How to get array values in codeigniter using explode method

Question

Query run is based on 2 id, however I get one output value

Input:

public function get_place_order_category($id)
  {
     /* $id = 1,2;*/

      $ids = explode(',',$id);
      foreach($ids as $catid)
      {
      $this->db->where('product_id =',trim($catid));
      $query = $this->db->get('products'); 

      return $query->result_array();          
      }

  }

Output:

Array
(
    [0] => Array
        (
            [product_id] => 12
            [product_name] => Product1
            [product_code] => pro12345

You can use one global array and add result arrays to it. Try this:

public function get_place_order_category($id)
  {
     /* $id = 1,2;*/
     //first test here what comes in $id
      echo $id."<br/>";
      $ans_arr = array();
      $ids = explode(',',$id);
      /*test here too whats actually happens after explode weather   
      arrayhas generated and what are the element of it */
      echo "<pre>";print_r($ids);echo "<br/>";
      foreach($ids as $catid)
      {
          $this->db->where('product_id =',trim($catid));
          $query = $this->db->get('products'); 

          $ans_arr[] = $query->result_array();          
      }
      return $ans_arr;
  }
