Edit report at https://bugs.php.net/bug.php?id=75393&edit=1 ID: 75393 Updated by: bwoebi@php.net Reported by: bwoebi@php.net -Summary: Crash when assign-adding an array to an object +Summary: Value not preserved when assign-adding an array to an object Status: Open Type: Bug -Package: Reproducible crash +Package: Scripting Engine problem Operating System: Irrelevant PHP Version: 7.0Git-2017-10-16 (Git) Block user comment: N Private report: N New Comment: Similarly: php -r 'set_error_handler(function() { throw new \Exception; }); $a = "2"; $a .= "a"; try { $a+=1; } catch (\Exception $e) { } var_dump($a);' int(3) (instead of string(2) "2a") (turns out the crash has already been fixed in the most recent git, but not yet in the last release. - renaming thus.) Previous Comments: ------------------------------------------------------------------------ [2017-10-17 10:36:31] laruence@php.net of course I also understand why it should be an stdclass instance, it also make sense, but it will make the codes complex, and this is really a rarely wrong case, so I think choose the easy way is a good chioce here. ------------------------------------------------------------------------ [2017-10-17 10:34:08] laruence@php.net why not? <?php $o = new Stdclass(); var_dump((int)$o); output: PHP Notice: Object of class stdClass could not be converted to int in /tmp/1.php on line 3 int(1) and for: $o += [] we preparing operands first, then trying to do add, then result in unsupported operand, which seems reasonable to me ------------------------------------------------------------------------ [2017-10-17 10:15:32] bwoebi@php.net @laruence: It doesn't crash with master, yes. But it still does with PHP 7.0 and 7.1. Also $o must not be int(1), but must be an instanceof stdClass afterwards. ------------------------------------------------------------------------ [2017-10-17 03:53:50] laruence@php.net this seems already be fixed: https://3v4l.org/oF3Al ------------------------------------------------------------------------ [2017-10-17 03:49:13] laruence@php.net I can not reproduce this.... ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
