how to delete a folder which is empty using PHP - php

Question

<?php
function rmdirr($dirname){
// Sanity check
$dirname = "TEST/";
if (!file_exists($dirname)) {
return false;
}
// Simple delete for a file
if (is_file($dirname)) {
return unlink($dirname);
}
// Loop through the folder
$dir = dir($dirname);
while (false !== $entry = $dir->read()) {
// Skip pointers
if ($entry == "." || $entry == "..") {
continue;
}
// Recurse
unlink("$dirname/$entry");
}
// Clean up
$dir->close();
return rmdir($dirname);
}
if (rmdirr($_GET['map'])){
echo "TEST FERo";
}
else{
echo "something went wrong.";
}

Its working well and good. But if i need to delete the folder which contains some files and empty folder. In this case it delete all the files but not the empty folder. It throws an exception like…
Warning: unlink(TEST//New Folder) [function.unlink]: Permission denied
in E:\Xampp\xampp\htdocs\delete_FILE\delete_FILE.php on line 23
Warning: rmdir(TEST/) [function.rmdir]: Directory not empty in
E:\Xampp\xampp\htdocs\delete_FILE\delete_FILE.php on line 28
What is the possible way to delete even the folder is empty.

Answer 1

Just use your rmdirr function recursively in the while loop instead of unlink;
function rmdirr($dirname){
// Sanity check
if (!file_exists($dirname)) { return false; }
// Simple delete for a file
if (is_file($dirname)) { return unlink($dirname); }
// Loop through the folder
$dir = dir($dirname);
while (false !== $entry = $dir->read()) {
// Skip pointers
if ($entry == "." || $entry == "..") { continue; }
// Recurse
rmdirr("$dirname/$entry");
}
// Clean up
$dir->close();
return rmdir($dirname);
}
This way it'll also take care of non-empty subfolders...

Answer 2

you have to make sure your webserver is able to delete those files. check the permissions.

Answer 3

You are deleting the files in 1 level only. Your code tries to delete the folder TEST//New Folder using unlink instead of rmdir. You have to check if it's a folder or not, then rmdir or unlink it.
