PHP Object, set multiple properties

Is it possible to set multiple properties at a time for an object in php? Instead of doing:

$object->prop1 = $something;
$object->prop2 = $otherthing;
$object->prop3 = $morethings;

do something like:

$object = (object) array(
    'prop1' => $something,
    'prop2' => $otherthing,
    'prop3' => $morethings
);

but without overwriting the object.
