예시 애플리케이션(PDO_SQLSRV 드라이버)
AdventureWorks 제품 검토 예시 애플리케이션은 Microsoft Drivers for PHP for SQL Server의 PDO_SQLSRV 드라이버를 사용하는 웹 애플리케이션입니다. 애플리케이션을 사용하면 사용자가 키워드를 입력하고, 선택한 제품에 대한 리뷰를 살펴보며, 선택한 제품에 대한 검토를 작성하고, 선택한 제품에 대한 이미지를 업로드하여 제품을 검색할 수 있습니다.
예시 애플리케이션 실행
- Microsoft Drivers for PHP for SQL Server 설치 자세한 내용은 Microsoft Drivers for PHP for SQL Server 시작을 참조하세요.
- 이 문서의 뒷부분에 나열된 코드를 adventureworks_demo.php 및 photo.php 두 파일에 복사합니다.
- adventureworks_demo.php 및 photo.php 파일을 웹 서버의 루트 디렉터리에 배치합니다.
- 브라우저에서 https://localhost/adventureworks_demo.php를 시작하여 애플리케이션을 실행합니다.
요구 사항
AdventureWorks 제품 검토 예시 애플리케이션을 실행하려면 해당 컴퓨터에 대해 다음 조건을 만족해야 합니다.
- 시스템이 Microsoft Drivers for PHP for SQL Server의 요구 사항을 충족합니다. 자세한 내용은 Microsoft Drivers for PHP for SQL Server에 대한 시스템 요구 사항을 참조하세요.
- adventureworks_demo.php 및 photo.php 파일이 웹 서버의 루트 디렉터리에 있어야 합니다. 파일에는 이 문서의 뒷부분에 나열된 코드가 포함되어야 합니다.
- AdventureWorks2008 데이터베이스가 연결된 SQL Server 2005 또는 SQL Server 2008이 로컬 컴퓨터에 설치됩니다.
