PHP Header json

By adding a header with content type as JSON:

$result = array('menu1' => 'home', 'menu2' => 'code php', 'menu3' => 'about');
//return the json response:
header('Content-Type: application/json'); // <-- header declaration
echo json_encode($result, true); // <--- encode

The header is there so your app can detect what data was returned and how it should handle it.
Note that: the content header is just information about type of returned data.
If you are using UTF-8, you can use:

header("Content-Type: application/json;charset=utf-8");

Example jQuery:

 console.table('json ',data);
 console.log('Menu1: ', data.menu1);
