我付钱请程序员制作购物篮脚本以使用 Spreadshirt API。一切都运行良好，除了篮子自己不断清空。我认为 session 在某个时候丢失了，因此脚本创建了另一个 BasketId。
我试图找出它发生的具体原因，但没有成功...我无法重现该错误。它只是随机发生，没有任何原因。关闭浏览器、重置 apache 甚至整个网络服务器都不会导致 session 丢失。
我有两个不同的脚本在同一个域上使用 cookie，它们没有任何问题(一个是用于管理员登录 session 的 cookie，另一个 cookie 用于保存用户在商店中最后查看的文章)
我尝试了在谷歌上找到的所有解决方案但没有成功:编辑 php.ini ，通过 php 强制 ini 设置，尝试了 htaccess 方式，...
这是我的 phpinfo 的“ session ”部分:http://gyazo.com/168e2144ddd9ee368a05754dfd463021

还有脚本的其他两个部分:一个用于将 sample T 恤添加到购物篮的表单 (example.php) 和一个调用 ajax 的脚本 (shop-controller.js )。如果需要可以发布，但没有 session 处理内容。
更新 - 也许问题与 session 无关。 BasketId 丢失，但 PHPSESSID 在浏览器 cookie 中保持不变。
我在过去 3 天做了以下测试(使用不同的计算机和浏览器进行了测试):
清空浏览器 cookie，然后在下午开始新的 session
将 1 件商品添加到购物篮，我记下 BasketId 并检查浏览器 cookie 以记下 PHPSESSID
通常总是在午夜左右，篮子自己空了
PHPSESSID 在我的浏览器 cookie 中保持不变，即使在购物篮自行清空之后也是如此
但是BASKETID不一样，下午用的丢了重新生成一个

最佳答案
首先您需要确定问题是出在 session 的垃圾回收中还是代码中的逻辑错误。为此，您可以:
// Add this right after session_start()
if (!isset($_SESSION['mySessionCheck'])) {
$_SESSION['mySessionCheck'] = "This session (" . session_id() . ") started " . date("Y-m-d H:i:s");
}
// For HTML pages, add this:
echo '<!-- ' . $_SESSION['mySessionCheck'] . ' -->';
// For AJAX pages, add "mySessionCheck" to the JSON response:
echo json_encode(
array(
"c" => array(
"u" => $_SESSION['checkoutUrl'],
"q" => $basketData[0],
"l" => $basketData[1]
),
"mySessionCheck" => $_SESSION['mySessionCheck']
)
);
如果此消息在篮子清空的同时发生变化，那么您肯定会知道这是 PHP session 的问题。
在这种情况下，您可以尝试以下几种方法:
1)你在做什么
$lifetime=60 * 60 * 24 * 365;
$domain = ".mywebsite.com";
session_set_cookie_params($lifetime,"/",$domain);
@session_start();
但是根据user contributed note来自 PHP.net 文档:
PHP's Session Control does not handle session lifetimes correctly when using
session_set_cookie_params().
因此您可以尝试使用 setcookie() 代替:
$lifetime=60 * 60 * 24 * 365;
session_start();
setcookie(session_name(),session_id(),time()+$lifetime);
尽管评论中指出这是一个 4 年前的记录，但我对其进行了测试并且它仍然发生(我在 PHP 5.5.7、Windows Server 2008、IIS/7.5 上)。只有 setcookie() 生成 HTTP header 以更改到期日期(例如将 $lifetime 设置为 600):
Set-Cookie: PHPSESSID=(the id); expires=Mon, 22-Jun-2015 15:03:17 GMT; Max-Age=600
2) 如果您使用的是 Debian 服务器或某些衍生产品，它们 use a cron job to clear out PHP sessions ，所以你可以尝试:
3) 要查看是否有进程清除您的 session ，您可以查看 session 文件存储的目录(实际路径因服务器而异，使用session_save_path 查找位置你的)。我不是服务器管理员，但我读过你可以使用 auditctl为此，请确保您登录 who made the changes to your files .
4) 如果您无权访问服务器配置，或者不想依赖服务器配置(如果您切换主机则很好)，您可以实现自己的 session 处理程序。看看这个 example by Pedro Gimeno .
