Import Google contacts in PHP

Question

I am trying to imports contacts from google to my webpage. I need to get the email address of the contacts from google account. I am referring this link . This code lists the email addresses of the contacts in the redirect url page.

Its expected to list the email addresses,But when I use this I'm not getting the expected results. I'm getting blank. Don't know where I've made the mistake.

Here is my code:

oauth.php

            <html>
            <head>
            <meta name="robots" content="noindex" />
            <title>Email address list - Import Google contacts</title>
            <style type="text/css">
            a:link {color:Chocolate;text-decoration: none;}
            a:hover {color:CornflowerBlue;}
            .logo{width:100%;height:110px;border:2px solid black;background-color:#666666;}
            </style>
            </head>
            <body>
            <br/>
            <br/>
            <div style="padding-left: 50px;">
            <?php
            $client_id='my_client_id';
            $client_secret='my_client_secret';
            $redirect_uri='my_redirect_url';
            $max_results = 25;

            $auth_code = $_GET["code"];

            function curl_file_get_contents($url)
            {

            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($curl, CURLOPT_AUTOREFERER, TRUE);  //To automatically set the Referer: field in requests where it follows a Location: redirect.
            curl_setopt($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.

            </div>
            </body>
            </html>

Can anyone help me to find where I've went wrong.

Before you import google contacts, you have to turn on the contacts API in the developer console.

The code I used here is fine. When I turned on Contacts API of my developers console, I got the email addresses of google contacts.
