Answer 1

I'd do it like this...

 0) {
    $link = '/' . implode($dirs, '/');
    $text = array_pop($dirs);
    $breadcrumb = "$text" . $breadcrumb;
    if (count($dirs) > 0) {
        $breadcrumb = ' >> ' . $breadcrumb;
    }
}

echo $breadcrumb;

If you are getting this path based on the URL you shouldn't need to use DIRECTORY_SEPARATOR because URLs should always use /. If it is derived from the filesystem path you would need to swap it in instead of '/' on line 4.
