So the bug is even older, when you use (array) instead of
get_object_vars() :-(
Sound like an opportunity to fix it in PHP7 which suppose to have better types. ;-)
I've found some workarounds make the following code work reliably across php versions:
$data["200"] = false;
Workaround 1:
$data = unserialize(serialize((array) $object));
Workaround 2:
$data = unserialize(serialize(get_object_vars($object)));
Workaround 3:
$data = json_decode(json_encode($object), true);

that is get_object_vars now reuse the same array of the properties table of stdclass..
like:
<?php
$object = json_decode('{"200": true}');
$data = (array)($object);
var_dump($data);
$data['200'] = false;
var_dump($data);
echo json_encode($data, JSON_PRETTY_PRINT);
this will result the same result both on php-5.6 and php7

@laruence But the code snippet doesn't use integers anywhere, but php7 somehow decides to use
the integer 200 instead of the given '200'.
PHP 5.3, 5.3, 5.4, 5.5, 5.6 doesn't have this issue.

actually, this is not something new...
because, there are string "200" and interge 200 in the same array.
which is an knew issue.

Reproduced even with 5.5.
Thanks.
