Note: this is the email I got when the files were contributed. I cannot test
the code, since I don't have access to mssql, so ymmv. The files referenced
here are at:

lib/mssql.php
admin/translate_mysql.pl (you probably won't need this)

The code for lib/config.php has already been added.

Subject: PHPWiki with Microsoft SQL-Server

My colleague John Clayton set up PHPWiki for our development team using
Apache and MySQL on Windows NT 4.  He then left, and I was asked to port
this to IIS and SQLServer. Please note this is not a reflection of the
Apache and MySQL products, which were performing the task admirably, but had
more to do with consistency of our environment. Since PHP does work with
SQL-Server, the whole migration took about a day. Here are the steps I
carried out:

1. Wrote a sql-server library called mssql.php to reside in wiki\lib.
 <<mssql.php>> 
2. Added the following clause to wiki\lib\config.php
   // MS SQLServer settings
   } elseif ($WhichDatabase == 'mssql') {
      $WikiPageStore = "wiki";
      $ArchivePageStore = "archive";
      $WikiLinksStore = "wikilinks";
      $WikiScoreStore = "wikiscore";
      $HitCountStore = "hitcount";
      $mssql_server = 'servername';
      $mssql_user = 'wikiweb';
      $mssql_pwd = 'wikiweb';
      $mssql_db = 'wiki';
      include "lib/mssql.php";
}

3. Set $WhichDatabase='mssql' in config.php

4. Dumped out the mysql wiki database (mysqldump --user=john
--host=localhost wiki) and wrote the following perl script to convert to
sql-server compatible sql
 <<translate_mysql.pl>> 

5. Loaded the translated db script into SQL-Server and granted relevant
permissions/logins etc. 

6. Set "magic_quotes_sybase=On" in php.ini to handle embedded quote
characters in strings. This is because SQL-Server, like Sybase, uses ''
instead of \' within strings to cope with embedded quotes.

We had some problems initially with the PHP extension dll for sql-server,
but I installed a newer version from http://www.mm4.de. In fact I unpacked
their whole php4.0.5-rc1 distribution.

I make no claims about all this working 100%, but our existing site seems to
work okay in its new IIS/SQL-Server home :-)
