2.\[代码\]使用方法

require "database/sqlsrv\_driver.php"; //导入数据库操作类

$\_db = array( //数据库连接信息

'hostname' => 'localhost', //主机地址

'username' => 'sa', //用户名

'password' => '123', //密码

'dbname' => 'test\_db', //数据库名

'port' => 1433, //端口 默认1433

);

$db = SQLSrv::getdatabase($\_db); //数据库连接

\#最终 $db 就是你的数据库实例

\#查询示例

$sql = "select \* from table1";

\#查询单条：

$result = $db->find($sql);

\#查询多条：

$result = $db->findAll($sql);

\#执行增删改：

$result = $db->query($sql);
