Add a php code

I am using WordPress SEO by Yoast and it allows me to show breadcrumbs in theme, It gave me a php code as below:

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

Now i want to add it above title of posts and tags ( I want to show them on post’s pages and tags pages). but i don’t know how and where should i place it. Can you please help me?
