Facebook PHP SDK v5 Post to Fan Page - php

Question

I would like to use the Facebook PHP SDK v5 to automatically post to a FAN PAGE. I have the code below which successfully posts to my own wall, but how do I alter the code to post to my fan page? From what I've read, I need to pass in the page id of the fan page?
$params["message"] = 'test';
$params["link"] = 'https://example.com';
$params["picture"] = 'https://example.com/images/logo_hod.jpg';
$params["description"] = 'testtt';
$access_token = $accessToken;
try {
$response = $fb->post('/me/feed', $params, $access_token);
} catch(Facebook\Exceptions\FacebookResponseException $e) {
echo 'Graph returned an error: ' . $e->getMessage();
exit;
} catch(Facebook\Exceptions\FacebookSDKException $e) {
echo 'Facebook SDK returned an error: ' . $e->getMessage();
exit;
}
$graphNode = $response->getGraphNode();
echo 'Posted with id: ' . $graphNode['id'];
I tried replacing this line:
$response = $fb->post('/me/feed', $params, $access_token);
with this to substitute in the fan page id:
$response = $fb->post('/229107363768165/feed', $params, $access_token);
and got the error:
Graph returned an error: Unsupported post request.
UPDATE: I also made the app "public" in an attempt to get past the "unsupported post request" error. No luck.

i think your $params is not right.
I use this:
$fb = new Facebook\Facebook([
'app_id' => '{app-id}',
'app_secret' => '{app-secret}',
'default_graph_version' => 'v2.2',
]);
$params = [
'link' => 'https://example.com',
'photo' => 'https://example.com/images/logo_hod.jpg',
'message' => 'A test post!',
];
try {
// Returns a `Facebook\FacebookResponse` object
$response = $fb->post('/me/feed', $params, '{access-token}');
} catch(Facebook\Exceptions\FacebookResponseException $e) {
echo 'Graph returned an error: ' . $e->getMessage();
exit;
} catch(Facebook\Exceptions\FacebookSDKException $e) {
echo 'Facebook SDK returned an error: ' . $e->getMessage();
exit;
}
Post Links Using the Graph API
I assumes that you've already obtained an access token and the access token must have the publish_actions permission for this to work.
