PHP MongoDB - 将数组保留为数组而不是对象

Question

This is the object which I inserted to mongodb.

{
    '_array': [1,2,3],
    '_ass_array': [{'num': 1, 'name': 'One'}], 
    '_obj': {'key': 'val'}
}

If I query on terminal, I can get the same as I inserted. But while querying via PHP's MongoCollection::findOne()/ MongoCollection::find(), I am getting following format.

{
    '_array': { 0: 1, 1: 2, 2: 3},
    '_ass_array': {
       0: {'num': 1, 'name': 'One'}
     }, 
    '_obj': {'key': 'val'}
}

Is there any way I can get the array as array and object as object? if required, I can update the question with the complete code.

On the same data this works for me. Just wondering if you are doing something different in a serialization since the JSON syntax in the post. As expected $data is a PHP array.

<?php

$dbhost = 'localhost';
$dbname = 'test';

$m = new Mongo("mongodb://$dbhost");
$db = $m->$dbname;

$col = $db->data;

$data = $col->findOne();

echo json_encode( $data ) . "
";

?>

A little intrigued how you arrived at your result, as various people here have that format in their MongoDB documents.
