如何解码PHP传递的JSON字符串从android？

I want to decode json string in Php that is pass from android.

Suppose i have follwing json that comes from android
{"name":"ajay"} and in php i do

<?php
$result=json_decode('$_POST',true);
$name=$result['name'];
$response=array();
$response["message"]=$name successfully parse in php;
echo json_encode($response);
?>

This gives html tag in response.Is there is any way to solve this?

Follow this link. Maybe this will be helpful:

http://www.php.net/manual/en/function.json-decode.php

This seems working fine for me

<?php
  $result=json_decode('{"name":"ajay"} ',true);
  $name=$result['name'];
  $response=array();
  $response["message"]="$name successfully parse in php";
  echo json_encode($response);
?>

Check php manual for json_decode for more
