function fb_api in Drupal for Facebook 7.3

Same name and namespace in other branches

1. 6.3 fb.module \fb_api()
2. 7.4 fb.module \fb_api()

Simple wrapper around $fb->api() which caches data. Does not support the polymorphic arguments of $fb->api(). This is not a replacement for that function.

This is intended to avoid performace problems when, for example, $fb->api('me') is called several times in a single request.

Parameters

$graph_path: Something facebook's graph API will understand. Could be an ID or a path like 'me/accounts', for example.

$params: Extras to pass to the graph API. When making a request that requires a token, try array('access_token' => fb_get_token()).
