Answer 1

Could you try to add 'type' => 'link' and see if it works? As far as I've read on Facebook forums this is actually a bug.

Answer 2

you are not doing anything wrong, there is a small php mistake in your code due to which your $user_id variable is not being read.
solution,replace single quote with double quote around /$user_id/feed in your code. try this it will work:
$facebook->api("/$user_id/feed",'POST',
array( 'access_token' => $facebook->getAccessToken(),
'message' => 'Hello World!',
'link' => 'www.example.com'
)
);
