Yoast breadcrumbs – adding PHP to a template

Hello,

I recently installed Yoast SEO for WordPress on my Twentyeleven child theme. I am trying to activate Yoast’s in-built Breadcrumb feature but am having trouble.

I see that Yoast outlines some php and and asks users to insert it in their ‘single.php’ so that the breadcrumb menu appears just below the main nav bar.

<?php if ( function_exists('yoast_breadcrumb') ) {
yoast_breadcrumb('<p id="breadcrumbs">','</p>');

My question is…

Can this php go anywhere in the ‘single.php’ or does it have to go in a specific place. I have managed to get it working, however, this result just came from dumping the code in a random place Example of breadcrumbs on my site’s ‘single.php’
