ID: 62977 Updated by: cataphr...@php.net Reported by: ladislav at marek dot su Summary: array_unique() misbehaves with array of DateTimes Status: Assigned Type: Bug Package: Class/Object related Operating System: Linux PHP Version: 5.4Git-2012-08-30 (Git) Assigned To: laruence Block user comment: N Private report: N New Comment: laruuence: The patch is very strange. Why are making all the elements of the same class being compared equal? Objects can be compared. Perhaps you should fix the DateTime's compare_objects() object handler.
