Answer 1

Did you implement the callback on the php server properly? Like so:

$callback = $_REQUEST['callback'];

// Create the output object.
$output = array('a' => 'Apple', 'b' => 'Banana');

//start output
if ($callback) {
    header('Content-Type: text/javascript');
    echo $callback . '(' . json_encode($output) . ');';
} else {
    header('Content-Type: application/x-json');
    echo json_encode($output);
}
