I am not a programmer than... If I see that it must be an array, I pass array, not null.

Yes? I just tried:

<?php

function foo(array $al) {
        echo 'La-la' . chr(10);
}

foo(null);

?>

Catchable fatal error: Argument 1 passed to foo() must be an array, null given, called in /Users/dima/1.php on line 7 and defined in /Users/dima/1.php on line 3

So null is not valid when array is expected.
