Bug #46600 [NoF]: "_empty_" key in objects (see #41504)

Edit report at https://bugs.php.net/bug.php?id=46600&edit=1 ID: 46600 Updated by: ajf@php.net Reported by: Matt at mpcm dot com Summary: "_empty_" key in objects (see #41504) Status: No Feedback Type: Bug Package: JSON related Operating System: * PHP Version: 5CVS, 6CVS (2008-11-18) Block user comment: N Private report: N New Comment: This is arguably not a bug since you can't have objects with empty property names, so this is necessary to allow decoding JSON objects with empty keys. However, that's a rather arbitrary restriction. If we removed it, we could fix this.
