Not wanting this question to be too long, I will skip to an example:
If I have 2 files: paper.php and rock.php, and they contain the following:

paper.php:

include('rock.php');
$link = mysql_connect(DB_HOST, DB_USER, DB_PASS) or die("Couldn't make connection.");
$db = mysql_select_db(DB_NAME, $link) or die("Couldn't select database");

and rock.php:

define ("DB_HOST", "localhost");
define ("DB_USER", "foo");
define ("DB_PASS","bar");
define ("DB_NAME","fooDBar");

Eventually, will the user viewing my paper.php file be connected to the DB or not?

    It should work as you've coded.

    a DIY test-approach would have been much quicker than posting it here, by the way :) Yup, i often use an include-file with tons of constants like in your example, works like a charm

Yes, you define all the appropriate variables in rock.php and are including rock.php, then they will be defined for the whole program execution, including where you do a mysql_connect().
