Bug #53963 [Opn->Ver]: Failed to decode, yet json_last_error() is JSON_ERROR_NONE

Edit report at http://bugs.php.net/bug.php?id=53963&edit=1 ID: 53963 Updated by: aharvey@php.net Reported by: hm2k@php.net Summary: Failed to decode, yet json_last_error() is JSON_ERROR_NONE -Status: Open +Status: Verified Type: Bug Package: JSON related PHP Version: 5.3.5 Block user comment: N Private report: N New Comment: Here's a much simpler test case based on the munged JSON from atsearch.autotrader.co.uk: <?php $input = '{"searchform":null}, null, {"searchresults":"foo"}'; var_dump(json_decode($input)); var_dump(json_last_error()); ?> Obviously json_last_error() should return something other than 0, presumably JSON_ERROR_SYNTAX (4), since it's not syntactically valid JSON. Previous Comments: ------------------------------------------------------------------------ [2011-02-08 20:23:48] hm2k@php.net Description: ------------ I'm trying the json_decode() function on real world strings, not just from strings produced using json_encode(). I have included the test case from bug #52262 as well to show that this issue is different. Thanks.
