Google API - get contacts mail - php

Question

I want to get full contact lists with emails of my friends.
I can get the list of contacts but not having emails.
Here is my code:
require_once APPPATH . 'vendor/google/src/Google_Client.php';
require_once APPPATH . 'vendor/google/src/contrib/Google_Oauth2Service.php';
$client = new Google_Client();
$client->setApplicationName("PHP Google Test");
$client->setClientId('xxx');
$client->setClientSecret('xxx');
$client->setRedirectUri('http://www.domain.xx/admin/others/google?test');
$client->setScopes("http://www.google.com/m8/feeds/");
$oauth2 = new Google_Oauth2Service($client);
if (isset($_GET['code'])) {
$client->authenticate();
$_SESSION['token'] = $client->getAccessToken();
$redirect = 'http://www.domain.xx/admin/others/google';
header('Location: ' . filter_var($redirect, FILTER_SANITIZE_URL));
}
if (isset($_SESSION['token'])) {
$client->setAccessToken($_SESSION['token']);
}
if (isset($_REQUEST['logout'])) {
unset($_SESSION['token']);
$client->revokeToken();
}
if ($client->getAccessToken()) {
$req = new Google_HttpRequest("https://www.google.com/m8/feeds/contacts/default/full");
$val = $client->getIo()->authenticatedRequest($req);
$response = json_encode(simplexml_load_string($val->getResponseBody()));
print "<pre>" . print_r(json_decode($response, true), true) . "</pre>";
$_SESSION['token'] = $client->getAccessToken();
} else {
$auth = $client->createAuthUrl();
}
$auth = $client->createAuthUrl();
echo '' . $auth . '';
How can i get email from contacts list?

Answer 1

I have solution:
Code:
$response = json_encode(simplexml_load_string($val->getResponseBody()));
print "<pre>" . print_r(json_decode($response, true), true) . "</pre>";
Change to:
$xml = simplexml_load_string($val->getResponseBody());
$xml->registerXPathNamespace('gd', 'http://schemas.google.com/g/2005');
$output_array = array();
foreach ($xml->entry as $entry) {
foreach ($entry->xpath('gd:email') as $email) {
$output_array[] = array((string)$entry->title, (string)$email->attributes()->address);
}
}
print_r($output_array);

you can make use of the Contact Kind from gdata components in Google Contact APIs
Assuming $response is the response you've got from the request to Google contact:
$xml= new SimpleXMLElement($response);
$xml->registerXPathNamespace('gd', 'http://schemas.google.com/g/2005');
$result = $xml->xpath('//gd:email');
