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

Try this

function flatCall($data_arr, $data_arr_call){
    $current = $data_arr;
    foreach($data_arr_call as $key){
        $current = $current[$key];
    }

    return $current;
}

OP's Explanation:

The $current variable gets iteratively built up, like so:

flatCall($data_arr, ['a','ab','abc']);

1st iteration: $current = $data_arr['a'];
2nd iteration: $current = $data_arr['a']['ab'];
3rd iteration: $current = $data_arr['a']['ab']['abc'];

You could also do if ( isset($current) ) ... in each iteration to provide an error-check.
