Requirements for WIn32 platforms.
The extension requires the MS SQL Client Tools to
be installed on the system where PHP is installed. The
Client Tools can be installed from the MS SQL Server CD
or by copying ntwdblib.dll
from \winnt\system32 on the
server to \winnt\system32 on
the PHP box. Copying
ntwdblib.dll will only provide access.
Configuration of the client will require installation
of all the tools.
Requirements for Unix/Linux platforms.
To use the MSSQL extension on Unix/Linux, you
first need to build and install the FreeTDS library.
Source code and installation instructions are available
at the FreeTDS home page:
http://www.freetds.org/
The MSSQL extension is enabled by adding
extension=php_mssql.dll to
php.ini.
To get these functions to work, you have to
compile PHP with
--with-mssql[=DIR], where DIR is the FreeTDS
install prefix.
php.ini中的設定會影響這些函數的行為。
