Generally you want to use json_encode on arrays. So your PHP array would look like:

$arr = array('foo' => 1, 'bar' => 2, 'baz' => 'test');
// you can probably just use $_POST here, i.e. $arr = $_POST

echo json_encode($arr);

And your JavaScript dealing with that data variable would look like this:

$('#id').html(data.foo + "
" + data.bar + "
" + data.baz);

This lets you deal with your data piecewise, rather than in one lump, so it's easier to manipulate and parse.
