[PHP] Breadcrumbs help

[Sebastian]

hello all.

this code creates dynamic breadcrumbs, ie: home > site nav > community

I am having a bit of a time trying to make it so it doesn't hyperlink the
current page thats being viewed, any help is appreciated.

<?

       $LocationMappings = array(
        "view.php"   => "site map",
        "company"   => "about",
        "articles"  => "news"
        );

function LocatorLine()
{
       global $SCRIPT_NAME, $LocationMappings;
       $file=1; // 1 Doesn't show the file name, 0 Does

       $locationArray = explode("/",$SCRIPT_NAME);
       $locationHref = "";

       echo '<span class="smalltext">:: <a href="/">main page</a></span>';
       for($i=1; $i<count($locationArray)-$file; $i++)
       {
          if ( !empty($LocationMappings[$locationArray[$i]]) ) {
             $locationText = $LocationMappings[$locationArray[$i]];
          }
          else {
             $locationText = ucwords($locationArray[$i]);  //Uppercase
letters
          }
          $locationHref .= "/" . $locationArray[$i];
          echo "&nbsp;<b>&raquo;</b>&nbsp;<a
href=\"$locationHref\">$locationText</a>";
       }
       echo "\n";
}

LocatorLine()
?>

cheers,
