範例應用程式 (SQLSRV 驅動程式)

下載 PHP 驅動程式

AdventureWorks Product Reviews 範例應用程式是一種 Web 應用程式,其使用 Microsoft Drivers for PHP for SQL Server 的 SQLSRV 驅動程式。 此應用程式可讓使用者經由輸入關鍵字來搜尋產品、查看所選產品的評論、撰寫所選產品的評論,以及上傳所選產品的影像。

執行範例應用程式

  1. 安裝 Microsoft Drivers for PHP for SQL Server。 如需詳細資訊,請參閱 < 開始使用 Microsoft Drivers for PHP for SQL Server
  2. 將本文件稍後所列的程式碼複製到兩個檔案中:adventureworks_demo.php 和 photo.php。
  3. 將 adventureworks_demo.php 和 photo.php 檔案放入您的 Web 伺服器的根目錄中。
  4. 從您的瀏覽器啟動 https://localhost/adventureworks_demo.php 來執行應用程式。

需求

若要執行 AdventureWorks Product Reviews 範例應用程式,您的電腦的下列項目必須相符:

  • 您的系統必須符合 Microsoft Drivers for PHP for SQL Server 的需求。 如需詳細資訊,請參閱 Microsoft Drivers for PHP for SQL Server 的系統需求
  • adventureworks_demo.php 和 photo.php 檔案位於您的 Web 伺服器的根目錄中。 這些檔案必須包含本文件稍後所列的程式碼。
  • 本機電腦上已安裝 SQL Server 2005 或 SQL Server 2008,並附加 AdventureWorks2008 資料庫。
  • 已安裝網頁瀏覽器。

AdventureWorks 範例

AdventureWorks Product Reviews 範例應用程式會示範下列工作:

此範例會針對其名稱包含使用者輸入字串的產品,從資料庫傳回產品資訊。 在傳回的產品清單中,使用者可以查看評論、查看影像、上傳影像,以及撰寫所選產品的評論。
