        // retrieve Name and email address

        $return[] = array(
            'name' => $contact['title']['$t'],
            'email' => $contact['gd$email'][0]['address'],
            'img_url' => '//cdn.twkcdn.com/profile/image/avatar.png?w=40&h=40&cf',
        );
        }
      else
        {

        // retrieve Name and email address

        $return[] = array(
            'name' => $contact['title']['$t'],
            'email' => $contact['gd$email'][0]['address'],
            'img_url' => $url,
        );
        }
    }

$google_contacts = $return; //returning all d
}

This is just example of half script & i don't know why fetching contacts from google take about 15 to 20 seconds everytime i visit this page

Answer 1

Google doesn't check that all entry has email address.

Add that immediatly after Foreach :

if (!array_key_exists('gd$email', $contact)){
    continue;
}
