Relative URLs and all that mishmash...

Hello all,

I'm having a hard time dealing with relative paths in PHP. Say I have
a directory structure that looks like:

+HOME
|
|---+SUBDIR
|
|---+IMAGES

In the HOME directory, I have a PHP script, "logo.php", which
includes:

foreach(glob("images/*.jpg") as $filename) {
        $files[] = $filename;
}

Then it goes on to pick a random .jpg file from the array for display
on a web page. This works fine.

Now, say I have a script "subdir.php" in the SUBDIR directory which
includes logo.php:

include("../logo.php");

When this subdir.php script gets past the foreach loop, I get the
following error:

Warning: array_rand(): First argument has to be an array in
C:\xampp\htdocs\new\logo.php on line 12

This tells me that the $files array is empty, and it has something to
do with subdir.php being in the SUBDIR directory rather than HOME.

Am I doing something wrong? What can I do to get logo.php to work
properly regardless of where it's being called from?

Thanks for any suggestions,
Joseph
