Some people used to think that was the best way to do it, but that practice was renounced quite some time ago. The official PHP manual pages of interest to you are: [man]install.windows.manual[/man] and [man]install.windows.apache2[/man]. If you follow those instructions, you'll be fine.

It hasn't changed in a very long time, no - it's always been necessary to do that.
Also, can you attach your httpd.conf file (you'll probably have to rename it to have a '.txt' file extension) to your next post?
Finally, how did you install PHP? Did you download the .zip package and extract its entire contents to "C:/php" ?
