Bug #78411 [Fbk->Dup]: Typed properties not working as expected when instantiated via reflection.

Edit report at https://bugs.php.net/bug.php?id=78411&edit=1 ID: 78411 Updated by: nikic@php.net Reported by: tandrewbennett at hotmail dot com Summary: Typed properties not working as expected when instantiated via reflection. -Status: Feedback +Status: Duplicate Type: Bug Package: *General Issues Operating System: Ubuntu 16.04 PHP Version: 7.4.0beta2 Block user comment: N Private report: N New Comment: Yeah, the __set() behavior is a known issue, unclear what we should do about that. Marking this as a duplicate of bug #78226. Previous Comments: ------------------------------------------------------------------------ [2019-08-13 20:48:58] tandrewbennett at hotmail dot com I'm sorry Nikita. I copied and pasted the example script from an entity that I created when testing in a real world app. I just read through the RFC (trying t figure out what's causing this) and realized that uninitialized typed properties are being passed through __SET() when assigning values to them (even when assigned from within an instance method inside the class)? I didn't realize this was the case (my base entity class makes use of the __SET() method) and that seems to be what was causing this). I'm sorry for the confusion, I didn't expect __SET() to be invoked when I was assigning properties from within the scope of the class itself (not from the outside). ------------------------------------------------------------------------ [2019-08-13 20:25:24] nikic@php.net Can't reproduce: https://3v4l.org/U8t8M Same result on current 7.4 HEAD. ------------------------------------------------------------------------ [2019-08-13 20:15:49] tandrewbennett at hotmail dot com Description: ------------ When instantiating an object using reflectionClass::newInstanceWithoutConstructor, assigning values to uninitialized typed properties has no effect. Test script: --------------- class Foo { protected string $bar; protected string $baz; protected string $qux = 'initial qux'; public function fillValues() { $this->bar = 'bar'; $this->baz = 'baz'; $this->qux = 'qux'; } public function getBar() { return $this->bar; } public function getBaz() { return $this->baz; } public function getQux() { return $this->qux; } } $rc = new ReflectionClass(Foo); $foo = $rc->newInstanceWithoutConstructor(); $foo->fillValues(); echo $foo->getBar() . PHP_EOL; echo $foo->getBaz() . PHP_EOL; echo $foo->getQux() . PHP_EOL; Expected result: ---------------- bar baz qux Actual result: -------------- Fatal error: Uncaught Error: Typed property Foo::$bar must not be accessed before initialization ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=78411&edit=1
