rmdir (PHP 4, PHP 5) rmdir — delete a directory Report a bug Description bool rmdir ( string $dirname ) Attempts to delete the directory specified by dirname. The directory must be empty and must have appropriate permissions. Returns TRUE on success, or FALSE on failure. Note: Since PHP 5.0.0 rmdir() can also be used with certain URL wrapping protocols. See the list of Supported Protocols and Wrappers to see which URL wrapping protocols rmdir() supports. Note: Support for Context was added in PHP 5.0.0. See the Stream function for a description of context. Note: When safe mode is enabled, PHP will check when executing a script whether the directory being scripted has the same UID (owner) as the script being executed. See mkdir() and unlink(). example:

  2. function rrmdir($dir) {
  3. if (is_dir($dir)) {
  4. $objects = scandir($dir);
  5. foreach ($objects as $object) {
  6. if ($object != "." && $object != "..") {
  7. if (filetype($dir."/".$object) == "dir") rrmdir($dir."/".$ object); else unlink($dir."/".$object);
  8. }
  9. }
  10. reset($objects);
  11. rmdir($dir);
  12. }
  13. }
  14. ?>

This isn't my code, but just thought I would share, since it took me so long to find. This is a function to delete a folder, all sub-folders, and files in one clean move. Just tell it what directory you want deleted, in relation to the page that this function is executed. Then set $empty = true if you want the folder just emptied, but not deleted. If you set $empty = false, or just simply leave it out, the given directory will be deleted, as well.

Example:

  2. function deleteAll($directory, $empty = false) {
  3. if(substr($directory,-1) == "/") {
  4. $directory = substr($directory, 0,-1);
  5. }
  6. if(!file_exists($directory) || !is_dir($directory)) {
  7. return false;
  8. } elseif(!is_readable($directory)) {
  9. return false;
  10. } else {
  11. $directoryHandle = opendir($directory);
  12. while ($contents = readdir($directoryHandle)) {
  13. if($contents != '.' && $contents != '..') {
  14. $path = $ directory . "/" . $contents;
  15. if(is_dir($path)) {
  16. deleteAll($path);
  17. } else {
  18. unlink($path);
  19. } // bbs.it-home.org
  20. }
  21. }
  22. closedir($directoryHandle);
  23. if($empty == false) {
  24. if(!rmdir($directory)) {
  25. return false;
  26. }
  27. }
  28. return true;
  29. }
  30. }
  31. ?>

A patch to previous script to make sure rights for deletion is set: example:

  2. //Delete folder function
  3. //Recursively delete directories and files
  4. function deleteDirectory($dir) {
  5. if (!file_exists($dir)) return true;
  6. if (!is_dir ($dir) || is_link($dir)) return unlink($dir);
  7. foreach (scandir($dir) as $item) {
  8. if ($item == '.' || $item == '. .') continue;
  9. if (!deleteDirectory($dir . "/" . $item)) {
  10. chmod($dir . "/" . $item, 0777);
  11. if (!deleteDirectory($dir . "/ " . $item)) return false;
  12. };
  13. }
  14. return rmdir($dir);
  15. }
  16. ?>
