jquery - parse json - 2 arrays

How to use each parse the json type -

retrieveMessage: function()
    {

         $.post('ActionScripts/RetrieveMessage.php',{

        }, function(data) {

            $.each(data, function(key, reader){

        alert(reader.id + reader.count); //this line does not return anyt开发者_如何学编程hing

            });

        },"json");
    }

data:

[{"id":"1","user_name":"Jenan","user_image":"ImageName","text_chat":"Hello","date":"2011-09-25 21:29:09","error":""}][{"count":"2"}]

I would get text -

id=1 count=2

PHP

$jsonresult = array();

$count = array();
$countresult = array();
$countresult["count"] = "2";
$count[] = $countresult;
while($row = mysql_fetch_array($result))
{
$thisResult = array();

$thisResult["user_auth"] = 1;
$thisResult["id"] = $row['id'];
$thisResult["user_name"] = $row['user_name'];
$thisResult["user_image"] = $row['user_image'];
$thisResult["text_chat"] = $row['text_chat'];
$thisResult["date"] = $row['date'];
$thisResult["error"] = "";

$jsonresult[] = $thisResult;
}
  echo json_encode($jsonresult) . json_encode($count);

Here compose two collections together. How to read the collection with id parameters and collection of the count? Is this the right solution? What solution do I choose for composing arrays?

Thanks for the advice.

Instead of gluing 2 arrays together:

echo json_encode($jsonresult) . json_encode($count);

you should make one array that contains them:

echo json_encode(array(
   'result' => $jsonresult,
   'count' => $count
));

Now in your JavaScript:

$.post('ActionScripts/RetrieveMessage.php', {}, function(data) {
    var result = data.result;
    var count = data.count;

    $.each(result, function(k,v){
       alert(v.id+' '+count[k].count); // 1 2
    });
},"json");

try

 }, function(data) {
       data = eval(data);
       $.each(data, function(key, reader){
