偵測是否要取得最新版本的 Flash 檔案

Flash loader 在開始取得檔案前, 先用 xxx?v=28172364656 的方式取得一個設定檔, 該設定檔帶的 v={microtime} 其時間單位為 load 檔時的時間郵戳, 以確保該設定檔每次都是 load 到最新的, 再將要取得的檔案列表放在該設定檔內, 每個檔案都用 yyy?v=123458 的方式做版本控制, 這樣應該可以讓 Flash loader 隨時都能取得最新的檔案

$query->useResultCache(true, 3600, 'allItems');
$items = $query->getArrayResult();

// delete cache
$em->getConfiguration()
   ->getResultCacheImpl()->delete('allItems');
