Php pass array to Javascript

Question

I want an array in Javascript, structure like this

        $(function()
    {
        // prepare the data
        for (var i=0; i<50000; i++) {
            var d = (data[i] = {});

            d["id"] = "id_" + i;
            d["num"] = i;
            d["title"] = "Task " + i;
            d["duration"] = "5 days";
        }

I want this array to be created through php. I already have the array there created by for loop

EDITED:

Is the above data in Javascript a multidimensional array, a simple array or a var?

is the structure saved in "d" or in data[i][id],data[i][title],... ?

Answer 1

ie, $data = array('item' => 'description', 'item2' => 'description2');

json_encode($data);

All you need

Answer 2

Use json_encode() to encode the array.

Access PHP variable in JavaScript That example works with arrays, too.
