I've been trying to get this to work myself. Found the solution. $facebook->api() is going to return a json array. This is not a valid element for a foreach() statement. You need to use json_decode($statuses) in order to loop through the array in the foreach() statement.

Foreach through JSONArray in PHP

That error message generally happens when your array variable is not set. If you could add line numbers to your code and give the full error message (including line number) it might help.

Can you show a print_r of $statuses['data']?
