while($row=sqlsrv_fetch_array($query)),该怎么解决

$serverName = "localhost"; //数据库服务器地址

$uid = "sa"; //数据库用户名

$pwd = "66"; //数据库密码

$connectionInfo = array("UID"=>$uid, "PWD"=>$pwd, "Database"=>"test");

$conn = sqlsrv_connect( $serverName, $connectionInfo);

if( $conn == false)

{
     echo "连接失败！";

    die( print_r( sqlsrv_errors(), true));
}
else
{
	echo "连接成功";
//执行有结果集的SQL语句

	$query = sqlsrv_query($conn, "select ID,NAME from stuff");

	while($row = sqlsrv_fetch_array($query))
	{
　　　　echo $row[0]."-----".$row[1]."
";

	}
	sqlsrv_close( $conn);

}
