This is a long shot, but the Dreamweaver "developing server-side applications" forum directed me to this forum for possible insight into this discussion post:
"I have successfully installed an Apache server and MySQL using Xampp. Using Dream Weaver (CS5.5) I've created .php pages which (after setting up the site and testing server) successfully connect to a database. However, php code on those pages won't execute. The pages only display the text code when IE or Firefox links to http://localhost/filename.php. Following is the Apache log file entries for those failed attempts. [Tue Jul 17 08:20:03 2012] [notice] Child 2656: Starting thread to listen on port 443.

Anyone?"
In my reply to my own above post I added the information that the phpinfo() link in the xampp control panel generates the expected php information table, so it seems implicit that PHP is running in the context of xampp.
Why it won't run in the Dreamweaver environment I don't have a clue, and I'm hoping someone attending to this forum might.
