Breadcrumbs problems

AdRock

I have been searching for a breadcrumbs script for weeks and keep getting pointed to this one

http://www.zend.com/zend/spotlight/breadcrumb28.php

Every time i try an call the function, it displays all of the code and I get this error

Fatal error: Call to undefined function breadcrumb_nav() in d:\Apache\Apache\htdocs\index.php on line 10

Here is the code (I don't know if I have got it right)

<?php 
$bc_site = (isset($HTTP_HOST)) ? "http://$HTTP_HOST/" : "http://yoursitenamehere.com/"; 

$bc_label =  array("faq"=>"Frequent Questions", 
                     "links"=>"Links", 
                        "contact"=>"Contact Info" 
                        ); 
?> 

function breadcrumb_nav($basename = "Home") { 

   global $PHP_SELF, $bc_site, $bc_label; 

   $site = $bc_site; 
   $return_str = "<A HREF=\"/\">$basename</A>"; 
   $str = substr(dirname($PHP_SELF), 1); 

   $arr = split('/', $str); 
   $num = count($arr); 

   if ($num > 1){ 

  foreach($arr as $val) { 

     $return_str .= ' &gt; <a href="'.$site.$val.'/">'.$bc_label[$val].'</a>'; 
     $site .= $val.'/'; 

  } 

   } elseif($num == 1) { 

  $arr = $str; 
  $return_str .= ' &gt; <a href="'.$bc_site.$arr.'/">'.$bc_label[$arr].'</a>'; 

   } 

   return $return_str; 

} 
?>

and I include/call the function using

<?php
include 'breadcrumb.php';
breadcrumb_nav();
?>

If anyone can help it would be a huge weight off my mind as this is really doing my head in

Right.......I can't beleive how blind I am. I have now sorted out what I did wrong but I have another question

How do I change this line

$bc_site = (isset($HTTP_HOST)) ? "http://$HTTP_HOST/" : "http://yoursitenamehere.com/";

to localhost so i can test it locally?

$bc_site = "http://localhost/";

Also, instead of using things like $HTTP_HOST or $PHP_SELF, you should be using $_SERVER['HTTP_HOST'] and the like, and you should turn off register_globals. For more information, search the board or Google for the security risks this directive presents.

For more information on $SERVER and the other superglobal arrays (e.g. $POST and $_GET), see this man page: [man]variables.predefined[/b].

I had an idea but don't really know if i can change the code i found.

That code I presume looks in a directory and creates breadcrumbs for any files it finds.....

...but can I create an array with a list of files i.e. contact.php and depending on what page is on use a $_GET to get hte page name and display it in the breadcrumbs?
