使用Facebook PHP SDK 4找不到“Facebook \ GraphObject”类

Question

I want to connect my page with facebook and downloaded therefore the Facebook PHP SDK 4. Since the Facebook documentation and the GitHub page are not really well made, I have a question regarding my error message from the title.

I don't want to use Composer for PHP (which should be possible according to the Facebook documentation).

I followed the example on the Github page and included the Facebook PHP files into my PHP file with the following lines of code:

use Facebook\FacebookSession;
use Facebook\FacebookRequest;
use Facebook\GraphUser;
use Facebook\FacebookRequestException;
require_once( 'Facebook/FacebookSession.php' );
require_once( 'Facebook/FacebookRequest.php' );
require_once( 'Facebook/GraphUser.php' );
require_once( 'Facebook/FacebookRequestException.php' );

In the documentation there is nowhere mentioned that I have to include the require_once statement, I found that on stackoverflow.

Problem is now that even with the above (correct) implementation, I get an error which says 'Fatal error: Class 'Facebook\GraphObject' not found in ../fblogin2/Facebook/GraphUser.php on line 33'

I think in this class there is also no require_once statement, but I can't go through the whole SDK code and add the statements for Facebook. Shouldn't it work out-of-the-box? Are there some good tutorials for the SDK 4 or anything else, because I'm really stuck with the official facebook documentation and the short github example.

Answer 1

Now I found a good tutorial and solution for the Facebook SDK (v4) here.

It's 'funny' that a billion dollar company is not able to provide a decent documentation.
