Should a directory path variable end with a trailing slash?

Question

When defining a path to a directory as a variable or constant, should it end with a trailing slash? What is the convention?

I don't include the trailing slash when I, for example, define a directory for storing files. That is because I will use it like

$store_file = "$store_path/$file_id";

I will always add a trailing slash before using a variable that's supposed to hold a directory path. I think it's better to always add one than to wonder if the trailing slash is included.
