Add properties to stdClass object from another object

Asked 2010-04-16T11:55:10.967

I would like to be able to do the following:

$obj = new stdClass;
$obj->status = "success";

$obj2 = new stdClass;
$obj2->message = "OK";

How can I extend $obj so that it contains the properties of $obj2, eg:

$obj->status //"success"

$obj->message // "OK"

I know I could use an array, add all properties to the array and then cast that back to object, but is there a more elegant way, something like this:

extend($obj, $obj2); //adds all properties from $obj2 to $obj

You could use get_object_vars() on one of the stdClass object, iterate through those, and add them to the other:

function extend($obj, $obj2) {
    $vars = get_object_vars($obj2);
    foreach ($vars as $var => $value) {
        $obj->$var = $value;
    }
    return $obj;
}

Not sure if you'd deem that more elegant, mind you.

Edit: If you're not stingy about actually storing them in the same place, take a look at this answer to a very similar question.
