Ubuntu 12.04, running on Apache server. I wonder if that is possible to access from browser html/php file from other than document root location let's say from folder /testfolder on the root

So once I enter in browser example.com/testfolder It will be executed the same as from var/www/example.com/httpdocs/testfolder.

But files and this folder will be on the root in /testfolder not in document root (httpdocs) I don't want to put this folder physically at all in httpdocs. Goal is to hide those files/folder from default www vhost folder.

Of course files var/www/example.com/httpdocs/ will be normally there.

In other words I want to run some folder which is not in logic structure of httpdocs but should be treated like it would be there.

Indeed you can, though putting some php files on / may not be the best idea.

Do a search on the term "Apache mod_userdir"
and / or look over here :
