JSON Post data empty - Linux curl Command

Question

I am trying to post json data to php file using linux curl command, (Lamp Server)

$ curl -V -H "Content-Type: application/json" -X POST -d '{"id": "123"}' 
       http://localhost/crm/UpdateUser.php

In UpdateUser.php,

<?php echo var_dump ($_POST);?>

OUTPUT:

[ec2-user@ip-10-35-1-181 ~]$ curl -v -H "Content-Type: application/json" -X POST -d '{"id": "123"}' http://viacrm.odema.net/crm/UpdateUser.php

$_POST only contains the results of decoding an application/x-www-form-urlencoded request. You need to read the raw request body. If you have the always_populate_raw_post_data configuration directive turned on, then the raw body will be in $HTTP_RAW_POST_DATA; otherwise you can obtain it by reading from the php://input stream.

Instead of $_POST try it:

<?php
    print($HTTP_RAW_POST_DATA);
?>
