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...
