json_encode not working with a html string as value

Question

I am debugging this ajax for quite a time now. I have this on my jQUery file:

$(\"#typeForm\").ajaxForm({
    success : function(html){
        alert(html);

Some stuff to try:

ajaxForm supports dataType argument, if you expect a JSON coming from the server, use dataType: json like so

$("#typeForm").ajaxForm({
    success : function(html){
       // html here is already automatically a json object
       alert(html.prompt);
    },
    dataType: 'json'
}).submit();

Could you post the full service.php? OR try the following:

exit(json_encode(array('file_name' => $data['upload_data']['file_name'], 'prompt' => $str)));

-- EDIT --

Not sure why json_encode returns such weird string :s, is the json_encode a standard php library or an external library? I'm asking this because some servers don't have json_encode in their php installation... I tested on my local and using php internal json_encode and it works fine:
