PHP连接MSSQL数据库错误 急急急急
我用mysql_connect()连接MySql数据库正常，但是用mssql_connect()连接不上，提示不能连接到数据库。用PDO连接同样连接不上。之前我用C++做的一个程序连接我的SQL SERVER一切正常，请问是什么原因呢，求解释啊，急急急
我把我的PDO连接和错误代码都挂上，方便高手解答，万分感谢
$dbh = new PDO('mssql:host=localhost;dbname=MyData','sa','*****');//密码已隐藏
就这一句代码，连接不上，错误提示是：
'SQLSTATE[01002] Unable to connect: SQL Server is unavailable or does not exist. Access denied. (severity 9)'
