How to get the stream of a public Facebook fanpage in php?

Question

Hi,

I want to display my public fanpage feed onto my website via the Facebook API without requiring a login.

I'm doing this

require_once('../includes/classes/facebook-platform/php/facebook.php');

$fb = new Facebook($api_key, $secret);
$fb->api_client->stream_get('',$app_id,'0','0','','','','',''));

But I get this error

 Fatal error:  Uncaught exception 'FacebookRestClientException' with message 'user id parameter or session key required' in includes/classes/facebook-platform/php/facebookapi_php5_restlib.php:3065
 Stack trace:
#0 includes/classes/facebook-platform/php/facebookapi_php5_restlib.php(1915): FacebookRestClient->call_method('facebook.stream...', Array)
#1 facebook/api.php(12): FacebookRestClient->stream_get('', 13156929019, '0', '0', 30, '', '', '', '')
#2 {main}
  thrown in includes/classes/facebook-platform/php/facebookapi_php5_restlib.php on line 3065

Then I figured, because of 'user id parameter or session key required', to add my user id to the call

require_once('../includes/classes/facebook-platform/php/facebook.php');

$fb = new Facebook($api_key, $secret);
$fb->api_client->stream_get(502945616,13156929019,$app_id,'0','0','','','','',''));

But then I got this error

Fatal error:  Uncaught exception 'FacebookRestClientException' with message 'Session key invalid or no longer valid'

I'm totally clueless :)

Answer 1

Here's what i did

1) Login to facebook.

2) Grant your application offline access to your account: http://m.facebook.com/authorize.php?api_key=YOUR_API_KEY&v=1.0&ext_perm=offline_access

3) Add read stream permission http://m.facebook.com/authorize.php?api_key=YOUR_API_KEY&v=1.0&ext_perm=read_stream

4) Generate a key code http://www.facebook.com/code_gen.php?v=1.0&api_key=YOUR_API_KEY

5) Run this script once and copy the "session_key".

$facebook = new Facebook($api_key, $api_secret);
$infinite_key = $facebook->api_client->auth_getSession(YOUR_KEY_CODE);
print_r($infinite_key);

6) Plug and play!

$facebook->api_client->user = YOUR_FACEBOOK_USER_ID
$facebook->api_client->session_key = YOUR_INFINITE_KEY
$facebook->api_client->expires = 0;
$feed = $facebook->api_client->stream_get(YOUR_FACEBOOK_USER_ID, FAN_PAGE_ID);

So bascially, this will grab the feed from your "perspective" but filter it only to show items from the specified Fan page.

Disclaimer: This works, but I'm not sure whether this is a "supported" method for grabbing data, or even allowed at all.
