New Comment:
It really doesn't imply anywhere that including a remote file will make
it inherit the scope -- in fact, it says that is not the case -- and
the 'include' documentation explains that the data returned will be
parsed as is any included file. That is, if the page were "<?php echo
'<?php $foo = \'bar\';'; ?>", the calling script would execute that
assignment in its local scope. If you'd write a better explanation,
I'll be happy to commit it. But since you probably don't care
anymore... :-)

If you use
include('http://some_server/something.php');
something.php is executed on "some_server". It's impossible to return
strings with "return" from there.
But the output of http://some_server/something.php is included in your
script and executed there. So just make _the output_ of something.php a
valid php script which sets your variables - so you can use these
variables in your local script. E.g.:
<?php // something.php on the remote server
echo '<?php $return_value = "a string"; ?>';
?>
On the local server:
<?php
include('http://some_server/something.php');
echo $return_value;
?>
As the manual explicitly mentions that you can use a return statement
to pass values from the included script, but does not mention that this
doesn't work via HTTP or FTP, I'd say this is a Documentation problem.
(I don't know what the manual said in 2001, maybe the return statement
could not be used in included files back then.)

Allow me to rephrase Steve's problem described in #14165 again as I'm
experiencing the same trouble.
When including a remote php-file (a php-file on another server) in a
script, that php-file is parsed (if server configured to) which
basically means the script is runned.
The problem we experience is that the parsed script's return value(s)
defined at the end in a return() statement don't seem to arrive in the
original script. Steve reports only 'integers'. I have seen only a '1',
which is according the docs just the value returned if no return()
statement is used.
If the 2 scripts are located on the same server, the problem doesn't
show up.

Okay, there's some simple sample code at bug 14164.
Basic idea is that I have 2 machines, one public,
one firewalled and non-routed. The public one should
be able to access the database on the private one, but
nobody else should.
Thanks for the attention!
Steve

Maybe if you added some example script here (which you think
should work) we might understand what you mean?
And note that include/require don't return anything.
They are language constructs, not functions.

Dear Brian, Marco et al:
Sorry to be persistent, but I am pretty sure that
my postings have been misunderstood, and the last
reply I just got from Marco confirms it.
I'm hoping once you understand the question, the
"bogus" nature of the question will go away.
According to the php "include()" manual, and
in my own experience, it is perfectly valid to
request that a remote file be executed as php,
using include() or require(). One need only
compile using "URL fopen wrappers": (manual quotes in [[[ ]]])
[[[If "URL fopen wrappers" are enabled in PHP (which they are in the
default configuration), you can specify the file to be include() ed
using an URL instead of a local pathname. See Remote files and fopen()
for more information.
]]]
It is also possible to pass variables to the include()ed
file:
[[[ If the require() ed file is called via HTTP using the fopen
wrappers, and if the target server interprets the target file as PHP
code, variables may be passed to the require() ed file using an URL
request string as used with HTTP GET. This is not strictly speaking the
same thing as require() ing the file and having it inherit the parent
file's variable scope; the script is actually being run on the remote
server and the result is then being included into the local script.
]]]
SO:
The missing feature/doc is:
How do I get the require()ed file to pass back some string
information?
I can't use the HTTP GET-style request string, or even the return()
function
within an include() (because it only returns an integer).
I don't think this is a bogus request, it seems to me to be a logical
extension of the URL request idea. If it's currently impossible, I'm
looking for a workaround.
Marco's suggestion to print out the database using cvs doesn't change
anything, since I still can't pass a string back.
Best regards,
Steve Rapaport.
