The websites are a little slower to load, but I'm going to move them into the /var/www/html/ folder now while I work on some other stuff.  Eventually they might work in /tmp/html, where they can be accessed in memory of the storage file system.  On disk, they can be accessed now, but that slows down the process.

I want to get that directory script done.  It is not a priority.  I have in mind what I want to do for it.  What it does is copy files into /tmp/html that are uploaded to /var/www/html.  

I can use the DirectoryIterator - or the SplFileInfo object for a file to determine if it is a soft link.  And, if it is, if it has the name index.php, instead of copying it, a new index.php can be linked to /var/www/html/shed/index.php.

The problem might have come from using Tar to extract the files into that directory.  The old symlinks didn't work.  They did work at first - but I ran into a problem.  I had to go onto howeverwhich.com, in the folder, and delete and replace the old symlink.  I used the function: link_global_index, which is a script I typed myself.
