通过Ajax发布发送JavaScript多维数组

Question

I have a multi-dimensional array like below

var myarray = new Array();
myarray["firstkey"] = new Array();
myarray["firstkey"]["secondkey"] = new Array();
myarray["firstkey"]["secondkey"]["0"] = new Array();
myarray["firstkey"]["secondkey"]["0"]["a"] = 100;
myarray["firstkey"]["secondkey"]["0"]["b"] = 1200;
myarray["firstkey"]["secondkey"]["0"]["c"] = 32000;
myarray["firstkey"]["secondkey"]["0"]["d"] = 23001;
myarray["firstkey"]["secondkey"]["0"]["e"] = "text";
myarray["firstkey"]["secondkey"]["0"]["f"] = "text";
myarray["firstkey"]["secondkey"]["0"]["g"] = "text";
myarray["firstkey"]["secondkey"]["0"]["h"] = "";
myarray["firstkey"]["secondkey"]["0"]["i"] = 0;
myarray["firstkey"]["secondkey"]["0"]["aa"] = new Array();
myarray["firstkey"]["secondkey"]["0"]["bb"]["bbb"] = 16;
myarray["firstkey"]["secondkey"]["0"]["cc"]["ccc"] = "text";
myarray["firstkey"]["secondkey"]["0"]["dd"]["ddd"] = new Array();
myarray["firstkey"]["secondkey"]["0"]["ee"]["eee"]["0"] = "text";
myarray["firstkey"]["secondkey"]["0"]["ff"]["fff"]["1"] = "text";`

and I want to get it from PHP, but I can't find solution. Can anybody please tell me the solution. The response would be highly appreciated.

Answer 1

Maybe you can try sending JSON?

You should read it from PHP with:

$json = file_get_contents("php://input");

Answer 2

You could do AJAX

The JavaScript:

var array = JSON.stringify(myarray);
$.ajax({
    url: "/myphp/file.php",
    data: {array: array},
    dataType: "json",
    success: function(data){
        alert(data["return"]);
    }
});

The PHP:

$array = json_decode($_POST["array"]);
$savedVal = $array["firstkey"]["secondkey"]["0"]["a"];
echo json_encode(array("return" => $savedVal));
