fetching and looping the fb newsfeed .graph api

fetching and looping the fb newsfeed .graph api

I want to design a news feed with fully functioning likes/Unlike ,share
and commenting,and of course fetching recent posts from users newfeed.Now
here is the thing,I want to check whether a user has liked a post (type is
video, photo, link or status).If a user has liked the post already, then
show unlike button, if a user has not liked, show like button.
FILES:
test.php
THE PROBLEM IS that whenever i remove the following code(Which gets the
user_likes for checking if user has liked the post or not)from the file:
$fql = 'SELECT like_info FROM stream WHERE post_id =' . "$ids";
$ret = $facebook->api(array(
'method' => 'fql.query',
'query' => $fql,
));
$checklike = $ret['data']['like_info']['user_likes'];
the program will fetch only one post from newsfeed or sometimes not at
all.Basically ,Any api calls i make inside the loop(except one for
comment),it will affect the fetching data from newfeed.IS THERE ANY
PROBLEM WITH LOOP OR SOMETHING ,PLEASE HELP AS SOON AS YOU,I APPRECIATE IT
