#This is pretty strange.
#I didn't even know how to describe this

$db = array(
-1 => array('field0', 'field1', 'field2'),
'field0' => array(9, 2, 4, 8),
'field1' => array(333, 111, 333, 1),
'field2' => array(101010, 1, 22, 1111)

    foreach($db[-1] as $fieldname){
        $db[$i][$fieldname] = &$db[$fieldname][$i];

#will print the same value (2)
echo $db['field0'][1];
echo $db[1]['field0'];

#we change $db['field0'][1]
$db['field0'][1] = 2000;

#will still print the same value (2000)
echo $db['field0'][1];
echo $db[1]['field0'];

array_multisort($db['field0'], $db['field1']);

#we change $db['field0'][1]
$db['field0'][1] = 600;

#will print 600
echo $db['field0'][1];
#will print 2000
echo $db[1]['field0'];

#the two values have been 'unlinked'?

/* PLEASE NOTE this will work:
array_multisort($db[0], $db[1]);

#we change $db['field0'][1]
$db['field0'][1] = 600;

#will print the same value (600)
echo $db['field0'][1];
echo $db[1]['field0'];
