As you can read in PHP Manual $_POST, $_POST contains values in associative array. As in manaul too, it is :

An associative array of variables passed to the current script via the HTTP POST method.

So if you are sending any json string from client-end in any variable, Use that variable to read that json string like this.

$var = json_decode($_POST['emaildata'],true);
echo json_encode($var["email"]);

Please check, if it works for you..

If I got you correctly and your posting a json string you can do:

$requestBody = @file_get_contents('php://input');
$var = json_decode($requestBody, true);
echo json_encode($var['email']);
