调用方法

$dbss['hostname']='localhost';
$dbss['username']='sa';
$dbss['password']='111111';
$dbss['dbname']='text';$msdb=new SQLSrv($dbss);
//查询
$query=$msdb->query("select * from table");
while($rs=$msdb->fetch_array($query)){print_r($rs);
}
//增 删除 改
$msdb->query("delete from table");
$msdb->query("update table set xxx='123' where id='1'");
$msdb->query("INSERT INTO table ([id], [title]) VALUES ('1', '年休假1')");//注意查询处理的中文默认是gbk编码 需要转化
//写入数据库时也需要转成gbk
