";?>

回复讨论(解决方案)

配置php.ini,??php?mssql的?展即可.

PDO drivers mysql, sqlite, sqlsrv ???
只有这个？
你单写一个程序

<?phpvar_dump(function_exists('sqlsrv_connect'));

PDO drivers mysql, sqlite, sqlsrv ???
只有这个？
你单写一个程序

<?phpvar_dump(function_exists('sqlsrv_connect'));

PDO
---------------------------------------
PDO support enabled
PDO drivers mysql, sqlite, sqlsrv

确实只有这几个呀！是不是还要安装啥呢？

配置php.ini,??php?mssql的?展即可.
已经百度了好多下了，发现对5.2以下版本可以用，以上版本的因为sql server数据库版本不同，所以这方法不推荐了。而且我也尝试了下载php_mssql.dll，然后添加注释，不起作用呀

我用的php版本是5.2.6 一直在正常使用中.

不要开玩笑！
单独一句
var_dump(function_exists('sqlsrv_connect'));
这么可能是 HTTP 错误 500.0 - Internal Server Error
至多是 bool(false)

var_dump(function_exists('sqlsrv_connect'));

呵呵，刚才确实是那样的哈！
现在装成5.3啦，又下载了microsoft driver for PHP for sql server，终于不出错http500啦！
就是5.3的ini文件和5.4的差别很大，不但要填键值，还要添加键名称

唉，又浪费俩小时，还是不行呀！找到问题了，但是不知道怎么解决的！
我用的微软的web platform install安装PHP，它会自动安装一个SQL server 2012 native client的软件。只要把它卸载了，PHP就再也无法运行了，即使装了fastcgi也没用。但是装了它以后，我的sql server 2008数据库就肯定是连不起来的。可以加分加到100粉的，请大侠再给看下吧！

引用的DLL文件版本不对

还是版本不兼容的问题....

最后也没解决呀，逼得只能现学asp.net了，要不是需求SQL server，我用mysql轻松就搞定了。
微软太自私了，明显是想让P(拍)H(黄)P(片)的饿死呀！！！

我的可以，PHP Version 5.4.16 链接 sql2008 链接成功
用sqlsrv 3.0 ，2.0的没有试过，方法是
php.ini 加入
extension=php_pdo_sqlsrv_54_nts.dll
extension=php_sqlsrv_54_nts.dll

数据库链接：
$conn= new PDO("sqlsrv:server=127.0.0.1;database=abc","user","123456") or die ("PDO Connection faild.");
