Dreamweaver - PHP and MySQL "Undefined Error"

I'm trying to connect to MySQL db from Dreamweaver and after 2 days, I'm starting to loose my pacient. Macromedia blames PHP for any "unexplain" reason why their software might not connect to MySQL. I tried everything they said on their support page and still no result. Anyone in here uses Dreamweaver to write PHP with a mySQL backend? Something I found is that php.ini when installed in Windows comments the include_path lines, lines that supposely, Dreamweaver needs to access MySQL when using PHP to connect. The error message I get from Dreamweaver when I leave the comments on the include_path lines in the php.ini file is: "Undefined Error" and when I remove the comments I get: "Error parsing C:\WINDOWS\php.ini on line 435" which is the line that had the comments. Help! anyone that have successfully connected to MySQL with via Dreamweaver. I have upgrade my Mysql to 5 Beta, and php to 5 also trying to see if that would fix the problem but with no result. Many thanks, Jay - Florida
