Convert JSON to Array with 'json_decode'
then use 'array_append' to add new data then 'json_encode' it again.

<?php
$json = '{"a":1,"b":2,"c":3,"d":4,"e":5}';
$array = (array) json_decode($json);

$append = array(
    'username' => array('alias' => 'somename', 'realname' => 'stacky');
    'password' => 'somepass';
);

$combined = array_merge($array, $append);
$encoded = json_encode($combined);

print_r($encoded);
?>
