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.
