Facebook Php Api basics - php

Question

Im getting started with the php sdk, and struggling to understand a few things (I have a basic example below - but everytime the pic goes to MY wall and not the fan page)
Code:
require_once("facebook.php"); // set the right path
$config = array();
$config['appId'] = 'app id';
$config['secret'] = 'app secret';
$config['fileUpload'] = true; // optional
$fb = new Facebook($config);
$params = array(
// this is the access token for Fan Page
"access_token" => "I create this via the graph api (select App and click get token), I select publish stream and photo_upload permissions.",
"message" => "test message",
"source" => "#" ."photo.png", // "#" .
);
try {
// **** is Facebook id of Fan page
$ret = $fb->api('/****/photos', 'POST', $params);
echo 'Photo successfully uploaded to Facebook Album';
} catch(Exception $e) {
echo $e->getMessage();
}
the picture keeps going to MY wall (logged in user) and not the fan page, is that because im getting a token for the currently logged in user (me) instead of the fan page? and if so how do i generate a token for the fan page whilst logged in as the developer? (is it by putting the fan page id into the Get bar?)
Apologies for the noob questions but the facebook documentation sucks (until u understand the core functionality of course). Most tutorials work once u know how to use the graph API - none ive looked actually EXPLAIN how to use the graph to generate correct tokens, etc.

Answer 1

\POST /<ID>/photos — this will post on the <ID>'s wall only, so please double-check the <ID> that you are using.
The access token will depict that on behalf of whom the photo would be posted on the <ID>'s wall. If you use the user access token, the photo will be published on behalf of the user and if page access token is used, it will be published on the page's behalf itself.
You can get the page access token of your pages by-
\GET /me/accounts?fields=access_token
(permission required: manage_pages)
