如何使用动态更改的键值访问嵌套的JSON对象

Question

I'm trying to get JSON data into my PHP script and the problem is that this is a nested JSON object with dynamically changed key value (I've converted JSON objects into PHP objects):

stdClass Object
(
    [665261] => stdClass Object
        (
            [id] => 665261
            [SpeiseplanName] => Campus Mensa Wismar
            [Datum] => 2019-07-12
            [KstNr] => 462
            [ArtikelText] => ein Brathering ohne Mittelgräte
            [ZusatzStoffe] => 9 Fi Gl
            [ZusatzStoffeText] => mit Süßungsmittel, Fische, Gluten
            [PeStud] => 0.75
            [PeBed] => 1.35
            [PeGast] => 1.75
            [sortierung] => 46
        )

    [665262] => stdClass Object
        (
            [id] => 665262
            [SpeiseplanName] => Campus Mensa Wismar
            [Datum] => 2019-07-12
            [KstNr] => 462
            [ArtikelText] => zwei Bratheringe ohne Mittelgräte
            [ZusatzStoffe] => 9 Fi Gl
            [ZusatzStoffeText] => mit Süßungsmittel, Fische, Gluten
            [PeStud] => 1.25
            [PeBed] => 1.9
            [PeGast] => 2.25
            [sortierung] => 47
        )

    [665263] and so on.

So, I've already get the data like this:

<p id="desc"><?= htmlReady(_($data[665261]['ArtikelText'])) ?></p>

The output was then "zwei Bratheringe ohne Mittelgräte" as expected. But this numeric key 665261 is dynamic and changed every day.

So how can I access date with key's values like this? Thank you for your help.

You just need to use foreach loop, like this:

Suppose your object of objects name is $objects:

foreach ($objects as $obj) {
    echo '<p id="desc">' . htmlReady(_($obj->ArtikelText)) . '</p>';
}

Or if you have a array of arrays, with the name of $arrays:

foreach ($arrays as $arr) {
    echo '<p id="desc">' . htmlReady(_($arr['ArtikelText'])) . '</p>';
}
