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...
