jquery json with arrays with numerical keys

If i have a php file that outputs json data with numerical keys, like

<?php
$array[1] = "abcd";
$array[2] = "efgh";
$array[3] = "1234";
$array[4] = "5678";

echo json_encode($array);
?>

how do i access the value for say key 4? The integer in "data.4" below is breaking the code. Any help would be greatly appreciated. Thanks!

    $.ajax({
         type: "GET",
         url: "http://localhost:8888/myapp/json/json_data",
         async: false,
         beforeSend: function(x) {
          if(x && x.overrideMimeType) {
           x.overrideMimeType("application/j-son;charset=UTF-8");
          }
     },
     dataType: "json",
     success: function(data){
        //$("#box").html(JSON.stringify(data, null, 4));
        $("#box").append("<br/>" + data.4)
     }
    });

Use brackets to access the property: data['4'].

Note: Your PHP is not returning an array, but an object: {"1":"abcd","2":"efgh","3":"1234","4":"5678"}.

PS. You've got a typo in your overrideMimeType. You shouldn't have to override this though, because you're using jQuery. For an alternative, see $.getJSON.
