Write a function in PHP, named printList, that takes 2 parameters (only!): a string, and a nested array.
The function will generate a string with the value of each element on a separate line.
The value will be preceded by the string and also indicate the position and index within the array.

ie.

$list = array("stringA", array("a", "b", "c"), "stringB", array("stringC"));
with a call like printList("Foo", $list) would result in:

Foo[0] = stringA
Foo[1][0] = a
Foo[1][1] = b
Foo[1][2] = c
Foo[2] = stringB
Foo[3][0] = stringC

{
    foreach ($input as $key => $value) {
        $output = "{$outputBase}[{$key}]";
        if (is_array($value) && count($value)) {
            // handle array recursively
            print printList("{$output}", $value);
        } else if (is_array($value) && count($value) == 0) {
            // handle empty array value
            print "{$output} = " . PHP_EOL;
        } else {
            // handle non-array value
            print "{$output} = $value" . PHP_EOL;
        }
    }
}

printList("Foo00", array( null, [], "stringA", array("a", "b", "c", array(1, 2, 3)), "stringB", array("stringC")));
