Answer 1

<?php
    $a = $_POST[data];
    $b = json_decode($a);
    $c = $b['Name'] . " beta";
    header('Content-Type: application/json');
    echo json_encode($c);
?>

Answer 2

The "." notation is not used in PHP to access / set properties - more like Javascript and you need to have quotes around the $_POST variable ~ unless data is defined as a constant. I think you could try something like this though.

<?php
    $b = json_decode( $_POST['data'],true );
    $b['name'].='beta';
    echo json_encode($b);
?>
