recursion - A recursive remove directory function for PHP?

Question

I am using PHP to move the contents of a images subfolder

GalleryName/images/

into another folder. After the move, I need to delete the GalleryName directory and everything else inside it.

I know that rmdir() won't work unless the directory is empty. I've spent a while trying to build a recursive function to scandir() starting from the top and then unlink() if it's a file and scandir() if it's a directory, then rmdir() each empty directory as I go.

So far it's not working exactly right, and I began to think -- isn't this a ridiculously simple function that PHP should be able to do? Removing a directory?

So is there something I'm missing? Or is there at least a proven function that people use for this action?

Any help would be appreciated.

PS I trust you all here more than the comments on the php.net site -- there are hundreds of functions there but I am interested to hear if any of you here recommend one over others.

What about this?

function rmdir_recursive($dirPath){
    if(!empty($dirPath) && is_dir($dirPath) ){
        $dirObj= new RecursiveDirectoryIterator($dirPath, RecursiveDirectoryIterator::SKIP_DOTS); //upper dirs not included,otherwise DISASTER HAPPENS :)
        $files = new RecursiveIteratorIterator($dirObj, RecursiveIteratorIterator::CHILD_FIRST);
        foreach ($files as $path) 
            $path->isDir() && !$path->isLink() ? rmdir($path->getPathname()) : unlink($path->getPathname());
        rmdir($dirPath);
        return true;
    }
    return false;
}
