Wow, amazing! Thank you so much Josh! I so very much appreciate the help!
I have one last question in regards to your last comment: "This is common in for instance shared hosting environments, where multiple people share the same server." I guess I am a little bit worried about this, as in my experience, a lot of servers do share. So I was hoping to create a place where I could set a variable referring to "my root". I would like to do this, so if all of a sudden, when I move this to the actual server, or a different server, I could just set the "root" in one place, instead of having to go through all my code and look for the "$_SERVER['DOCUMENT_ROOT'].'/" and make the adjustment in many places.
I was hoping there was something I could set in one place, like so:
$my_root = $_SERVER['DOCUMENT_ROOT'] . '/somedirectory/';
Then I could use $my_root the rest of the time, instead of $_SERVER['DOCUMENT_ROOT']. But not sure if that is possible and not sure where that would reside? Maybe this is a pipe dream...
