无法在php中的_POST变量中获取JSON数据

Question

I'm using this curl command to send json data to a php webservice, but i'm not getting anything in the $_POST variable.

Here is the curl command

 curl -X POST -i -H "Content-type: application/json" -c cookies.txt -X POST http://192.168.2.127:8888/json.php -d '{"age":"234","password":"password"}'

and here is the php code.

<?php
header('Content-type: application/json');

var_dump($_POST);
$return_arr = array();
$age = $_POST['age'];
$ageInt = intval($_POST['age']);
$return_arr['age1'] = $age;
var_dump($_POST);
$return_arr['age2'] = $ageInt;
echo json_encode($return_arr);
?> 

Thanks in advance

Once try this

curl -X POST -H "Content-Type: application/json" -d  '{"age":"21343","password":"password"}' http://192.168.2.127:8888/json.php
