A recursive remove directory function for PHP?

by

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;
}
