Copy google doc spreadsheet using php api - php

Question

I want to copy Google Doc spreadsheet file.This code I am using
function copyFile($service, $originFileId, $copyTitle) {
$copiedFile = new Google_DriveFile();
$copiedFile->setTitle($copyTitle);
try {
return $service->files->copy($originFileId, $copiedFile);
} catch (Exception $e) {
print "An error occurred: " . $e->getMessage();
}
return NULL;
}
require_once 'google-api-php-client/src/Google_Client.php';
require_once 'google-api-php-client/src/contrib/Google_DriveService.php';
$client = new Google_Client();
// Get your credentials from the console
$client->setClientId('myclientid');
$client->setClientSecret('myclient secret');
$client->setRedirectUri('urn:ietf:wg:oauth:2.0:oob');
$client->setScopes(array('https://www.googleapis.com/auth/drive'));
$service = new Google_DriveService($client);
copyFile($service,'my schema id','Copy Of Schema');
I am not able to get $service instance. SO I searched and get the above way to do but now it is giving 401 login required error.
Please help me

You need to check for sufficient authorization from the user
you need to generate authorization URL:
$authUrl = $client->createAuthUrl();
Redirect user to the authUrl
Make user paste the authorization code:
$authCode = trim(fgets(STDIN));
Authenticate
$accessToken = $client->authenticate($authCode);
$client->setAccessToken($accessToken);
Once above it done, you have now authenticated the user with OAuth to access drive.
