From manual page: https://php.net/class.arrayobject

When My class inherits the ArrayOsbject class of PHP, the parameters I need to pass are inconsistent with the PHP Arrayobject document. I think the document should be updated.

Test script:
---------------
In PHP 7,it is normal.As follows:
<?php
class MyArrayObject extends ArrayObject
{
    public function asort()
    {
//        parent::asort(); // TODO: Change the autogenerated stub
    }

    public function ksort()
    {
//        parent::ksort(); // TODO: Change the autogenerated stub
    }
}
?>

In PHP 8,there was a fatal error.
<?php
class MyArrayObject extends ArrayObject
{
    public function asort()
    {
//        parent::asort(); // TODO: Change the autogenerated stub
    }

    public function ksort()
    {
//        parent::ksort(); // TODO: Change the autogenerated stub
    }
}
?>
Run it In PHP 8,it happens a PHP Fatal error.As follows:

PHP Fatal error:  Declaration of MyArrayObject::asort() must be compatible with ArrayObject::asort(int $flags = SORT_REGULAR) in MyArrayObject_In_PHP8.php on line 13

Fatal error: Declaration of MyArrayObject::asort() must be compatible with ArrayObject::asort(int $flags = SORT_REGULAR) in MyArrayObject_In_PHP8.php on line 13

Expected result:
----------------
