Unserialization throwing exceptions is completely normal. You get a fatal error because you did not catch the exception. ------------------------------------------------------------------------ [2020-07-22 14:16:45] isharafa at unb dot ca When I modify the datetime object, it just return false, but with this specific test case I get the Fatal Error. That's why I reported this bug. ------------------------------------------------------------------------ [2020-07-22 12:26:49] cmb@php.net So this is obviously not a bug. ------------------------------------------------------------------------ [2020-07-22 10:59:42] isharafa at unb dot ca Yes. ------------------------------------------------------------------------ [2020-07-21 23:39:21] requinix@php.net What's the bug? You're crafting a custom serialized string (which is already a bad thing) containing an invalid date string that DateTime would have rejected (so the object shouldn't even exist in the first place) and when you try to unserialize it you get an exception (as opposed to a crash). ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
