Bug #81629 [Opn]: Error casting object to array

Edit report at https://bugs.php.net/bug.php?id=81629&edit=1 ID: 81629 Updated by: cmb@php.net Reported by: newed2008 at gmail dot com Summary: Error casting object to array Status: Open Type: Bug -Package: *General Issues +Package: Scripting Engine problem PHP Version: 7.4.25 -Assigned To: +Assigned To: nikic Block user comment: N Private report: N New Comment: This might actually be by design. After all, casting object to array doesn't follow the usual access rules (e.g. private properties are contained in the array as well). If so, this would be a documentation issue. Nikita, could you please clarify? Previous Comments: ------------------------------------------------------------------------ [2021-11-17 08:37:34] newed2008 at gmail dot com Description: ------------ Following the strong typing in the class description, I expect that when casting an object to an array, the array will match the described types or throw an exception. In this example, I also have a property ($typeString) that cannot be null. I skipped the initialization of this property in the code and expected that when I tried to transform such an object to an array, I would get an exception like Typed property ... must not be accessed before initialization, as if I access an uninitialized property. I think if the property is in a typed class, then casting to an array should take into account typing. Test script: --------------- class A { public int $typeNumber; public string $typeString; } $a = new A(); $a->typeNumber = 1; var_dump( (array)$a ); Expected result: ---------------- Uncaught Error: Typed property A::$typeString must not be accessed before initialization Actual result: -------------- array(1) { ["typeNumber"]=> int(1) } ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=81629&edit=1
