Is the curl code written correctly in the parsing loop?

Question

PHP

Is the curl code written correctly in the parsing loop? initialization $cn = curl_init(); put in a loop?

if($act == 'go'){
    
    $sql = $db->query("SELECT `game_id`, `game_prlink1` FROM $db_games WHERE game_prstatus<2 AND game_prlink1 IS NOT NULL AND game_prlink1 <> ''");
    $ar_link = $sql->fetchAll(); //берем id и ссылки в массив
    //$par_ok = print_r($ar_link); 
    
    $referer = 'http://www.google.com';
    // 1. инициализация
    $cn = curl_init();
    // 2. устанавливаем опции включая урл в цикле
    foreach ($ar_link as $row){		
      curl_setopt($cn, CURLOPT_URL, $row["game_prlink1"]);
      curl_setopt($cn, CURLOPT_HEADER, 0);
      curl_setopt($cn, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows NT 6.1; WOW64; ry:38.0) Gecko/20100101 Firefox/38.0");
      curl_setopt($cn, CURLOPT_REFERER, $referer);
      curl_setopt($cn, CURLOPT_RETURNTRANSFER, true);
      
      // 3. выполнение запроса и получение ответа
      $data = curl_exec($cn);
      
      //4. чистим html
      $res2 = cot_keybox_parse($data, '<div class="bottom_line clearfix">', '<sup>');
      $trimmed = trim($res2);
      
      //5. запись в базу
      $db->update($db_games, array('game_prstatus' => '1', 'game_prprice1' => $trimmed), "game_id = ".$row['game_id']."");	
    }
    // 6. закрываем
    curl_close($cn);
  }
