'simple' code that works and can be read by a ten year old:

function deleteNonEmptyDir($dir) 
{
   if (is_dir($dir)) 
   {
        $objects = scandir($dir);

        foreach ($objects as $object) 
        {
            if ($object != "." && $object != "..") 
            {
                if (filetype($dir . "/" . $object) == "dir")
                {
                    deleteNonEmptyDir($dir . "/" . $object); 
                }
                else
                {
                    unlink($dir . "/" . $object);
                }
            }
        }

        reset($objects);
        rmdir($dir);
    }
}

Please note that all I did was expand/simplify and fix (didn't work for non empty dir) the solution here: In PHP how do I recursively remove all folders that aren't empty?

    public static function remove($path)

        }

        array_push($results, $dir);

        return $results;
    }

    public static function rrmdir($dir)
    {
        $files = self::rscandir($dir);

        foreach($files as $file)
        self::remove($file);

        return !file_exists($dir);
    }
}

?>

cleanup.php :

<?php

/* include.. */

filesystem::rrmdir('/var/log');
filesystem::rrmdir('./cache');

Building on The Pixel Developer's comment, a snippet using the SPL might look like:

$files = new RecursiveIteratorIterator(
    new RecursiveDirectoryIterator($dir, RecursiveDirectoryIterator::SKIP_DOTS),
    RecursiveIteratorIterator::CHILD_FIRST
);

foreach ($files as $fileinfo) {
    $todo = ($fileinfo->isDir() ? 'rmdir' : 'unlink');
    $todo($fileinfo->getRealPath());
}

rmdir($dir);

Note: It does no sanity checking and makes use of the SKIP_DOTS flag introduced with the FilesystemIterator in PHP 5.3.0. Of course, the $todo could be an if/else. The important point is that CHILD_FIRST is used to iterate over the children (files) first before their parent (folders).

Something like this?

function delete_folder($folder) {
    $glob = glob($folder);
    foreach ($glob as $g) {
        if (!is_dir($g)) {
            unlink($g);
        } else {
            delete_folder("$g/*");
            rmdir($g);
        }
    }
}

unlinkr function recursively deletes all the folders and files in given path by making sure it doesn't delete the script itself.

function unlinkr($dir, $pattern = "*") {
    // find all files and folders matching pattern
    $files = glob($dir . "/$pattern"); 

    //interate thorugh the files and folders
    foreach($files as $file){ 
    //if it is a directory then re-call unlinkr function to delete files inside this directory     
        if (is_dir($file) and !in_array($file, array('..', '.')))  {
            echo "<p>opening directory $file </p>";
            unlinkr($file, $pattern);
            //remove the directory itself
            echo "<p> deleting directory $file </p>";
            rmdir($file);
        } else if(is_file($file) and ($file != __FILE__)) {
            // make sure you don't delete the current script
            echo "<p>deleting file $file </p>";
            unlink($file); 
        }
    }
}

if you want to delete all files and folders where you place this script then call it as following

//get current working directory
$dir = getcwd();
unlinkr($dir);

if you want to just delete just php files then call it as following

unlinkr($dir, "*.php");

you can use any other path to delete the files as well

unlinkr("/home/user/temp");

This will delete all files in home/user/temp directory.

I use this code ...

 function rmDirectory($dir) {
        foreach(glob($dir . '/*') as $file) {
            if(is_dir($file))
                rrmdir($file);
            else
                unlink($file);
        }
        rmdir($dir);
    }

or this one...

<?php 
public static function delTree($dir) { 
   $files = array_diff(scandir($dir), array('.','..')); 
    foreach ($files as $file) { 
      (is_dir("$dir/$file")) ? delTree("$dir/$file") : unlink("$dir/$file"); 
    } 
    return rmdir($dir); 
  } 
?>
