我已经安装了freetds，我想通过php连接到mssql服务器。我正在使用centos。
root@server [~/php]# tsql -C
Compile-time settings (established with the "configure" script)
Version: freetds v0.91
freetds.conf directory: /usr/local/etc
MS db-lib source compatibility: no
Sybase binary compatibility: no
Thread safety: yes
iconv library: yes
TDS version: 5.0
iODBC: no
unixodbc: yes
SSPI "trusted" logins: no
Kerberos: no
我用来连接mssql服务器的php代码。 （它位于子目录中）我能够通过本地mssql server 2008连接到远程mssql服务器。
<?php
// Older FreeTDS installations need the FREETDSCONF Environment variable
putenv('FREETDSCONF=../usr/local/etc/freetds.conf');
// Current release of FreeTDS uses the FREETDS environment variable. So we set both to be sure
putenv('FREETDS=../usr/local/etc/freetds.conf');
$mssql = mssql_connect('116.214.26.236' , 'dbname', 'password');
//mssql_select_db('myDb',$mssql);
if (!$mssql) {
die('Something went wrong while connecting to MSSQL');
}else echo 'Success';
?>
我的TDS配置文件

我得到的错误
警告：mssql_connect（）[function.mssql-connect]：无法连接到服务器：第6行/home/butter/public_html/investonline/mssql.php中的116.214.26.236连接到MSSQL时出错
请指导我哪里出错了。
我在google搜索过一些博客说下面的行值必须是，MS db-lib源兼容性：没有
我的php.ini conf文件

另外，让我知道如何获取日志，以便我知道哪一步有错误。
另外，为什么我无法连接到mssql服务器。
你可以使用PDO php库连接sql server，你可以像这样使用$ output = new PDO（'mssql：host = SERVERHOST; dbname = DBNAME'，'DBUSERNAME'，'DBPASSWORD'）;
