and here's the ajax.php:

<?php
header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Methods: GET, POST, PATCH');
header("Access-Control-Allow-Headers: X-Requested-With");
header('Content-Type: application/json');

$data = array(
 array("id"=>1,"name"=>"Brendan","year"=>1992),
 array("id"=>2,"name"=>"Thane","year"=>1997),
 array("id"=>3,"name"=>"Hoyt","year"=>1994),
 array("id"=>4,"name"=>"Xanthus","year"=>1991),
 array("id"=>5,"name"=>"Francis","year"=>1991),
 array("id"=>6,"name"=>"Plato","year"=>1998),
 array("id"=>7,"name"=>"Sylvester","year"=>1998)
);

 $rarray = array(); 
 $rarray['films'] = $data;
 echo json_encode($rarray);
