Cool man, I will give that a try on a separate offline rig.
You make it sound a lot simpler than all the docs I came across before.
Thanks
EDIT
DUDE!!! THANK YOU SOOOOO MUCH FOR THOSE INSTRUCTIONS!!!!!
I was able to run my PHP stuff with XAMPP when clicking on the html webpages that had the forms, once I had them in that htdocs (and my sub folder in there).
When I had tried the HTML5 pages for my AppGameKit builds, they kept giving me that error. So, I had given up and was doing the upload to test thing.
However, once I followed your instruction in #5 by typing the file path in the browser, rather than opening the page by clicking it, it works fine.
So, I did not have to do another install because the XAMPP works fine now when I type the path in the address bar instead of clicking the html file to open it.
I had been using XAMPP, because it has an installer and was easy to get up and running rather than installing Apache manually.
Of course, I only tested a quick simple build, but the error is gone, and the build is working!
Thank you very much for helping me discover my user error!!!
