 New Comment:

I don't agree that this is a problem of the JSON documentation in
the PHP manual, because it documents the ext/json extension, and
not other alternative implementations (one can even think of JSON
replacements written in userland).

Of course, it seems to be reasonable that alternative
implementations point out differences. However, that is already
done in README.md of the pecl-json-c[1]:

| json_decode use the json-c library and is mostly compatible.
|
| * > 64 bits integer are always parsed as integer (never float or
|   string)

Please file bugs related to json-c (including its PECL page) to
<https://github.com/remicollet/pecl-json-c/issues>, as requested
by the package maintainer.

I would suggest this remain open because it is as much a bug in jsonc as it is 
a bug of the PHP docs - example 5 MUST be rectified.

Fair, but until it is, this disparity should be noted in the PHP docs and using 
it as a drop-in replacement should be discouraged because there is no 
feature-for-feature parity. It just doesn't work as documented, simple as that.

Actually, the package should be "jsonc", but unfortunately that is
not available from the list, so I've changed to "PECL".

Anyhow, it seems that JSON_BIGINT_AS_STRING is not (yet) fully
implemented:
<https://github.com/remicollet/pecl-json-c/commit/5822493892c65219db07378f22bb3b1ccb5fdd06>.

Description:

>From manual page: http://www.php.net/function.json-decode
---

In example #5, BIGINT is converted to string using the JSON_BIGINT_AS_STRING 
flag. However, when using Remi's pecl extension (the drop in replacement), this 
will fail and report an integer overflow notice for numbers larger than signed 
max integer (like the one in the json_decode documents).

Obviously, this is an edge case, but it still *can* and *does* affect some 
implementations - the API of the company I'm building a lib for sometimes 
returns unsigned 64bit integers, and thus this will break. Since we're dealing 
with JSON, the notice headers will break things and make my app unusable unless 
I use the silence operator(@).

More details here:

Test script:
---------------
<?php

var_dump(json_decode('{"number": 12345678901234567890}', false, 512, 
JSON_BIGINT_AS_STRING));

Expected result:
----------------
object(stdClass)#1 (1) {
  ["number"]=>
  string(20) "12345678901234567890"
}

Actual result:
