Question on PHP Syntax used in AdminCP/Index.php

[Ocean]

Hi! I have a quick question... In vBulletin 3.03's AdminCP/Index.php, you'll find the following code for the Navigation Bar:

PHP Code:

 
if (can_administer('canadminusers'))
{
$printhr = true;
construct_nav_option($vbphrase['add_new_user'], 'user.php?do=add', '|');
construct_nav_option($vbphrase['search_for_users'], 'user.php?do=modify', '|');
construct_nav_option($vbphrase['merge_users'], 'usertools.php?do=merge', '|');
construct_nav_option($vbphrase['ban_user'], "../$modcpdir/banning.php?do=banuser", '<br />');
construct_nav_option($vbphrase['prune_users'], 'user.php?do=prune', '|');
construct_nav_option($vbphrase['private_message_statistics'], 'usertools.php?do=pmstats', '<br />');
construct_nav_option($vbphrase['referrals'], 'usertools.php?do=referrers', '|');
construct_nav_option($vbphrase['search_ip_addresses'], 'usertools.php?do=doips', '<br />');
construct_nav_option($vbphrase['view_banned_users'], "../$modcpdir/banning.php?do=modify", '<br />');
construct_nav_option($vbphrase['send_email_to_users'], 'email.php?do=start', '|');
construct_nav_option($vbphrase['generate_mailing_list'], 'email.php?do=genlist', '<br />');
construct_nav_option($vbphrase['access_masks'], 'accessmask.php?do=modify', '<br />');
construct_nav_group($vbphrase['users']);
} 


Here's my question... Some of those lines end in '|', while others end in '<br />'.

Looking at the code, I can't figure out why a line would require one as opposed to the other.


So far, people on vBulletin.com are stumped.


Can anyone help enlighten me on this?

Thanks!
