Problems with directory removing.

Hi there,

I'm currently working on picture gallery administration tool, and I use file management functions, to upload/delete files; create and remove directories. Everything was fine until i had to make directory removing script. Of course, first of all i have to erase every file inside it:

<?
      if ($handle = opendir($path)) {
        while (false !== ($file = readdir($handle))) {
          unlink ("$path/$file");
        }

?>

After it's done I'd like to remove the directory these files were in, just simply like that:

<?
rmdir($path);
?>

BUT, however even if there is no files in the directory, there is still something left. And that something is two elements: "." and ".." (no quotes).

".." element should mean something like "Up one level in the dir" or something like that, don't know anything about "." ...

However, the file deleting loop written above can't delete those double-and-single-dot elements and i get Permission denied error.

(Notice that all other files are deleted by the loop, but those two ".." & "." are left, so visually the directory is empty, but the server doesn't accept it as the empty one because of those dots).

Furthermore i can't remove the directory because it's not empty and those dots are left which i can't delete.


OK, here are the errors that i get for you to imagine:

Warning: unlink(C:/Apache/htdocs/spoilera/nuotraukos/thumbs/testdir/.): Permission denied in c:\apache\htdocs\spoilera\admin\includes\fc.php on line 106

Warning: unlink(C:/Apache/htdocs/spoilera/nuotraukos/thumbs/testdir/..): Permission denied in c:\apache\htdocs\spoilera\admin\includes\fc.php on line 106

Warning: rmdir(): Directory not empty in c:\apache\htdocs\spoilera\admin\includes\fc.php on line 120

----

see? those dots don't let me remove the directory.

Every idea would be appreciated.

Hi


You can not remove the directory because you are still in it! use closedir (); on the $handle after your loop and before your rmdir();

Example ( as a function [ remove directories and files! ] ).....

<?

// remove all files and directories below this directory

$path = "e:/www/docs/test";

function remove ( $dir )
{
      $keep[]  = $dir;
      $remove  = array ( $dir );
      $removed = array ();

      while ( count ( $remove ) > 0 )
      {

            foreach ( $remove as $directory => $start )
            {

                  if ( $dir = @opendir ( $start ) )
                  {

                        while ( ( $file = readdir ( $dir ) ) !== false )
                        {

                              if ( ( $file != '.' ) && ( $file != '..' ) )
                              {

                                    $real = $start . '/' . $file;


                                    if ( is_dir ( $real ) )
                                    {


                                          if ( !in_array ( $real, $removed ) && !in_array ( $real, $remove ) )
                                          {

                                                $remove[] = $real;
                                                array_unshift ( $keep, $real );

                                          }

                                    } elseif ( is_file ( $real ) )
                                    {

                                          $files[] = $real;

                                    }

                              }

                        }

                        closedir($dir);

                  }

                  $removed[] = $start;

                  unset ( $remove[$directory] );

                  }

            }


            foreach ( $files as $name )
            {

                  unlink ( $name );

            }

            foreach ( $keep as $rmd )
            {

                  rmdir ( $rmd );

            }

      }

// run it

remove ( $path );

?>

A little precision. You dont have to delete . and .. these are not real files or directories.

These special names "." and ".." are used by the system to designate current working directory and parent directory respectively. So you can't delete a directory while you're working in it and of course can't delete parent. If there is only "." and ".." names - that means, that your current working directory is already empty and you can delete it from parent dir - go up one level by chdir("..") and call rmdir("testdir");
