Is_array detect array, result returns false

Source: Internet
Author: User
echo $res;var_dump($res);var_dump(is_array(res));

$res is the result of the database query, the result returns an array, and no result returns false. But now even if $res is an array, it is also flase. The following is the display result.

Arrayarray(3) { ["ID"]=> string(1) "1" ["USERNAME"]=> string(4) "root" ["NICKNAME"]=> string(17) "复仇者联盟~~" } bool(false)

Is the reason for PHP configuration?
