PHP SQL query error

Question

I have some problem with type conversation in this code (working with Facebook PHP SDK 3.0.1):

$page_id = 192485754113829;
$post_limit = 2;

$query = \"select po         


        

Answer 1

$query = "select post_id, source_id, actor_id, target_id, created_time, likes, message, attachment, comments from stream where source_id = '$page_id' LIMIT $post_limit";

or

$query = "select post_id, source_id, actor_id, target_id, created_time, likes, message, attachment, comments from stream where source_id = '".$page_id."' LIMIT ".$post_limit."";

(if page_id is an integer you can write it without any quotes)

the problem is in quotes.
