Using Google authentication API with PHP

Instead of printing the userinfo, the following code is printing the details of the access token granted by Google. The code is very simple yet I am not able to figure out the exact cause of this

    <?php
$url = 'https://accounts.google.com/o/oauth2/token';
$fields = array(
        'code'=>urlencode($_GET['code']),
        'client_id'=>urlencode('###########.apps.googleusercontent.com'),
        'client_secret'=>urlencode('###########'),
        'redirect_uri'=>urlencode('http://######odie.co.in/googlogin'),
        'grant_type'=>urlencode('authorization_code'),
                    );


foreach($fields as $key=>$value) {
     $fields_string .= $key.'='.$value.'&';
     }
rtrim($fields_string,'&');

//open connection
$ch = curl_init();

//set the url, number of POST vars, POST data
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_POST,count($fields));
curl_setopt($ch,CURLOPT_POSTFIELDS,$fields_string);

//execute post
$result = curl_exec($ch);


//close connection
curl_close($ch);
$data =  json_decode($result);

print_r(file_get_contents(' https://www.googleapis.com/oauth2/v1/userinfo?access_token='.$data['access_token']));
?>

You need to add CURLOPT_RETURNTRANSFER, true to your curl_setopt.

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
