Another simple way to recursively delete a directory that is not empty:

<?php
 
function rrmdir($dir) {
   if (
is_dir($dir)) {
    
$objects = scandir($dir);
     foreach (
$objects as $object) {
       if (
$object != "." && $object != "..") {
         if (
filetype($dir."/".$object) == "dir") rrmdir($dir."/".$object); else unlink($dir."/".$object);
       }
     }
    
reset($objects);
    
rmdir($dir);
   }
 }
?>

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.

<?php
function deleteAll($directory, $empty = false) {
    if(
substr($directory,-1) == "/") {
       
$directory = substr($directory,0,-1);
    }

    if(!
file_exists($directory) || !is_dir($directory)) {
        return
false;
    } elseif(!
is_readable($directory)) {
        return
false;
    } else {
       
$directoryHandle = opendir($directory);
       
        while (
$contents = readdir($directoryHandle)) {
            if(
$contents != '.' && $contents != '..') {
               
$path = $directory . "/" . $contents;
               
                if(
is_dir($path)) {
                   
deleteAll($path);
                } else {
                   
unlink($path);
                }
            }
        }
       
       
closedir($directoryHandle);

        if(
$empty == false) {
            if(!
rmdir($directory)) {
                return
false;
            }
        }
       
        return
true;
    }
}
?>

The function delTree is dangerous when you dont take really care. I for example always deleted a temporary directory with it. Everthing went fine until the moment where the var containing this temporary directory wasnt set. The var didnt contain the path but an empty string. The function delTree  was called and deleted all the files at my host!
So dont use this function when you dont have a proper handling coded. Dont think about using this function only for testing without such a handling.
Luckily nothing is lost because I had the local copy...

Say, you're working on Windows and continue to get a permission's error without a reason. Then it may be that a different Windows program is working on the folder (see earlier notes also). In the case that you can't find that program, the line

<?php closedir(opendir($dirname)); ?>

may solve the problem!
Make sure to write this before rmdir($dirname);.

Sometimes you would face situations in which rmdir($dirname) would give "permission denied" errors though you may have changed $dirname permissions. In such situations just change the permissions of the directory which contains $dirname and rmdir($dirname) would work like a charm.
Say you use rmdir('dirr'); then change the permissions of the folder that contains 'dirr'.

I had situation where the rmdir was returning warning message as within last loop it was already removed. So here is quick fix by adding is_dir to the DelTree routine below

<?php
function delTree($dir) {
   
$files = glob( $dir . '*', GLOB_MARK );
    foreach(
$files as $file ){
        if(
substr( $file, -1 ) == '/' )
           
delTree( $file );
        else
           
unlink( $file );
    }
   
    if (
is_dir($dir)) rmdir( $dir );
   
}
?>

I wasn't having much luck with the recursive delete functions below, so I wrote my own:

<?php
// ensure $dir ends with a slash
function delTree($dir) {
   
$files = glob( $dir . '*', GLOB_MARK );
    foreach(
$files as $file ){
        if(
substr( $file, -1 ) == '/' )
           
delTree( $file );
        else
           
unlink( $file );
    }
   
rmdir( $dir );
}
?>

Simple.  Works.

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

<?php
//Delete folder function
function deleteDirectory($dir) {
    if (!
file_exists($dir)) return true;
    if (!
is_dir($dir) || is_link($dir)) return unlink($dir);
        foreach (
scandir($dir) as $item) {
            if (
$item == '.' || $item == '..') continue;
            if (!
deleteDirectory($dir . "/" . $item)) {
               
chmod($dir . "/" . $item, 0777);
                if (!
deleteDirectory($dir . "/" . $item)) return false;
            };
        }
        return
rmdir($dir);
    }
?>

if you opened a dir with opendir() you must closedir() before try to execute rmdir() or you will get a "permision denied" error on windows systems.

Wrong:

<?php
$handle
= opendir($dirpath);
//do whatever you need
rmdir($dirpath);
?>

Right:

<?php
$handle
= opendir($dirpath);
//do whatever you need
closedir($handle)
rmdir($dirpath);
?>

In case you're trying to rmdir() and you keep getting 'Permission denied' errors, make sure you don't have the directory still open after using opendir(). Especially when writing recursive functions for deleting directories, make sure you have closedir() BEFORE rmdir().

I've noticed that when using this command on a windows platform you may encounter a permissions error which may seem unwarranted. This commonly occurs if you are or were using a program to edit something in the to be deleted folder and either the item is still in the folder or the program that was accessing the file in that folder is still running(causing it to hold onto the folder).

SO... if you get a permissions error and there shouldn't be an issue with folder permissions check if there are files in there then check if there is a program running that is or was using a file that was in that folder and kill it.
