breadcrumb classes.

I am looking for a breadcrumb class in PHP that does not rely on the
directory structure to build the trail.

I have been using Richard Baskettes -
http://www.baskettcase.com/classes/breadcrumb/ - breadcrumb classes and
they are great... BUT. I have a site that is being built using
templates and the directory hierarchy can not be used to create the
trail.

Sorry if you read this post in alt.lang.php.

Thanks.

Is a class really needed for breadcrumbs? For my blog navigation (my
weblog script) I simply just use a function that goes along with my
template engine.

Example:

<?php
$output = breadcrumb("{b Index}index.php{/b} {s} {b
Options}index.php?options{/b}", "||");

function breadcrumb($data,$sep) {
$breadcrumb = str_replace("{s}", $sep, $data);
$breadcrumb = preg_replace("#{b (.*?)}(.*?){/b}#s", "<a
href=\"\\2\">\\1</a>", $breadcrumb);
return $breadcrumb;
}


print($output);
?>

Will create a simple breadcrum setup, and you could just display the
navigation depending on the page load (example):

$output = breadcrumb("{b
".$_GET['id']."}index.php?id=".$_GET['id']."{/b}", "||");
Depends on how advanced you want to get.
