How to chdir() more than once

I have a file.php that before I include it, use chdir() to resource from a subfolder. However file.php calls chdir() as well, for its includes and it throws:

Warning: chdir() [function.chdir]: No error (errno 0) in C:\wamp\www\a\test.php on line 4
Warning: include(test2.php) [function.include]: failed to open stream: No such file or directory in C:\wamp\www\a\test.php on line 5
Warning: include() [function.include]: Failed opening 'test2.php' for inclusion (include_path='.;C:\php5\pear') in C:\wamp\www\rob\a\test.php on line 5

Below is the three files i'm using to test this:
------------------ C:\wamp\www\index.php -------------------------
<?php
 
echo 'Changing dir to a...<br />';
chdir('a/');
include('test.php');
 
?>
 
------------------ C:\wamp\www\a\test.php -------------------------
I'm in folder 'a'<br />
<?php 
echo 'changing folder to b...';
chdir('b/');
include ('test2.php');
 ?>
 
 
------------------ C:\wamp\www\b\test2.php -------------------------
i'm in folder b

it's because you have to orient our self to the new directory

so the first chdir()

puts you from

EXAMPLE:
/public_html/www

to
/public_html/www/a

which is now your working directory

so chir('b/'); being called after words is trying to change to

/public_html/www/a/b
which probably doesn't exist.

you need to  change it to

chdir('../b/');

which will then change it to
/public_html/www/b

I'm not sure include will take in to account the chdir before it because I've never needed to do it that way. Also, what is the reason you are doing it that way instead of:

include('a/test.php');

or

include ('b/test2.php');

?
