Receiving JSONObject in PHP - php

Question

I am sending JSONObject to the server using below code. But I am unable to receive it in server side using PHP . Can anyone please guide me how to receive it.
public void sendStatus(JSONObject object) {
HttpParams myParams = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(myParams, 10000);
HttpConnectionParams.setSoTimeout(myParams, 10000);
HttpClient httpclient = new DefaultHttpClient(myParams);
String jsonString = object.toString();
try {
HttpPost httppost = new HttpPost(url);
httppost.setHeader("Content-type", "application/json");
StringEntity se = new StringEntity(jsonString);
se.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));
httppost.setEntity(se);
HttpResponse response = httpclient.execute(httppost);
String temp = EntityUtils.toString(response.getEntity());
} catch (ClientProtocolException e) {
} catch (IOException e) {
}
}
I have already done it using name value pair using following code
$datastring = trim($headers['name']);
But as in the above code I am only getting the JSONObject but not any tag. So please anyone can help me or provide me any useful link then I will be grateful.
My JSONObject format is as belos=w
{
"user_id": "123456",
"Objects": [
{
"name": "AAA"
},
{
"name": "BBB"
},
{
"name": "CCC"
},
{
"name": "DDD"
}
]
}

To send the JSON as string from the Android device you can send it as a POST param:
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("json_string", jsonString));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
or if you want to send it as a header:
httppost.addHeader("json_string", jsonString)
However, a header has a maximum length so I'd recommend sending it as POST params
In order to work with a JSON object in PHP, you must decode it first into a associative array doing the following
$jsonAsArray = json_decode($jsonAsString, true)
Afterward, you'll be able to access JSON properties like:
$jsonAsArray['user_id'] // 123456
$jsonAsArray['Objects'][1]['name'] // BBB
