在PHP中使用公共密钥合并数组

I'm merging a couple of arrays like this in PHP

//all the other stuff
$array1 = (array) $new;
$array2 =  (array) $info;
$ab = array('a' => $array1, 'b' => $array2);
print_r($ab);

print_r($ab) gives me something like this:

Array
(
    [a] => Array
        (
            [entries] => Array
                (
                    [0] => stdClass Object
                        (
                            [title] => Serial - This American Life
                            [id] => Serial is a podcast from the creators of This American Life, hosted by Sarah Koenig. 
                        )

                    [1] => stdClass Object
                        (
                            [title] => This American Life - This American Life
                            [id] => This American Life is a weekly public radio show, heard by 2.2 million people on more than 500 stations. 
                        )

                    [2] => stdClass Object
                        (
                            [title] => Real Crime Profile - Real Crime Profile
                            [id] => Podcast talking about criminal cases and personality profiling.
                        )

                )

        )

    [b] => Array
        (
            [entries] => Array
                (
                    [0] => stdClass Object
                        (
                            [artistName] => This American Life

                        )

                    [1] => stdClass Object
                        (
                            [artistName] => This American Life

                        )

                    [2] => stdClass Object
                        (
                            [artistName] => Real Crime Profile

                        )

                )

        )

)

This is close to what I'm looking for, but ideally, I'd like to simplify this even more so I don't have an a and b "tree" within this array.

This is what I'm trying to end up with:

Array
(
    [a] => Array
        (
            [entries] => Array
                (
                    [0] => stdClass Object
                        (
                            [title] => Serial - This American Life
                            [id] => Serial is a podcast from the creators of This American Life, hosted by Sarah Koenig. 
                            [artistName] => This American Life
                            [feedUrl] => http://feeds.serialpodcast.org/serialpodcast
                            [primaryGenreName] => News & Politics
                            [artworkUrl60] => http://is2.mzstatic.com/image/thumb/Music69/v4/70/c9/71/70c97133-f3a8-738e-ea2c-27a6dc7d9731/source/60x60bb.jpg
                        )

                    [1] => stdClass Object
                        (
                            [title] => This American Life - This American Life
                            [id] => This American Life is a weekly public radio show, heard by 2.2 million people on more than 500 stations.
                            [artistName] => This American Life
                            [feedUrl] => http://feed.thisamericanlife.org/talpodcast
                            [primaryGenreName] => Personal Journals
                            [artworkUrl60] => http://is5.mzstatic.com/image/thumb/Music4/v4/1f/b8/0f/1fb80f69-bd94-8cad-0a2f-b082541d5f64/source/60x60bb.jpg
                        )

                    [2] => stdClass Object
                        (
                            [title] => Real Crime Profile - Real Crime Profile
                            [id] => Podcast talking about criminal cases and personality profiling.
                            [artistName] => Real Crime Profile
                            [feedUrl] => http://feeds.soundcloud.com/users/soundcloud:users:202076064/sounds.rss
                            [primaryGenreName] => History
                            [artworkUrl60] => http://is5.mzstatic.com/image/thumb/Music69/v4/e4/0d/1e/e40d1efe-f625-8d15-4e2e-706fecead1e8/source/60x60bb.jpg
                        )

                )

        )

)

I've also tried array_merge_recursive($array1['entries'],$array2['entries'], but this give me something like this (6 objects [2 from one array and 4 from the other] instead of 3):

Array
(
    [0] => stdClass Object
        (
            [title] => Serial - This American Life
            [id] => Serial is a podcast from the creators of This American Life, hosted by Sarah Koenig. Serial unfolds one story - a true story - over the course of a whole season. 
        )

    [1] => stdClass Object
        (
            [title] => This American Life - This American Life
            [id] => This American Life is a weekly public radio show, heard by 2.2 million people on more than 500 stations. 
        )

    [2] => stdClass Object
        (
            [title] => Real Crime Profile - Real Crime Profile
            [id] => Podcast talking about criminal cases and personality profiling.
        )

    [3] => stdClass Object
        (
            [artistName] => This American Life
            [feedUrl] => http://feeds.serialpodcast.org/serialpodcast
            [primaryGenreName] => News & Politics

        )

    [4] => stdClass Object
        (
            [artistName] => This American Life
            [feedUrl] => http://feed.thisamericanlife.org/talpodcast
            [primaryGenreName] => Personal Journals
            [artworkUrl60] => http://is5.mzstatic.com/image/thumb/Music4/v4/1f/b8/0f/1fb80f69-bd94-8cad-0a2f-b082541d5f64/source/60x60bb.jpg
        )

    [5] => stdClass Object
        (
            [artistName] => Real Crime Profile
            [feedUrl] => http://feeds.soundcloud.com/users/soundcloud:users:202076064/sounds.rss

        )

)

Thoughts on how to merge these into 3 objects?

    This is only an example, to explain how you can use function multiArrayCombine from my answer to another question:

    foreach( $array['a']['entries'] as &$val ) $val = (array) $val;
    foreach( $array['b']['entries'] as &$val ) $val = (array) $val;
    
    $result = multiArrayCombine( $array['a']['entries'], $array['b']['entries'], T_OBJECT_CAST );
    
    $array['a']['entries'] = $result;
    unset( $array['b'] );
    
    print_r( $array );
    

    <kbd>eval.in demo</kbd>

    As I said, this is only an example: the function has the option to return objects but not to analyze it. You can modify it to process also objects and use it directly, without above first two lines.
