how to create a custom name object

[HDeriauFF]

Hi there

I need to dynamically recreate an array in order to correctly alter a session

here is my issue

What I need:

Code:

[SerialItems] => Array
                        (
                            [ABLE_11/18/20] => SerialItem Object
                                (
                                    [BundleRef] => ABLE_11/18/20
                                    [BundleQty] => 16
                                    [ExpiryDate] => 11/18/2020
                                )

                        )

when recreate my array $LnItm->SerialItems[], I get a stdClass Object instead:

Code:

[SerialItems] => Array
                        (
                            [ABLE_11/18/20] => stdClass Object
                                (
                                    [BundleRef] => ABLE_11/18/20
                                    [BundleQty] => 16
                                    [ExpiryDate] => 11/18/2020
                                )

                        )

What do I need to do to change the stdClass Object to SerialItem ?

Thanks!
