If you just want to be able to access the data in object notation, I'd
simply do this:
$obj = new ArrayObject($data, ArrayObject::ARRAY_AS_PROPS);
You will then be able to access anything that was put into $data as a
property of that object:
$obj->prop_one, $obj->prop_two, and so on.
If your goal is to have a row object that can be persisted to the
database, then you should be using createRow().
The __construct() of a Zend_Db_Table_Row object doesnt actually take
just data, it also takes stateful information like whether or not the
data is already in the database already, and if it should be read-only,
but most importantly, which table object it should be referenced from.
On your row object below, calling $row->save() should throw an
exception, b/c it will not know which table object to attempt to use to
do the implied insert() or update().
The other problem that might arise with injecting into the row object
yourself is that your row object does not know what is a valid row and
what is not. This type of stuff is typically handled in the createRow()
routine of the Table object, explore that here:
http://framework.zend.com/svn/framework/standard/trunk/library/Zend/Db/Table/Abstract.php
(search for createRow())
So, in summary, if you are only concerned with arrayObject access, see
the above. If you are concerned with modeling new data into a live row
object, you should probably stick with createRow(), or try to mimic what
is going on inside createRow() as best as possible.
