both functions ARE working!!!

each element of BOTH arrays are different objects. they all have memory
addresses that are different. if you expect php to use esp to somehow know
that 'id' is the interface of each object by which it should determine merge
or uniqueness, think again.

try this:

class foo
{
var $bar = 'hello world';
function foo($message = null)
{
if (is_null($message)){ return; }
$bar = $message;
}
}

$sameFoo = new foo();

$arrayOne[] = $sameFoo;
$arrayOne[] = new foo('sup doc');
$arrayTwo[] = $sameFoo;
$arrayTwo[] = new foo('y i odda');

$mergedArray = array_merge($arrayOne, $arrayTwo);
echo "<pre>" . print_r($mergedArray, true) . "</pre>";

and so on...

you'll see everything works just fine.

change that last line to:

$this->bar = $message;
