我有一个登录脚本，它在托管在共享主机（Windows8 服务器）上的生产服务器上运行良好。
在 WindowsXP 和 UniServ（如 XAMPP 或 WAMP）的本地服务器（未连接到 Internet）上尝试相同的脚本。它只是给出一个空白屏幕。
因此，如果 Apache / Mysql / PHP 中有任何问题，我尝试测试一些脚本。所有 3 都在 Uniserv 上运行良好。
我尝试检查会话路径的配置，一切都很好。如果相同的文件必须在本地服务器上工作，不确定还需要检查什么。需要帮忙。
请检查以下登录脚本：
<?php // accesscontrol.php
include_once 'common.php';
include_once 'db2.php';
session_start();
$uid = isset($_POST['uid']) ? $_POST['uid'] : $_SESSION['uid'];
$pwd = isset($_POST['pwd']) ? $_POST['pwd'] : $_SESSION['pwd'];
if(!isset($uid)) {
?>
