php to json structure

Question

I am having a hard time transferring my php array of arrays to a json object.

Array(
    [28] => Array(
        [0] => Array(
            [0] => 1
            [1] => 5
        ) 
        [1] => Array(
            [0] => 1 
            [1] => 18
        )
        [424] => Array(
            [0] => Array(
                [0] => 1
                [1] => 5
            ) 
            [1] => Array(
                [0] => 1
                [1] => 18
            )
        )
     )
)

After I json_encode this structure in jQuery I use the .each and get the two arrays but I cant seem to grab the [28] and [424]. Any thoughts?

$.each(data, function(i, val) {
    console.log(val); // NAME ??
    console.log(data[i][0]); // LIST 1
    console.log(data[i][1]); // LIST 2
});

What does console.log(i) yield?

$.each(data, function(i, val) {
    console.log(i); // name
    console.log(val); //array
});

JSON encodes keys as strings, which means that jQuery is looking for a string, not an integer. Try accessing the arrays using strings.

json_encode (no flags given) will encode the array keys as object member names, not array keys.

Try this

$.each(data, function(i, val) {
    //First iterration "this" will point to '28' array
    //Second iterration "this" will point to '424' array

    //You can use it like this, this[i][0]

});

The PHP array keys 28 and 424 will be represented in the javascript variable i inside the callback function.

Check the docs for $.each ^Docs, they explain it in detail.

Easy enough, the examples used 'i' and I assumed it was an integer all the time. Thanks!
