PHP: how to extract ajax array response

I am getting ajax response in array format from php url. How to extract array response values in jQuery? FYI:

PHP array is:

$response = array('msg' => 'Hello', 'html' => '<b>Good bye</b>');

I am getting $response array in my ajax response. i.e.

var promo = "promo=45fdf4684sfd";
$.ajax({
    type: "POST",
    url: baseJsUrl + "/users/calc_discount",
    data: promo,
    success: function (msg) { // I am getting $response here as ajax response.
        //alert(msg);

        // Here I want to check whether response is in array format or not. if it is in array format, I want to extract msg here and want to use response array values.
    }
});

Let me know answer pls. Thanks.

and If you do not have control over the PHP output then you can use another method to get the result. Another solution is using http://phpjs.org/ library. Here you can find many functions available in JS as available in php. Usage is also same as that of PHP. So I feel if you get the json_encode/json_decode from there and use that then it can solve your problem easily.

Remember you can compile your needed functions only. In your case, it is json_encode and json_decode. No need to download whole library. Url to compile your library: http://phpjs.org/packages/configure

You should echo that $response with json_encode().

You should probably set dataType: 'json' too inside the object literal you send to $.ajax().

Then you can access it natively with JavaScript using the dot operator inside your success callback...

function(msg) {
    alert(msg.html);
}

BTW, this line...

$response = array(['msg'] => 'Hello', 'html' => '<b>Good bye</b>');

... isn't valid PHP. Remove the brackets from the first key.

I presume that you mean a JSON response, like this:

{"msg":"Hello","html":"<b>Good bye<\/b>"}

This is actually a native JS object, so you can use it right away like this:

success: function(msg){
   alert(msg.msg);
   alert(msg.html);
}

You can also use the jQuery.each() function to loop over all properties of the JSON object if you need to:

jQuery.each(msg, function(key, val) {
  alert(key + "=" + val);
});

My favorite solution for this is to encode array with PHP's function json_encode() so jquery will be happy to parse it.
