Get parent directory of running script

Question

In PHP  what would be the cleanest way to get the parent directory of the current running script relative to the www root  Assume I have     SERVER  SCRIPT NAME        relative path to script index php    Or just    something else      relative path to script     And I need to get  relative path to  with slashes properly inserted  What would you suggest  A one liner is preferred   EDIT  I need to get a path relative to the www root  dirname   FILE    gives me an absolute path in the filesystem so that won t work    SERVER  SCRIPT NAME   on the other hand  starts  at the www root

Here is what I use since I am not running   5 2  function getCurrentOrParentDirectory  type  current         if   type     current              path   dirname   FILE             else            path   dirname dirname   FILE                 position   strrpos  path         1      return substr  path   position       Double dirname with file as suggested by  mike b for the parent directory  and current directory is found by just using that syntax once   Note this function only returns the NAME  slashes have to be added afterwards

As of PHP 5 3 0 you can use   DIR   for this purpose      The directory of the file  If used inside an include  the directory of   the included file is returned  This is equivalent to   dirname    FILE       See PHP Magic constants   C  www gt php --version PHP 5 5 6  cli   built  Nov 12 2013 11 33 44  Copyright  c  1997-2013 The PHP Group Zend Engine v2 5 0  Copyright  c  1998-2013 Zend Technologies  C  www gt php -r  echo   DIR     C  www
