Missing json array in post request to php

Question

I'm trying to send json object from Android device to PHP to insert it to database, but server can't find it. What I did wrong? Thanks.

Script fails in isset check.

PHP Script:

    <?php

$json_array = json_decode($_POST['messages']) -> messages;

if(isset($json_array))
{
    //connect to database and do insertions.
} else
{
    echo "Not found array with messages in POST request\n";
}

Post request contains:

{"messages":[{"message":"Hello. Test from ukraine","id":1,"from_sender":"1111-111-1111","box":"2","type":"sms"}]}

And it's formed like this:

HttpClient httpClient = new DefaultHttpClient();

            try {
                HttpPost httpPost = new HttpPost(BASE_URL + "/josyko.php");
                List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
                nameValuePairs.add(new BasicNameValuePair("messages", request.toString()));
                httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

                HttpResponse httpResponse = httpClient.execute(httpPost);
                result = EntityUtils.toString(httpResponse.getEntity());
            } catch (IOException e) {
                e.printStackTrace();
            }

var_dump($_POST, $json_array);

You can use: http://php.net/manual/en/reserved.variables.httprawpostdata.php

$json_array = json_decode($HTTP_RAW_POST_DATA) -> messages;

Or a better solution:

file_get_contents('php://input'); // instead of $HTTP_RAW_POST_DATA

Do not use $HTTP_RAW_POST_DATA. PHP Manual says, “the preferred method for accessing the raw POST data is php://input”.

On my local machine and webhosting it's working with $_POST, but on other hosting it's not working... I don't think that the problem is in $HTTP_RAW_POST_DATA...
