SQL Server数据库与PHP简介** SQL Server数据库是一种关系型数据库管理系统(RDBMS),由微软开发和维护。它以其高性能、可靠性和可扩展性而闻名。PHP是一种广泛使用的服务器端脚本语言,用于创建动态Web应用程序。将PHP与SQL Server数据库结合使用可以构建强大的数据驱动型应用程序。 PHP提供了一系列函数和类,用于连接、查询和操作SQL Server数据库。这些函数和类允许开发人员轻松地与数据库交互,执行各种任务,例如数据检索、更新和删除。 # 2. PHP连接SQL Server数据库 ### 2.1 连接方法 PHP连接SQL Server数据库主要有两种方法:PDO连接和mysqli连接。 #### 2.1.1 PDO连接 PDO(PHP Data Objects)是PHP中用于数据库操作的扩展。它提供了一个统一的接口,可以连接到多种数据库,包括SQL Server。 **代码块:** ```php <?php $dsn = 'sqlsrv:Server=localhost;Database=myDB'; $username = 'myUsername'; $password = 'myPassword'; try { $conn = new PDO($dsn, $username, $password); $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); } catch (PDOException $e) { echo 'Connection failed: ' . $e->getMessage(); } ``` **逻辑分析:** * `$dsn`变量包含了连接到SQL Server数据库所需的信息,包括服务器名称、数据库名称、用户名和密码。 * `PDO`类用于建立与数据库的连接,并指定了连接信息。 * `setAttribute`方法用于设置PDO连接的错误处理模式,将其设置为异常模式,以便在发生错误时抛出异常。 #### 2.1.2 mysqli连接 mysqli是PHP中另一个用于数据库操作的扩展,专门用于连接MySQL数据库。但是,它也可以通过使用`mysqli_connect`函数来连接到SQL Server数据库。 **代码块:** ```php <?php $server = 'localhost'; $username = 'myUsername'; $password = 'myPassword'; $database = 'myDB'; $conn = mysqli_connect($server, $username, $password, $database); if (!$conn) { echo 'Connection failed: ' . mysqli_connect_error(); } ``` **逻辑分析:** * `mysqli_connect`函数用于建立与SQL Server数据库的连接,并指定了连接信息。 * 如果连接失败,则`mysqli_connect_error`函数将返回错误消息。 ### 2.2 连接参数配置 在连接到SQL Server数据库时,可以通过指定连接参数来配置连接行为。这些参数包括: **表格:** | 参数 | 描述 | |---|---| | **Server** | SQL Server服务器的名称或IP地址 | | **Database** | 要连接的数据库的名称 | | **Uid** | 连接到数据库的用户名 | | **Pwd** | 连接到数据库的密码 | | **CharacterSet** | 连接使用的字符集 | | **ApplicationIntent** | 指定连接的应用程序类型 | | **MultipleActiveResultSets** | 允许在单个连接上执行多个并发查询 | **代码块:** ```php <?php $server = 'localhost'; $database = 'myDB'; $username = 'myUsername'; $password = 'myPassword'; $charset = 'UTF-8'; $applicationIntent = 'ReadOnly'; $multipleActiveResultSets = true; $conn = mysqli_connect($server, $username, $password, $database); if (!$conn) { echo 'Connection failed: ' . mysqli_connect_error(); } mysqli_set_charset($conn, $charset); mysqli_options($conn, MYSQLI_OPT_APPLICATION_INTENT, $applicationIntent); mysqli_options( ```
