Question

I am making a php file which will return json data to javascript file. Currently it only returns the last json object and ignores the rest of them. Here is my php code

$arr = array(
  "cartId" => 456186,
  "lastModified" => "Tue, 19 Jan 2010 03:14:07 GMT",
  "items" => array(
    15642,
    45616,
    54984,
    45751
  ),
  "cartId" => 456187,
  "lastModified" => "Tue, 20 Jan 2010 04:14:07 GMT",
  "items" => array(
    'item' => 15643,
    'item' => 45617,
    'item' => 54985,
    'item' => 45752
  )
);
echo json_encode($arr);

above code returns following

{"cartId":456187,"lastModified":"Tue, 20 Jan 2010 04:14:07 GMT","items":{"item":45752}}

How can I resolve this issue?

Answer 1

The first elements are being overwritten with the second elements as their keys are same. Same with the items array in the second item.

Try

$arr = array (
  array(
    "cartId"       => 456186,
    "lastModified" => "Tue, 19 Jan 2010 03:14:07 GMT",
    "items"        => array(
      15642,
      45616,
      54984,
      45751, 
    ),
  ),
  array(
    "cartId"       => 456187,
    "lastModified" => "Tue, 20 Jan 2010 04:14:07 GMT",
    "items"        => array(
      15643,
      45617,
      54985,
      45752, 
    ),
  ), 
);
