>&#13;     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
     <TT
CLASS="filename"
>ntwdblib.dll</TT
> from 
     <TT
CLASS="filename"
>\winnt\system32</TT
> on the server to
     <TT
CLASS="filename"
>\winnt\system32</TT
> on the PHP box.
     Copying <TT
CLASS="filename"
>ntwdblib.dll</TT
> will only provide access.
     Configuration of the client will require installation of all the tools.

>&#13;     Requirements for Unix/Linux platforms.
    </P
><P
>&#13;     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:

>&#13;  The MSSQL extension is enabled by adding extension=php_mssql.dll to
  <TT

>php.ini</TT
>.
 </P
><P
>&#13;  To get these functions to work, you have to compile PHP with
  <TT
CLASS="option"
>--with-mssql[=DIR]</TT

  FreeTDS install prefix.
