There is one other option called WAMP it turns your pc into a server with php, mysql support. Great for testing and development.
I recommend also wamp, is very good for testing , easy to install change settings, and you can use it only for testing on localhost or put online (to see it from other computers)
down load the wampserver from this site.. http://sourceforge.net/project/down...r&filename=WampServer2.0h.exe&use_mirror=nchc
Dreamweaver is only an WYSIWYG editor for php. It is a great tool for helping us to do many php jobs easily without memorizing a lot of php codes and html codes. But you still have to install XAMP or EasyPHP so that you can have the Web Server, MySql Server and PHP Application Server enabled so that you could run PHP in any editor.
hmm... did you copy all the files into www folder? if you did, did you see .htaccess file? if yes, for me I deleted it and it works fine for me
