我正在使用登錄系統，並且我試圖讓用戶登錄10天，除非他們明確註銷。我想通過使用session_set_cookie_params('864000');它會讓用戶保持登錄狀態10天。但至少在Chrome中這並不是這樣做的。用戶似乎只能在自動註銷之前以20-30分鐘的標準登錄。當我在Chrome瀏覽器中查看cookies時，我的URL中會列出兩個PHP會話Cookie，並在將來10天內有效日期。但是這似乎與登錄變量無關。大部分相關的代碼應該在下面。試圖獲得最近10天的登錄
任何想法爲什麼用戶未登錄10天？
由於提前，

在索引文件中，我有以下幾點：
require_once "header.php";
//content
include "login.php";
在header.php文件，下面是包括：
session_set_cookie_params('864000');
session_start();
在login.php文件中包含以下內容：
if (checkLogin($_POST['username'], $_POST['password']))
{
show_userbox();
}
下面是函數「checkLogin」：
function checkLogin($u, $p)
{
global $seed; // global because $seed is declared in the header.php file
if (!valid_username($u) || !valid_password($p) || !user_exists($u))
{
return false; // the name was not valid, or the password, or the username did not exist
}
//Now let us look for the user in the database.
$query = sprintf("
SELECT loginid
FROM login
WHERE
username = '%s' AND password = '%s'
AND disabled = 0 AND activated = 1
LIMIT 1;", mysql_real_escape_string($u), mysql_real_escape_string(sha1($p . $seed)));
$result = mysql_query($query);
// If the database returns a 0 as result we know the login information is incorrect.
// If the database returns a 1 as result we know the login was correct and we proceed.
// If the database returns a result > 1 there are multple users
// with the same username and password, so the login will fail.
if (mysql_num_rows($result) != 1)
{
return false;
} else
{
// Login was successfull
$row = mysql_fetch_array($result);
// Save the user ID for use later
$_SESSION['loginid'] = $row['loginid'];
// Save the username for use later
$_SESSION['username'] = $u;
// Now we show the userbox
return true;
}
return false;
}
