// This function will take $_SERVER['REQUEST_URI'] and build a breadcrumb based on the user's current path
function breadcrumbs($separator = ' &raquo; ', $home = 'Home')
{
    // This gets the REQUEST_URI (/path/to/file.php), splits the string (using '/') into an array, and then filters out any empty values
    $path = array_filter(explode('/', parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH)));

    // This will build our "base URL" ... Also accounts for HTTPS :)
    $base = ($_SERVER['HTTPS'] ? 'https' : 'http') . '://' . $_SERVER['HTTP_HOST'] . '/';

    // Initialize a temporary array with our breadcrumbs. (starting with our home page, which I'm assuming will be the base URL)
    $breadcrumbs = array("<a href=\"$base\">$home</a>");

    // Initialize crumbs to track path for proper link
    $crumbs = '';

    // Find out the index for the last value in our path array
    $last = end(array_keys($path));

    // Build the rest of the breadcrumbs
    foreach ($path as $x => $crumb) {
        // Our "title" is the text that will be displayed (strip out .php and turn '_' into a space)
        $title = ucwords(str_replace(array('.php', '_', '%20'), array('', ' ', ' '), $crumb));

        // If we are not on the last index, then display an <a> tag
        if ($x != $last) {
            $breadcrumbs[] = "<a href=\"$base$crumbs$crumb\">$title</a>";
            $crumbs .= $crumb . '/';
        }
        // Otherwise, just display the title (minus)
        else {
            $breadcrumbs[] = $title;
        }

    }

    // Build our temporary array (pieces of bread) into one big string :)
    return implode($separator, $breadcrumbs);
}

?>

<?php
// Default options - Home » Page Title
// echo breadcrumbs();

// Change » to >
echo breadcrumbs(' > ');

// Change 'Home' to 'Index' and » to ^^
// echo breadcrumbs(' ^^ ', 'Index');
?>

I ran into this and came up with a fix by adding a crumbs (note plural) to add the crumb with a '/'. only 2 lines of code needed:

// This function will take $_SERVER['REQUEST_URI'] and build a breadcrumb based on the user's current path
function breadcrumbs($separator = ' » ', $home = 'Home') {
    // This gets the REQUEST_URI (/path/to/file.php), splits the string (using '/') into an array, and then filters out any empty values
    $path = array_filter(explode('/', parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH)));

    // This will build our "base URL" ... Also accounts for HTTPS :)
    $base = ($_SERVER['HTTPS'] ? 'https' : 'http') . '://' . $_SERVER['HTTP_HOST'] . '/';

    // Initialize a temporary array with our breadcrumbs. (starting with our home page, which I'm assuming will be the base URL)
    $breadcrumbs = Array("<a href=\"$base\">$home</a>");

    // Initialize crumbs to track path for proper link
    $crumbs='';

    // Find out the index for the last value in our path array
    $last = end(array_keys($path));

    // Build the rest of the breadcrumbs
    foreach ($path AS $x => $crumb) {
        // Our "title" is the text that will be displayed (strip out .php and turn '_' into a space)
        $title = ucwords(str_replace(Array('.php', '_', '%20'), Array('', ' ', ' '), $crumb));

        // If we are not on the last index, then display an <a> tag
        if ($x != $last) {
            $breadcrumbs[] = "<a href=\"$base$crumbs$crumb\">$title</a>";
    	    $crumbs .= $crumb.'/';
        }
        // Otherwise, just display the title (minus)
        else
            $breadcrumbs[] = $title;
    }

It appears that my email notifications finally started working again....
