ReflectionObject::getProperties() returns property which added to ArrayObject with offsetSet(), but this property can't be gotten by ReflectionProperty::getValue().


Test script:

class A extends \ArrayObject {}

$a = new A;
$a->offsetSet('test', 'testValue');

$reflection = new \ReflectionObject($a);
$properties = $reflection->getProperties();

$c = count($properties);

echo $c . PHP_EOL;

if ($c) {
    echo $properties[0]->getValue($a) . PHP_EOL;

Expected result:
I'm not sure what is expected behaviour, but it's strange to have abiliti get property of ArrayObject and have not ability to get value of this property.

1. Properties have not be returned by ReflectionObject::getProperties()
------ EXPECTED -----
------ EXPECTED -----

2. Property values should be accessible by ReflectionProperty::getValue()
------ EXPECTED -----
------ EXPECTED -----

Actual result:

Notice: Undefined property: A::$test in /in/FbMbQ on line 14

Indeed, the notice is caused by commit a1ed4ab3[1]. However, the behavior didn't make sense before that commit, because the property's value was returned as NULL[2]. It seems to me that ::getProperties() should return 0 (as done by HHVM).

This has been fixed in PHP 7.4: ArrayObject no longer reports the array contents as properties to reflection.
