码：

new \PDO("dblib:host={$hostname};dbname={$dbname}",$user,$pass);

抛出：

sqlSTATE[01002] Adaptive Server connection Failed (severity 9)

但是CLI的连接工作正常

tsql -S主机名-U user -P pass -L dbname：

locale is "cs_CZ.UTF-8"
locale charset is "UTF-8"
using default charset "UTF-8"

freetds.conf：

[hostname]
    host = ipaddress
    port = 1433
    tds version = 8.0

tsql -C：

Version: freetds v0.91
         freetds.conf directory: /usr/local/Cellar/freetds/0.91/etc
 MS db-lib source compatibility: no
    Sybase binary compatibility: no
                  Thread safety: yes
                  iconv library: yes
                    TDS version: 7.1
                          iODBC: no
                       unixodbc: no
          SSPI "trusted" logins: no
                       Kerberos: no

有任何想法吗？我尝试过最好的东西,连接到hostname,ip,有和没有端口,到实例名称,另一个用户,TDS版本7.0,7.1,7.2,8.0,重新安装PHP和freetds
