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...
