Requirements
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
through named pipes.
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:

Note:
In Windows, the DBLIB from Microsoft is used. Functions that return a
column name are based on the dbcolname() function
in DBLIB. DBLIB was developed for SQL Server 6.x where the max
identifier length is 30. For this reason, the maximum column length
is 30 characters. On platforms where FreeTDS is used (Linux), this is
not a problem.
