HowTo: Breadcrumb Navigation Coding

Breadcrumbs are the site navigation of choice for a lot of sites. It helps visitors know where they are on your site and allow them to easily find the homepage and the upper layer of the current page. Breadcrumbs are also great for those sites with tons of links within the content pages.
Breadcrumbs are also great as a secondary site navigation. I love having both the site structure and breadcrumb. It helps the user easily find what they are looking for, fast, throughout the entire site.
Not only this, but breadcrumbs are great spider food.
The downside of breadcrumbs is the lengthy amount of time typing in every single link back to the homepage and every layer above it. This is why PHP along with other scripting languages are great. You can automate the entire process by just adding a simple tag to each page.
