?>

and

$page's result is 1. but i try www.example.com/test.php?page=3

$page's result is still output 1.

At first you should check if is page setted, then you can access page

try this:

if(isset($_GET['page'])){
    $page = $_GET['page'] ? intval($_GET['page']) : 1;
    echo "current page : ".$page."<br/>";
}

here is the result i am getting:
