Changing directories in PHP

[xcmir]

How do I change directories in PHP???

 

I have a php script which sends information to a template script to be processed, code like this:

$site_root = "./././";
$categories_search_box = $template->process($site_root.'search.tpl.php');

 

the file search.tpl.php is in the root directory of my website and my php script is 3 sub directories before, However I cannot seem to access my root directory, I have tried both using ./././ and ../../../What is the problem????

 

I am getting this error message:"Warning: template::include() [function.include]: Failed opening 'themes/modern_silver/templates/././search.tpl.php' for inclusion (include_path='.;C:\AppServ\php5\pear') in C:\AppServ\www\1\includes\class_template.php on line 47"

this will give you the server root and then you can start from there

 

<?php include($_SERVER['DOCUMENT_ROOT'].'/pathtofile/TheFILE.php'); ?>

<?php
$dir = "../../../";

chdir($dir);

?>
