Delete all files and folders in a directory

LocalWriteTest.php

<?php
        $this->path = BASE_FOLDER . '/x/y/z';

        if (file_exists($this->path)) {

            $objects = new RecursiveIteratorIterator (
                new RecursiveDirectoryIterator($this->path),
                RecursiveIteratorIterator::SELF_FIRST);

            $directories = array();

            $i = 0;
            
            /** Recursive process of Folders */
            foreach ($objects as $name => $object) {

                /** Remove files as found */
                if (is_file($name)) {
                    unlink($name);
                    
                /** Hold folders until end */
                } elseif (is_dir($name)) {
                    $directories[$i++] = $name;
                }
            }
                
            /** Sort folders in reverse order and delete one at a time */        
            arsort($directories);
            foreach ($directories as $name) {
                rmdir($name);
            }

            /** Remove the seed path folder */
            rmdir($this->path);
        }
?>

Would it make sense to initialize $directories with $this -> path, so the directory removal loop will remove it. This will eliminate the need to have a separate, final rmdir

Also, apparently (I've not written much php at all), arrays can be added to as
$directories[] = $name

which will add $name at the next highest index. So, if you initialize the array as
$directories = array(0 => $this->path)

then the added arrays found during the looping will just add at numerical index 1, 2, 3, 4, etc.
This eliminates the need for the $i index variable (never fun to have one of those floating around)

If I wrote this, also, I'd probably do a loop gathering up the files and directories into 2 lists, then loop over them to do the action.
I'm not a huge fan of mixing the discovery with the action, especially since the discovery phase (looping over $objects) has 2 possible outcomes: deleting a file or adding a directory to a list. By mixing the "discovery" and "action" phases, the code becomes a bit more difficult to change. For example, if you find a better way to do the recursive looping, you might have a harder time extracting it out. So, I'd probably do

foreach ($objects as $name => $object) {
  if (is_file($name)) {
    $files[] = $name;
  } elseif (is_dir($name)) {
    $directories[] = $name;
  }
}

/** now loop over $files and unlink them **/
/** followed by looping over $directories and rmdir them **/

There we go. Got github to let me fork it. Here are my thoughts in the actual script:
