$decoded = JWT::decode($jwt, $key, array('HS256'));

print_r($decoded);

/*
 NOTE: This will now be an object instead of an associative array. To get

 * You can add a leeway to account for when there is a clock skew times between
 * the signing and verifying servers. It is recommended that this leeway should
 * not be bigger than a few minutes.
