Sort associative arrays nested within other nested associative arrays (3 levels) in php

I'm aiming to alphabetically order by name the last nesting level.

I've tried all different kinds of sort functions sort(), asort(), ksort()... , but I didn't end up with the needed results.

The array

$lang_txt_array1 = [
    'Dutch' => [
        ['name' => 'Kiburg, Natalie', 'ext' => 'None 5977'],
    ],
    'French' => [
        ['name' => 'Clausen, Katie', 'ext' => '(608) 5205'],
        ['name' => 'Viglucci, Maria Tina', 'ext' => '(429) 6713'],
    ],
    'German' => [
        ['name' => 'Pries, Nelli', 'ext' => '(289) 5846'],
        ['name' => 'Calhamer, Tatiana', 'ext' => '(289) 5838'],
    ],
    'Indonesian' => [
        ['name' => 'Meyer, Alexandra', 'ext' => '(931) 2094'],
    ],
    'Korean' => [
        ['name' => 'Yoon, Matthew', 'ext' => 'None 5990'],
    ],
    'Laotian' => [
        ['name' => 'Inthavong, Andrew', 'ext' => 'None 4695'],
    ],
    'Lithuanian' => [
        ['name' => 'Paulius, Vilija', 'ext' => '(289) 5817'],
    ],
    'Polish' => [
        ['name' => 'Arciuch, Eva', 'ext' => '(608) 5024'],
    ],

My attempts

ksort($lang_txt_array1);

array_multisort($lang_txt_array1[0][1][2]);

uasort($lang_txt_array1, function ($a, $b) {
    return strcmp($a[0], $b['name']);
});

function sortByAge($a, $b)
{
    return $a['name'] > $b['name'];
}

usort($lang_txt_array1, 'sortByAge'); //$people is now sorted by age (ascending)

sort($lang_txt_array1, ksort($lang_txt_array1));

function cmp_sort($x, $y)
{           //your function to compare two keys
    if ($x === $y)
        return 0;
    else
        return ($x < $y ? 1 : -1);
}

uasort($lang_txt_array1, 'cmp_sort');    //call user-defined compare function*/

function method1($a, $b)
{
    return ($a[2]["name"]["dept"] <= $b[2]["name"]["dept"]) ? -1 : 1;
}
usort($array, "method1");

// Sorting the people within the languages
foreach($lang_txt_array1 as $lang => $arr){
    usort($arr, fn($a, $b) => strcmp($a['name'], $b['name']));
    $lang_txt_array1[$lang] = $arr;
}

// Sorting languages according to their first person
uasort($lang_txt_array1, fn($a, $b) => strcmp($a[0]['name'], $b[0]['name']));

print_r($lang_txt_array1);

Demo

$result = array_map(function ($items) {
  $names = array_column($items, 'name');
  array_multisort($names, $items);
  return $items;
}, $array);

I was able to get it working, finally, by use what was suggested earlier, but, I must have had a type, because it now works.

I read my dynamically created array and used a foreach to read each line. Then I did a usort to compare each line in each language array:

foreach ($lang_txt_array1 as $keys => $langs) {
    usort($langs, 'cmp');
    $lang_txt_array1[$keys] = $langs;
}

function cmp($a, $b)
{
    return strcmp($a["name"], $b["name"]);
}

Thanks for all the help, and if I ask again, I will try to be better at getting my question across.
