dojo.data expects a format like the following:
{
identifier: "name",
items: []
}
The "items" parameter needs to be an array of items. Each item in that
array should be an associative array. In your example below, $testArr is
a *single* item to send. You would then provide it to Zend_Dojo_Data as
this:
$data = new Zend_Dojo_Data('id', array($testArr), 'description');
(I'm assuming that 'description' would be the field displayed, and thus
it corresponds to the 'label' in a dojo.data payload.)
Typically you'll send more than a single item back, in which case you
should send an array of such items, or some iterable object of items.
