Edit report at https://bugs.php.net/bug.php?id=71835&edit=1 ID: 71835 Updated by: laruence@php.net Reported by: icarpenter at leadid dot com Summary: json_encode sometimes incorrectly detects recursion with JsonSerializable Status: Open Type: Bug Package: JSON related PHP Version: 7.0.4 Block user comment: N Private report: N New Comment: hmm, the problem is get_object_vars maybe return directly object->properties, which make it looks like a recursive array , Previous Comments: ------------------------------------------------------------------------ [2016-03-16 02:00:51] icarpenter at leadid dot com Description: ------------ If a class that implements JsonSerializable returns an array of get_object_vars($this) in its jsonSerialize method, and if that class is in an array that is json_encode'd, JSON_ERROR_RECURSION is returned. This does not seem to happen if jsonSerialize returns get_object_vars($this) not enclosed an array, nor does it seem to happen if the object itself is json_encode'd Test script: --------------- https://3v4l.org/OoR7D Expected result: ---------------- string(4) "[[]]" bool(false) string(6) "[[[]]]" bool(false) string(2) "[]" bool(false) string(4) "[[]]" bool(false) Actual result: -------------- string(4) "[[]]" bool(false) bool(false) bool(true) string(2) "[]" bool(false) string(4) "[[]]" bool(false) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=71835&edit=1
