require_once() driving me MAD ! - please HELP

I have written a number of PHP include files. I have carefully
partitioned them into logical folders - based on functionality. My
directory structure looks something like this:

$(rootdir)/includes/
$(rootdir)/includes/patterns
$(rootdir)/includes/core/db
$(rootdir)/includes/core/utils
$(rootdir)/includes/core/logger
....

etc.

Each folder contains one or more files. I wrote the following script to
test my db classes:

<?php
echo "In script\n" ;
include ("/db/mysql_database.inc.php");
echo "Got here\n" ;

try
{
echo "Attempting to instantiate db object\n" ;
$m_dbconnection = new MySQLDatabase();
echo "Object created succesfully\n" ;
}
catch (Exception $e)
{
echo "Exception caught : " . $e->getMessage() . "\n" ;
}
?>

Output: "In script Got here Attempting to instantiate db object "

I cannot, for the life of me, work out wtf is wrong iwth the script, and
why I can't seem to use my directory structure. The above script is
being run from $(rootdir). $(rootdir) is in folder htdocs under Apache.

Additional Info:

PHP Version: PHP5
Web Server: Apache 2.0

include ("/db/mysql_database.inc.php");

This would be an absolute path to the file system, not a relative path
in your web server. If you were displaying errors you would have one
indicating the file was not found.

Hi Jerry, not sure I follow your response (i.e. its rather ambigious).
Did you mean to say that my include directive SHOULD (you wrote WOULD)
be an absolute path to the file system ?.

To avoid going round in circles over the syntax of should and would,
could you please correct the include statement - so that the new line is
the correct statement that will work.

For example, should I write:

include ("c:\my_full_path\db\mysql_database.inc.php"); //note windows
path notation OR
include ("c:/my_full_path/db/mysql_database.inc.php"); OR
include
("../path_relative_from_THIS_file_to_include_file/db/mysql_database.inc.php");
OR
include
("..\path_relative_from_THIS_file_to_include_file\ db\mysql_database.inc.php")

?

Why do you think it's a directory structure problem? You wrote that in
the ouput you get only "In script Got here Attempting to instantiate db
object ", so it stops in MySQLDatabase. Maybe there is an error.

The one you gave is an absolute path to the file system. Do you
actually have a /db directory on your file system?

If /db is relative to your document root, the following works with any
server - Windows or Linux:

include ($_SERVER['DOCUMENT_ROOT'] . '/db/mysql_database.inc.php');

$_SERVER['DOCUMENT_ROOT'] gives the absolute path to your web site on
either system.

Perhaps because "/db/mysql_database.inc.php" is relative to the root of
the filesystem and not the PWD?
