If you wish to get a part of path you can use function like this:

<?php
/**
 * Return a part of path by depth
 *
 * @param $path string
 * @param $depth int
 * @return mixed string on success, false on failure
 */
function getPartPath($path = '', $depth = 0) {
   
$pathArray = array();
   
$pathArray = explode(DIRECTORY_SEPARATOR, trim($path, DIRECTORY_SEPARATOR));  
    if(
$depth < 0)
       
$depth = count($pathArray)+$depth;

    if(!isset(
$pathArray[$depth]))
        return
false;
    return
$pathArray[$depth];
}
?>

usage:

<?php
$a
= "/var/www/foo/trunk/bar/tools/php/simplelocal";

var_dump(getPartPath($a, -2)); // returns php
var_dump(getPartPath($a, 0)); // returns var
var_dump(getPartPath($a, -1)); // returns simplelocal
?>

etc...

Regards.
