How do I use filter_input to get parameter array?

Question

Well I have this page

domain.com/bla.php?p[]=1&p[]=2&p[]=3&p[]=4

Now, $_GET['p'] works as expected. It's an array

However, filter_input(INPUT_GET, 'p') produces false.

Now how do I get the array value of p using filter_input

As the documentation say, you should use the FILTER_REQUIRE_ARRAY flag:

filter_input(INPUT_GET, 'p', FILTER_DEFAULT, FILTER_REQUIRE_ARRAY)

Is it always going to be be an array? If so, filter_input_array could work for you: https://secure.php.net/manual/en/function.filter-input-array.php

Something like this should do the trick (untested):

$data = filter_input(INPUT_GET, 'p', FILTER_DEFAULT, FILTER_REQUIRE_ARRAY);

Maybe you could use:

print_r( filter_input_array ( INPUT_GET ));
