Cannot update user information using Google PHP API Client library - php

Question

I am trying to update user phone numbers on Google Apps Directory. Currently I have the API able to retrieve information on user's but when I try to set their phone numbers it just silently fails. The values do not update in the directory. It is possible I may be just missing a method that actually sends the data but I have been unable to find such a method.
My current scopes are:
$scopes = array('https://www.googleapis.com/auth/admin.directory.user', 'https://www.googleapis.com/auth/admin.directory.group', 'https://www.googleapis.com/auth/admin.directory.orgunit');
My attempts at saving phone numbers have been varied. I have tried:
$work_phone = new \Google_Service_Directory_UserPhone();
$work_phone->setType('work');
$work_phone->setValue($work_number);
$google_user->setPhones(array($work_phone));
And
$google_user->setPhones(array(array(
"type"=>"work",
"value"=>$work_number
)));
As well as a variety of values for the type array structures. Any help would be greatly appreciated.

In order to update the phone number in the directory, you need to send the information back to Google. With your code:
$google_user->setPhones(array($work_phone));
You are setting the object's phones array correctly. You still need to update that user however. You were correct when you said:
I may be just missing a method that actually sends the data
You would need to do something like this:
$work_phone = new \Google_Service_Directory_UserPhone();
$work_phone->setType('work');
$work_phone->setValue($work_number);
$google_user->setPhones(array($work_phone));
$serviceDirectory = new Google_Service_Directory($client);
$serviceDirectory->users->update($google_user);
