如何在没有键的数组上正确使用filter_input_array？

Question

I have in my $_POST array a variable without keys: (This is from an input form with name[]).

var_dump($_POST) looks like this:

array(2) {
  ["name1"]=>
  string(1) "ttt"
  ["name2"]=>
  array(1) {
    [0]=>
    string(2) "test"
  }
}

How can I correctly use filter_input_array on this array?

For example, I need use FILTER_VALIDATE_INT to all name2 elements.

UPD: print_r of $_POST:

Array
(
    [name1] => ttt
    [name2] => Array
        (
            [0] => test
        )
)

Answer 1

$args = array(
'name1'   => SOME_FILTER // this is for example,

'name2'   => array(
                        'filter' => FILTER_VALIDATE_INT,
                        'flags'  => FILTER_REQUIRE_SCALAR,
                       ),

);

$myinputs = filter_input_array(INPUT_POST, $args);

var_dump($myinputs); echo " ";
