Loop returning unexpected results

Am try to looping through a database result set, the problem is that i know i have only one row of data, yet the loop returns 5 rows This is my method from my model

function get_latest_pheeds() {
     $data = $this->user_keywords($this->ion_auth->user_id);
     $keyword = $data;
     $user_id = $this->ion_auth->user_id;
            foreach($keyword as $key => $word) {

                $q = "SELECT *,COUNT(pheed_comments.comment_id) as comments
                FROM pheeds
                LEFT JOIN pheed_comments ON pheed_comments.P_id=pheeds.pheed_id
                WHERE pheed LIKE '%$word%' OR user_id='$user_id'
                GROUP BY pheeds.pheed_开发者_如何学Pythonid
                ORDER BY datetime DESC";
                $result = $this->db->query($q);
                $rows[] = $result->result();

            }
            return $rows;
    }

What am i doing wroing

This is because your query has an OR where it should probably have an AND - each query always matches the user_id='$user_id'.

This loop is quite inefficient anyway, I think you want to do something more like this:

function get_latest_pheeds() {
    $keywords = $this->user_keywords($this->ion_auth->user_id);
    $q = "SELECT *,COUNT(pheed_comments.comment_id) as comments
          FROM pheeds
          LEFT JOIN pheed_comments ON pheed_comments.P_id=pheeds.pheed_id
          WHERE (pheed LIKE '%".implode("%' OR pheed LIKE '%",$keywords)."%') AND user_id='".$this->ion_auth->user_id."'
          GROUP BY pheeds.pheed_id
          ORDER BY datetime DESC";
    return $this->db->query($q);
}

If you want your results returned as an array like they were previously, you'll need to loop over results and fetch each of them into an array key of another array. I can't do it here because I can't see your db class...

EDIT: Slight fix in the above code...

ANOTHER EDIT: another fix...
