Dynamically accessing multidimensional array value

Question

I\'m trying to find (or create) a function. I have a multidimensional array:

$data_arr = [
    \"a\" => [
        \"aa\" => \"abfoo\",
        \"ab\"          


        

Answer 1

You need a function like this:

function getValue($data_arr, $data_arr_call) {
    foreach ($data_arr_call as $index) {
        if (isset($data_arr[$index])) {
            $data_arr = $data_arr[$index];
        } else {
            return false;
        }
    }
    return $data_arr;
}

And use it like this:

$data_arr = [
    "a" => [
        "ab" => [
            "abc" => "abbfoo",
        ],
    ],
];
$data_arr_call = ["a", "ab", "abc"];
$value = getValue($data_arr, $data_arr_call);
if ($value) {
    // do your stuff
}
