How to keep the order of nodes ?

[timmy78]

Hello.

I would like to know how to keep the order of nodes that have not the same tag.

For example :

$data = [
      'items' => [

      ]
  ];

$data['items']['poster'][] = 'Rank 1';

$data['items']['thumbnail'][] = 'Rank 2';

$data['items']['poster'][] = 'Rank 3';


$xml = (new ArrayToXml(
    array: $data,
    rootElement: [
        'rootElementName' => 'test',
        '_attributes'     => [
            'version' => '0.0',
        ],
    ],
    replaceSpacesByUnderScoresInKeyNames: true,
    xmlEncoding: 'UTF-8'
))->prettify()->toXml();

Produces :

<?xml version="1.0" encoding="UTF-8"?>
<test version="0.0">
  <items>
    <poster>Rank 1</poster>
    <poster>Rank 3</poster>
    <thumbnail>Rank 2</thumbnail>
  </items>
</test>

It should be one poster, then the thumbnail, and finally the last poster, like that :

<items>
    <poster>Rank 1</poster>
    <thumbnail>Rank 2</thumbnail>
    <poster>Rank 3</poster>
</items>

Is there a trick to do it ?

Thanks ! =)

I finally found a way to do it :

$data['items']['__custom:poster:1'][] = 'Rank 1';

$data['items']['__custom:thumbnail:3'][] = 'Rank 2';

$data['items']['__custom:poster:2'][] = 'Rank 3';
