Which standalone PHP web server? you can simply installed PHP service/component on IIS or Apache. There's nothing special. Hope that helps.
The QuickPHP web server. I was told it is easy to use but after I have started the QuickPHP web server, when double click a test php program, nothing displayed. Unlike other htm programs, when double click the program, IE will display this web page. I like to konw what else do I need to do beside starting this standalone web server so I could run the php program.
Found out how to use QuickPHP. On the QuickPHP screen, set the root folder to a folder where all the php files are kept. Set the default document filename to any filename you like. Start the web server. To run the default file - type http://127.0.0.1:5723/ in the IE address line. To run other php file - type http://127.0.0.1:5723/filename.php in the IE address line. Tested this on XP professional (PC) and Vista (laptop).
