範例應用程式 (PDO_SQLSRV 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 PDO_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
- 安裝 Microsoft Drivers for PHP for SQL Server。 如需詳細資訊，請參閱SQL驅動程序的PHP驅動程序入門
- 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。
- 將 adventureworks_demo.php 和 photo.php 檔案放入您的 Web 伺服器的根目錄中。
- 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：
- 如何使用 Windows 驗證開啟 SQL Server 連接。
- 如何準備及執行參數化查詢。
- 如何擷取資料。
- 如何檢查錯誤。
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。
將下列程式碼放入名為 adventureworks_demo_pdo.php 的檔案中：
