If I am using some kind of breadcrumb, I tend to take the easy route:
Say I was viewing Truck tires (as in your previous example), my URI
would look like this:
/automotive/tires/truck/
Then for the breadcrumb, I'll just do something similar to:
<?php
$tmp=explode('/',$_SERVER['REQUEST_URI']);
$num_levels=count($tmp);
$nav=array();
for($i=$num_levels-1;$i>0;$i--){
if(empty($tmp[$i])){
// in case there were two slashes together
// in the URI, or if it ended with a slash.
// **this will not add the top level link "/"
array_pop($tmp);
continue;
}else{
// if URI started with a slash, then the first
// element will be empty, leaving us with the
// leading slash.
$nav[]='<a href="'.join('/',$tmp).'/">'.
ucwords($tmp[$i]).'</a>';
array_pop($tmp);
}
}
$nav=array_reverse($nav);
echo join(" » ",$nav);
?>
