How to send an array(multidimensional/associative) and some variables together through json?

Question

I have a multidimensional array

$output=Array
    (
        [0] => Array
            (
                [0] => mov_1
                [1] => MY FAIR LADY
            )

        [1] => Array
            (
                [1] => mov_10
                [2] => love actually
            )
    )
    and two variables
    $avlblQnty=50
    $success= true

when i send these data via json

echo json_encode( array('movieData'=>$output,'stock'=>$avlblQnty,'sucess'=>$success));

it returns

{"movieData":[["mov_1","MY FAIR LAD],{"1":"mov_10","2":"love actually"}],"stock":0,"success":true}

but i need json encoded data properly so that i can create an select box on movieData using(movieData.length), so for that i want json edcoded data in below format so that i can retrive successfully

{"movieData":[{"mov_1":"MY FAIR LAD,mov_10":"love actually"}],"stock":0,"success":true}

i want to know how to send an array(multidimensional/associative) and some varaibles together through json?

UPDATE

I have made my array properly and after it I'm getting json encode array below

{"movieData":{"mov_10":"love actually","mov_1":"my fair lady"},"stock":20,"success":true}

Now how to know the length of moveData? i used data.movieData.length on jquery where I'm getting these value but it returns undefined

MovieData is an object, no more an Array, so you have to visit all the properties and count them manually, something like the code below

var theLength=0;
for(var propertyName in movieData) {
    // filtering out inherited properties
    if (movieData.hasOwnProperty(propertyName)) {
        theLength++;
    }
}
// now theLength represent the length of the array

To pass more variables to the json_encode() you just need to add another level to the array you pass in, with top level sections for your different values.

If your array of movie data was in $movie_data then you'd create an array like the following:

$output_for_json = array(
  'movie_data' => $movie_data, 
  'stock' => $stock,
  'success' => $success
);

When you parse the json you will need to change the code using the data to reference the specific part of the array, like 'movie_data'
