Test script: --------------- class A { private string $prop1 = '123'; public function __toString() { return $this->prop1; } } class B { private string $prop2; } $b = new B(); $reflector = new ReflectionClass($b); $property = $reflector->getProperty('prop2'); $property->setAccessible(true); $property->setValue($b, new A()); Expected result: ---------------- Property B::prop2 must have value '123'. No errors must happen. Actual result: -------------- PHP Fatal error: Uncaught Error: Cannot access private property A::$prop1 in test.php:9 Stack trace: #0 [internal function]: A->__toString() #1 test.php(23): ReflectionProperty->setValue() #2 {main} thrown in /home/sergey/www/twin.client/test.php on line 9 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=79683&edit=1
