PDO statement execute enhancement

I have a suggestion that is related a little to my bug report #38394 ( http://bugs.php.net/bug.php?id=38394). It's about the execution of a prepared statement. Let's say we have a prepared statement for UPDATE table SET field1 = :field1, field2 = :field3 WHERE id = :id in order to execute it we have something like this: $data = array ('id' => 3, 'field1' => 'value1', 'field2' => 'value2'); $stmt->execute ($data); But I think that it is so common to have things like this $data = array ('id' => 3, 'field1' => 'value1', 'field2' => 'value2', 'field3' => 'value3', 'field4' => 'value4'); $stmt->execute ($data); But that is not executed because we have some additional key/value pairs. So the idea is to allow this. Also I suggest we allow using object along with an array. This is a common situation also. But I have to ask you about the C implementation because it may need a lot of rewriting about this but if it is easy, it think it may be good to be done.
