多维PHP数组到JSON数组

Question

I have this PHP Array:

Array
(
    [messages] => Array
        (
            [0] => Array
                (
                    [sender] => 17
                    [receiver] => 4
                    [message] => TEST 2
                    [timestamp] => 1367200891
                    [read] => 0
                )

            [1] => Array
                (
                    [sender] => 17
                    [receiver] => 4
                    [message] => TEST 1
                    [timestamp] => 1367197661
                    [read] => 0
                )

        )

    [new_messages] => 2
)

It gets retrieved via an Ajax Request, using json_encode() to output it in PHP.

function getMessages(rec){
var nmsg = $.ajax({
        type: "GET",
        async: true,
        url: "/ps/getUserMessages.php",
        data: {'u':rec,'s00':s00,'n01':n01,'t02':t02}       
    });
    nmsg.done(function(data) {
        var json = JSON.parse(data);
        if (typeof json.messages[0].message !== 'undefined') {
            printMessage(json);
        }
    }); 
}

And as printMessage() function, for example, i need to do something like:

loop(){
    $("#elem").append(
          '<div>Sender: '+arrayOfValues.sender+'</div>'
         +'<div>Message: '+arrayOfValues.message+'</div>'
    );
}

for each Array of values.

I tried jQuery $.each() and also for() with some examples i found, but i cannot get to work.

Something like this should work:

function printMessage(data) {
  for( var i=0; i<data.messages.length; i++ ) {
    $("#elem").append(
        '<div>Sender: ' + data.messages[i].sender + '</div>'
       +'<div>Message: ' + data.messages[i].message+ '</div>'
    );
  }
}
