I would like to store value from while loop but not in multidimensional way :
$movies_id = array(); while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) {
Your code would not work in case of PHP version less than 5.4. In that case you can use the following.
$movies_id = array(); while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) { $id = $row['id']; $title_id = $row['title_id']; $movies_id[] = array($id => $title_id); } print_r($movies_id);
