Breadcrumb Trail for Pages

After a search online for quick and simple breadcrumb code that worked at more than one level depth, I put something together myself. Not having a personal platform to share it online, I am posting it here. It is basic and I’m sure the more experienced users can improve and extend it, but it was sufficient for my needs.

Enjoy.

The Code:

//Check if page has ancestors - if only one parent exists, this will be an empty array
if($post->ancestors){
//Reverse the array so out put starts at the top of the hierarchy
$parents = array_reverse($post->ancestors);
  foreach($parents as $parent){
     echo ' &raquo; <a href="'.get_page_link($parent).'">'.get_the_title($parent).'</a>';
  }
}
else if($post->parent){
//Deal with single parent situation
echo ' &raquo; <a href="'.get_page_link($post->parent).'">'.get_the_title($post->parent).'</a>';
}
//Present current title as simple text, no link
echo ' &raquo; ';
the_title();
