Yes i know, maybe i am wrong.

PHP Code:

while ($author = $DB_site->fetch_array($artbyauthorquery)) 
{ 
    $author_cache[$author['author']][] = $author; 
} 


Would give something like the following (assuming some about the author table now):
$author_cache['jim'][0] = array('jim','doe','UK',3,......)
$author_cache['john'][0] = array('john','smith','germany',4,......)

now you ask for the entry "$author_cache['author']" unless there is an author named 'author', this would give no results.

Maybe i am looking complete wrong now, but just shoot me i am wearing a bullet proof vest
