Ben böyle bir array in Javascript, yapı istiyor

        $(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:
