Örnek Uygulama (PDO_SQLSRV Sürücüsü)

PHP sürücüsünü indirme

AdventureWorks Ürün İncelemeleri örnek uygulaması, SQL Server için PHP için Microsoft Sürücüleri'nin PDO_SQLSRV sürücüsünü kullanan bir Web uygulamasıdır. Uygulama, bir kullanıcının anahtar sözcük girerek ürün aramasına, seçili ürün için incelemelere bakın, seçili ürün için gözden geçirme yazmasına ve seçili ürün için görüntü yüklemesine olanak tanır.

Örnek Uygulamayı Çalıştırma

  1. SQL Server için PHP için Microsoft Sürücüleri'ni yükleyin. Ayrıntılı bilgi için bkz. SQL Server için PHP için Microsoft Sürücüleri ile Çalışmaya Başlama
  2. Bu belgede daha sonra listelenen kodu iki dosyaya kopyalayın: adventureworks_demo.php ve photo.php.
  3. adventureworks_demo.php ve photo.php dosyalarını Web sunucunuzun kök dizinine yerleştirin.
  4. Tarayıcınızdan başlayarak https://localhost/adventureworks_demo.php uygulamayı çalıştırın.

Gereksinimler

AdventureWorks Ürün İncelemeleri örnek uygulamasını çalıştırmak için aşağıdakiler bilgisayarınız için doğru olmalıdır:

AdventureWorks örneği

AdventureWorks Ürün İncelemeleri örnek uygulaması aşağıdakileri gösterir:

  • Windows Kimlik Doğrulaması kullanarak SQL Server bağlantısı açma.
  • Parametreli sorgu hazırlama ve yürütme.
  • Verileri nasıl alacağınız.
  • Hataları nasıl kontrol edeceğiniz.

Bu örnek, adları kullanıcı tarafından girilen bir dize içeren ürünler için veritabanından ürün bilgilerini döndürür. Döndürülen ürünler listesinden kullanıcı incelemeleri görebilir, görüntü görebilir, görüntü yükleyebilir ve seçili bir ürün için gözden geçirme yazabilir.

Aşağıdaki kodu adventureworks_demo_pdo.php adlı bir dosyaya yerleştirin:
