What's Wrong With My Code?

[noonespecial]

Can someone explain what I'm doing wrong?

PHP Code:

$entry= $db->query_first("SELECT tags FROM " . TABLE_PREFIX . "journal_entries WHERE journal_id=1");
        
$entry['tags'] = stripslashes($entry['tags']);            
if ($entry['tags'])
{
        $kwords = explode(',', trim($entry['tags']));
        $entry['tags'] = '';
        foreach ($kwords AS $keyword)
        {    
        $keyword = trim($keyword);
        $entry['tags'] .='<a href="/journal.php?' .$vbulletin->session->vars['sessionurl']. 'do=showjournal&amp;tag='.$keyword.'&amp;j='.$j.'" target="_top">' .$keyword. '</a>, ';
            
        }
        $entry['tags']= substr_replace($entry['tags'],'',-2);
    }
            
   eval('print_output("' . fetch_template('journal_blogcloud') . '");');
$db->free_result($entry); 


I'm trying to get this to export all the "tags" (separated by a comma) by a journal ID.

What's wrong with my code?
