I think you could also use array_keys() and then get the nth key.
Something like this (untested and without any error checking):

function getElement(array $array, $index) {
$keys = array_keys($array);
return $array[$keys[$index]];
}

Wrap the whole thing into your own array class and you could even do

$foo = $array['foo'];
$bar = $array[5];

where the first statement would directly return the element with the key
'foo' and the second one the element at the 6th position, regardless of
the keys (using the function from above).

Just a quick idea.
