$_SERVER['DOCUMENT_ROOT'] contained. That would have negated pretty much
all the rest of the test code, etc, that you wrote, as that's the actual
Do you mean to for example do some kind of dir listing based on

If so I have no idea how to do that...
I assume that there is a PHP command to help but I have not been using such ever
so I don't know.

No, $_SERVER['DOCUMENT_ROOT'] is a string, just echo out what it
actually is on both versions of PHP. That would show you what you now
know, that it's different for whatever reason. It could be a script

In the code I am struggling with it uses double quotes rather than single quotes
as you show here,

The only difference between single and double quote is how PHP handles string interpolation, e.g.:

echo "this is $var";
echo 'this is $var';

Will give you the output:

this is something
this is $var
