I have a file called t.php:
<html>
<body>
<?php
require "http://localhost/~derek/l.php";
rp(3);
?>
</body>
</html>
and l.php:
<?php
echo "define function...";
function rp( $num )
{
echo "rp: $num";
}
echo "defined";
?>
When I load t.php into my browser it prints "define function...defined
Fatal error: Call to undefined function: rp()
in /home/derek/public_html/t.php on line 6"
So, I know the library code is being loaded and executed (because the
strings are echoed) but rp() isn't being defined. Experimentation shows
it's not just functions which I'm not getting defined, as I get the same
sort of error if I just define a variable and try to get it printed in
t.php.
Can someone tell me what I'm doing wrong? I'm using PHP-4.3.4 on SUSE
LINUX-9.1.

Actually, Your webserver is executing the php-file (and thus outputs
the lines) but you're receiveing only the executed outcome, not the
php-file itself.
So essentially, what you get from http://localhost/~derek/l.php is the
following:
define function...defined
and not what you're expecting. Hope I'm making sense here :)

You are not including the source code of l.php but the result of it being
run on the server, which is just the string "define function...defined",
which in turn is interpreted as HTML and displayed by t.php. You must either
include the file locally (e.g. require "/home/derek/l.php";) or make the
server not interpret the file (e.g. by giving it another extension like
".inc" or ".txt").

Ah, right. Thanks. But just to clarify, if I rename it to something other
than .php, and someone learns the pathname to the file, they can ask my
webserver for the file directly and they'll get to see my source code -
right?

Yes, for which very reason you'll probably want to want to use a more
appropriate technology such as SOAP http://www.php.net/manual/en/ref.soap.php

yup but if you place the files that you are wanting to display in this
manner in a folder that is outside of the web-root server such as
/var/www/txt/foo.bar
instead of in
/var/www/html/foo.bar
where /var/www/html/ is the web-root directory
then the files in the txt/ folder are not accessible directly to
browsers and php files can load them by using ../txt/foo.bar
this is a fairly basic principle of site design/management i think... :/

Hey,
While JV is right, that would only work if the files you include reside
on the same server as your script (assuming your script would have
access to the files).
Otherwise, as I imagine you want, to execute remotely hosted functions
and in the same time conseal the source, CJ Llewellyn is right that you
should either use a technology like SOAP or just design a simple
interface to your PHP functions (latter being, to my preference, the
worse approach, because you can just use something standartized).
