@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.

Description:
------------
Reading and writing to an array could lead to new array entries (with an integer key) instead of
overwriting the value.
This even leads weird json output using which uses same key twice, but that's an other issue.
Test script:
---------------
$object = json_decode('{"200": true}');
$data = get_object_vars($object);
$data['200'] = false;
echo json_encode($data, JSON_PRETTY_PRINT);
Expected result:
----------------
{
"200": false
}
Actual result:
--------------
{
"200": true,
"200": false
}
