[EMAIL PROTECTED] you are an arrogant bastard aren't you?
If six people over 16 months have had to debate what an oversimplified
paragraph means, don't you think that "pretty clear" might not be an
appropriate way to describe said oversimplified paragraph?
Just because it's clear to you, doesn't make it clear. In my case, the
only clear explanation I've seen is that from elmicha#phpdotnet earlier
in this thread.
Tim and kenny have both seen that there's missing clarity with respect
to remote servers, and tried to understand and explain the implications
of your "perfectly clear" paragraph.
But those who have been concerned with trying to make themselves feel
smart (like you), or with trying to make me feel stupid for asking
(like brianlmoon), rather than actually thinking about the problem,
simply make me sad for the entire group of geeks to which I once
belonged. I hope you're all replaced by low-paid Indian and Chinese
programmers and have to flip "pretty clear" hamburgers for a living.
Have I been "pretty clear"? Call me, you supercilious geek, and I'll
happily tell you off in person.

I believe the include() documentation is pretty clear on this issue:
"The include() statement includes and evaluates the specified file."
"When a file is included, the code it contains inherits the variable
scope of the line on which the include occurs. Any variables available
at that line in the calling file will be available within the called
file, from that point forward."
Status -> Closed.

elmicha below has answered my question perfectly well and explained the
results I got too.
To my mind, this docbug should be considered closed when elmicha's
explanation is included in the docs for include().
Thanks to all who replied,

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.
