[JJR512]

I have some code that generates a "|"-separated list of forums that users are able to see. If a user has access to the forum, it appears in the list; if he/she doesn't, it doesn't. But the way I have it now, the | character appears after every forum name. I'd like it to not appear after the last forum name. I think I need to have some way of telling if a while loop is on the last go-round, if you know what I mean...if it's the last time the loop is going to execute.

Here's what I have:

PHP Code:

// Begin Forumlinks
$forumlinksperms=$DB_site->query("SELECT forumid,title,parentid FROM forum WHERE active='1' ORDER BY displayorder");
$forumlink = "";
while ($forumlinksperm=$DB_site->fetch_array($forumlinksperms)) {
  $getperms=getpermissions($forumlinksperm[forumid]);
  if ($getperms[canview]) {
    if ($forumlinksperm[parentid]=='-1') {
      $forumlink .= "<b>$forumlinksperm[title]</b> | ";
    } else {
      $forumlink .= "$forumlinksperm[title] | ";
    }
  }
}
// End Forumlinks 


So, if I had, say, five forums, named Forum1, Forum2,...Forum5, and assuming all were accessible, you would see this:

Forum1 | Forum2 | Forum3 | Forum4 | Forum5 |

I'd like to make it so you see this:

Forum1 | Forum2 | Forum3 | Forum4 | Forum5

How can I do this?
