When reflecting on some native PHP class constructs, the names of the parameters do not match up to the names of the variables in the PHP docs. It also seems as if the type-hint in the docs of the DateTime constructor are missing when using the ReflectionParameter::getClass() method.

Test script:
---------------

$reflector = new ReflectionClass('DateTime');
$constructor = $reflector->getConstructor();

if ($constructorParams = $constructor->getParameters()) {
    foreach ($constructorParams as $i => $param) {
        $name = $param->getClass() ? $param->getClass()->name : $param->name;

        var_dump($name);
    }
}

$reflector = new ReflectionClass('ArrayObject');
$constructor = $reflector->getConstructor();

if ($constructorParams = $constructor->getParameters()) {
    foreach ($constructorParams as $i => $param) {
        $name = $param->getClass() ? $param->getClass()->name : $param->name;

        var_dump($name);
    }
}



Expected result:
----------------
DateTime: According to the docs, the names of the parameters should be "time" and "timezone". The type-hints are also missing, for example "timezone" is a "DateTimeZone".

ArrayObject: According to the docs, the names of the parameters should be "input", "flags", and "iterator_class".

Actual result:
--------------
DateTime: Names of the parameters are "time" and "object", with no type-hints.
ArrayObject: Names of the parameters are "input", "ar_flags", and "iterator_class"
