我正在尝试使用 php5-mssql 设置用于 php 开发的 Ubuntu 工作站。首先，我编译了 freetds-nightly 0.8.3（使用 --enable-msdblib ）并将其安装到 /usr/local/freetds ，将包中的头文件复制到 /usr/local/freetds/include
然后，我使用 apt-get source php5 获取 php5 源，并编译 mssql 扩展，如下所示：
phpize
cd ext/mssql
./configure --with-mssql=/usr/local/freetds
make
sudo install
这会将 mssql.so 放入我的 php 扩展目录中，php 可以正常加载扩展。完成所有这些后，我在 /usr/local/freetds/etc/freetds.conf 中添加了我的服务器：
[global]
tds version = 7.0
dump file = /tmp/freetds.log
text size = 64512
[db-02]
host = XXXXX
port = 1433
tds version = 7.0
首先，我想使用 tds 8.0，但任何高于 7.1 的值都会被忽略，这很奇怪，因为我的 mac 上的 freetds（由 macports 使用 +mssql 构建）使用的是 8.0，但版本较旧。（我认为是 0.8.2）
无论如何，通过这个，我可以通过 /usr/local/freetds/bin/tsql 顺利连接到我的服务器。而不是使用 php5-mssql。
这是 freetds.log 的一些输出（这都是失败的尝试的结果）

（我可以使用相同的凭据通过 tsql 进入）
任何帮助是极大的赞赏。
谢谢，安德鲁
ps: 一些 tsql -C 输出

解决了。应该使用稳定版本。0.8.2 支持 tds 8.0，0.8.3 不支持。呃。
顺便说一句，这仍然不能解释为什么我能够使用协议 7.1 通过 tsql 连接到我的 mssql 服务器，但不能使用 php5-mssql。
