In each case, you're looking for a single key called either 'URL' or  
'unit', neither of which exist. My suggestion was that you store each  
URL as its own key, e.g.:

clsMem::getMem()->set('bbc.co.uk', true, true, 600) or  die ("Could  
not write to the cache");

Then to retrieve that value:

$unit = clsMem::getMem()->get('bbc.co.uk');

One problem is that it's not clear what you're trying to achieve.  
Sticking everything in a single key is not really using memcached as  
a database at all, which is what you asked for.

If you wanted to preserve all the data you initially posted about,  
you'd need to make multiple keys for each entry, e.g. for the  
('1'=>array('yahoo.com','Yes') entry:

clsMem::getMem()->set('URL:1', 'yahoo.com', true, 600) or  die  
("Could not write to the cache");
clsMem::getMem()->set('unit:1', 'yes', true, 600) or  die ("Could not  
write to the cache");

Then you could retrieve them by:

$URL = clsMem::getMem()->get('URL:1');
$unit = clsMem::getMem()->get('unit:1');

Any clearer?
