When using WAMP...if you want to view your website (In the C:\WAMP\WWW Dir.), you "should" be able to use http://localhost/DaysArray.php. However, with IE8, I couldn't get my PHP to execute, probably because of security settings on INTRANET type sites. I found that I was able to execute the PHP with Google Chrome. Of course, I wanted to get it to work with IE8, so I found that if you put your IP address: http://MYIPADDRESS/DaysArray.php instead of "localhost", it works. MYIPADDRESS should be, for example: 111.111.111.111, and can be found by typing "cmd" in the run box, and "ipconfig"...
This may be obvious to most of you, but thought I might be able to help someone.
