windows下非常简单,而linux下则难一点。说清楚大家才好帮你。
应该如何解决谢谢各位。

1、找个sql server的客户端,安装。
2、然后先用企业管理器配置好和server的连接。
3、修改你的php.ini,以下是修改步骤。
*************************************************************
a.设置你的extension_dir,比如我的:extension_dir = c:\php\extensionsb.加载相应的dll
把windows extensions下的
;extension=php_mssql.dll前的分号去掉。c.重新启动你的web服务器。
d.象楼上的老兄说的一样,使用phplib提供的数据库连接类,那会更容易使用,而且以后移植数据库也会比较轻松。
*************************************************************good luck~~~~
