json decode with foreach

[hyster]

I have a json data set that I'm trying to loop and echo but part of the dataset changes for each set of data.

I'm stuck on the $data,[????][name_il8n] .

how do I loop the part with the ???? when I just need the [name_il8n] data ??

 

sample of the dataset

    "status": "ok",
    "meta": {
        "count": 43
    },
    "data": {
        "92_stalingrad": {
            "name_i18n": "Stalingrad"
        },
        "36_fishing_bay": {
            "name_i18n": "Fisherman's Bay"
        },
        "05_prohorovka": {
            "name_i18n": "Prokhorovka"
        },
        "101_dday": {
            "name_i18n": "Overlord"
        },
}

code so far

$jsonurl = "https://api.worldoftanks.eu/wot/encyclopedia/arenas/?application_id$app_id";
$json = file_get_contents($jsonurl,0,null,null);
$output = json_decode($json, true);

foreach ($output['data']['????']['name_i18n'] as $item){
echo "<option>".$item['name_i18n']."</option>";
}

thanks for any help
