                                    dirname

   (PHP 3, PHP 4 )
   dirname -- Returns directory name component of path

Description

   string dirname ( string path)

   Given a string containing a path to a file, this function will return
   the name of the directory.

   On Windows, both slash (/) and backslash (\) are used as path
   separator character. In other environments, it is the forward slash
   (/).

   Example 1. dirname() example
   <?php
   $path = "/etc/passwd";
   $file = dirname($path); // $file is set to "/etc"
   ?>

     Note: In PHP 4.0.3, dirname() was fixed to be POSIX-compliant.
     Essentially, this means that if there are no slashes in path , a
     dot ('.') is returned, indicating the current directory. Otherwise,
     the returned string is path with any trailing /component removed.
     Note that this means that you will often get a slash or a dot back
     from dirname() in situations where the older functionality would
     have given you the empty string.

   See also basename(), pathinfo(), and realpath().
