Craft CMS - 如何在PHP条目查询中包含资产字段？

I am trying to figure out how to return asset field(s) in a PHP entry query. Also if I could learn how to return "custom fields" when returning an Object that would be great too! Right now I am having to specify asArray() to even get access to most of my "custom fields"

As as example: I have a Vehicle Entry which has a custom field with the handle of price (number field) and another custom field (asset field) with the handle of images. When I execute the query without specifying the asArray() param I cannot find the custom fields included in the results. But if I specify asArray() then they are all there with the exception of my images field which I think is because it is an asset field or possible because it can be a collection of images? How can I make sure all the fields tied to an entry are returned in my query?

Here are some examples of queries and the corresponding results:

PHP Query without asArray():

$entry_query = Entry::find()
->section('inventory')
->all();

Returns:

PHP Query results with asArray():

$entry_query = Entry::find()
->section('inventory')
->asArray();

Returns:

However even when specifing to make the result set an array I still cannot figure out how to include the 'images' field.

I am having a difficult time finding an answer via the documentation or an example of someone doing the same. All the examples i find are for the template side in twig.

Thanks!

This is what I ended up with:

    $vehicles = array(); // empty container to hold our modified entries
    // Lets Query our Inventory - all of it
    /** @var array $entry_query   the name of our query to get our inventory - return a list of inventory after we execute query */
    $entries = Entry::find()
        ->section('inventory')
        ->all();

    foreach($entries as $entry) {
        /*
         * Let's get all our custom fields we want
         * to include with our entries
         */
        // Get our image field and add to result set - because it's an asset field this returns a query object
        $ourimages = $entry->images->all(); // get all our images
        $price = $entry->price;
        $featured = $entry->featureThisVehicle;
        $make = $entry->make;
        $model = $entry->model;
        $year = $entry->year;
        $description = $entry->description;
        $inventoryStatus = $entry->inventoryStatus;
        $bodyStyle = $entry->bodyStyle;
        $color = $entry->color;
        $miles = $entry->miles;
        $vin = $entry->vin;
        $stkid = $entry->stkid;

        // cast out entry object as an array - so we can add props to it
        $entry = (array)$entry;

        // add our custom fields to our newly casted entry array
        $entry['images'] = $ourimages;
        $entry['price'] = $price;
        $entry['featured'] = $featured;
        $entry['make'] = $make;
        $entry['model'] = $model;
        $entry['year'] = $year;
        $entry['description'] = $description;
        $entry['inventoryStatus'] = $inventoryStatus;
        $entry['bodyStyle'] = $bodyStyle;
        $entry['color'] = $color;
        $entry['miles'] = $miles;
        $entry['vin'] = $vin;
        $entry['stkid'] = $stkid;

        // Recast back to object just cause (not really necessary since we are json_encode'ing this)
        $entry = (object)$entry;
        array_push($vehicles, $entry);
    }

    return json_encode($vehicles);
