How to handle json data, which I send via ajax request, in php script?

Question

I am sending some json data with ajax:

function send() {
    $.ajax({
        url: '/index.php?action=setShopOrdersGoods&order_id='+orderId,
        type: 'post',
        dataType: 'json',
        success: function (data) {
            $('#target').html(data.msg);
        },
        data: JSON.stringify(goods)
    });
}

There are no problems with it. Firebug console screen:

Soajax request is sending okay. Now I need to handle it.

How I can do this?

echo __FILE__;
echo '<pre>';
var_dump($_POST);
echo '</pre>';
exit;

This code shows nothing. Looks like there are no data send via post. Firebug response tab of sent ajax request:

enter image description here

How I can handle json data in php file then?

how do you evaluate that your php shows nothing? If you just open the path to it it surely will show nothing since it needs a post request for that. Are you aware of that? You browser tools can show you the servers response for whem you send data via ajax. Try that. — Andresch Serj

@DS9 If dumping $_POST shows nothing, it is very unlikely that $_POST['items'] will show something right? — Andresch Serj

I updated my question - added response - result of php code above. — Sharikov Vladislav

your response tab shows ajax.php but you use index.php in your json. this doesn't seem right — Andresch Serj

Json data does not receive in post.

$json = file_get_contents('php://input');
$post = json_decode($json, TRUE);

echo __FILE__;
echo '<pre>';
var_dump($post);
echo '</pre>';
exit;

Wow. I did not know that. How did i not know that? Frameworks! They take all the work out of your hands and leave you clueless :-D

@AndreschSerj I am not using framework. Simple logic. The question was not about how I handle ajax request etc. I asked why I am getting nothing when var_dump($_POST) and author of this answer helped me.
