directly.
curl_setopt($curl,CURLOPT_CONNECTTIMEOUT,5); //The number of seconds to wait while trying to connect.

//curl_setopt($curl, CURLOPT_USERAGENT, $userAgent); //The contents of the "User-Agent: " header to be used in a HTTP request.
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, TRUE); //To follow any "Location: " header that the server sends as part of the HTTP header.
curl_setopt($curl, CURLOPT_AUTOREFERER, TRUE); //To automatically set the Referer: field in requests where it follows a Location: redirect.
curl_setopt($curl, CURLOPT_TIMEOUT, 10); //The maximum number of seconds to allow cURL functions to execute.
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE); //To stop cURL from verifying the peer's certificate.

$contents = curl_exec($curl);
curl_close($curl);
return $contents;
}

$fields=array(
'code'=> urlencode($auth_code),
'client_id'=> urlencode($client_id),
'client_secret'=> urlencode($client_secret),
'redirect_uri'=> urlencode($redirect_uri),
'grant_type'=> urlencode('authorization_code')
);
$post = '';
foreach($fields as $key=>$value) { $post .= $key.'='.$value.'&'; }
$post = rtrim($post,'&');

$curl = curl_init();
curl_setopt($curl,CURLOPT_URL,'https://accounts.google.com/o/oauth2/token');
curl_setopt($curl,CURLOPT_POST,5);
curl_setopt($curl,CURLOPT_POSTFIELDS,$post);
curl_setopt($curl, CURLOPT_RETURNTRANSFER,TRUE);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER,FALSE);
$result = curl_exec($curl);
curl_close($curl);

$response = json_decode($result);
$accesstoken = $response->access_token;

$url = 'https://www.google.com/m8/feeds/contacts/default/full?max-results='.$max_results.'&oauth_token='.$accesstoken;
echo $url;
$xmlresponse = curl_file_get_contents($url);
if((strlen(stristr($xmlresponse,'Authorization required'))>0) && (strlen(stristr($xmlresponse,'Error '))>0)) //At times you get Authorization error from Google.
{
echo "<h2>OOPS !! Something went wrong. Please try reloading the page.</h2>";
exit();
}
echo "<h3>Email Addresses:</h3>";
$xml = new SimpleXMLElement($xmlresponse);
$xml->registerXPathNamespace('gd', 'http://schemas.google.com/g/2005');
$result = $xml->xpath('//gd:email');

foreach ($result as $title) {
echo $title->attributes()->address . "<br>";
}
