Google Plus API Authenticated User - php

Question

I have used the following code to authenticate a user (it is based off of googles examples of a services account on github):
<?php
//API INFORMATION
$client_id='xx-x.apps.googleusercontent.com';
$client_email='xx-xx#developer.gserviceaccount.com';
$client_key='xx';
$cert_loc='directory/google-api-bushbase-privatekey.p12';
//SET THE APP SCROPES
$scopes=array(
'https://www.googleapis.com/auth/plus.login',
'https://www.googleapis.com/auth/plus.me',
'https://www.googleapis.com/auth/userinfo.email',
'https://www.googleapis.com/auth/userinfo.profile'
);
//GET ASSERTION CREDENTIALS
if(($key=file_get_contents($cert_loc))!==false){
//GOT GOOGLE CERTIFICATE
try{
$auth= new Google_Auth_AssertionCredentials($client_email,$scopes,$key);
}catch (Exception $e){
echo $error;
echo 'Unable to get authenticate with Google servers</div>';
//RETURN FALSE
return false;
}
}else{
echo $error;
echo 'Unable to get Google certificate</div>';
//RETURN FALSE
return false;
}
//GOOGLE CONNECTION OBJECT
try {
$connection = new Google_Client();
$connection->setApplicationName("Bush Base");
$connection->setAssertionCredentials($auth);
//CHECK TO SEE IF TOKEN IS EXPIRED VIA SESSION
if (isset($_SESSION['service_token'])) {
$connection->setAccessToken($_SESSION['service_token']);
}
if($connection->getAuth()->isAccessTokenExpired()){
//TOKEN IS EXPIRED SO RESET WITH ASSERTION CRED
$connection->getAuth()->refreshTokenWithAssertion($auth);
}
//GET THE TOKEN VALUE
$_SESSION['service_token']=$connection->getAccessToken();
$connection->setAccessToken($_SESSION['service_token']);
//THE CONNECTION WAS NOT SUCCESSFUL
}catch (Exception $e){
echo $error;
echo 'Unable to connect with Google database</div>';
//RETURN FALSE
return false;
}
//CREATE THE NEW GOOGLE SERVICES OBJECT
try{
$info =new Google_Service_Plus($connection);
}catch (Exception $e){
echo $error;
echo 'Unable to conntect to google services</div>';
//RETURN FALSE
return false;
}
try{
//GET THE USER INFO
$data= $info->people->get('me');
echo "<pre>";
print_r($data);
echo "</pre>";
}
