Query in a loop how to get result array in Codeigniter

i am trying to fetch result of a query that is in a loop but i cant get all the records returned by query that is in the loop please guide me.

  $qry = '';
    $qry = "SELECT    
            `user_id`  FROM 
            `view_property_user_lab`";
    $qry .= " WHERE property_id = '" . $propId . "'";
    $result = $this->db->query($qry);
    $result_count = $result->result_array();
    foreach ($result_count as $row)
    {
        $user_name_qry = "SELECT
                                 `name`
                                    FROM USER
                                    WHERE user_id =  '" . $row['user_id'] . "'";
                                   $user_name_result = $this->db->query($user_name_qry);
    }

    $result_count_user = $user_name_result->result_array();
    print_r($result_count_user);

This is the dump of array 

 Array ( [0] => Array ( [name] => abc) )

I think your problem is that you're using a foreach loop, but everytime you overwrite the same variable ($user_name_result) and you use only the last one assigned to get the data from the result resource (since you're calling that outside the loop!).

But all in all, as tersko said in the comments, doing queries in loops isn't a good thing (hitting your db the more your users increase).

You can simplify everything with a JOINed query (just guessing your table schema here, though):

$sql = "SELECT u.name FROM view_property_user_lab AS v JOIN user AS u ON u.user_id = v.user_id WHERE v.property_id = ?";
$query = $this->db->query($sql,array($propID));

print_r($query->result_array());
