我的 PDOSessions 有问题并寻求一些帮助调试（顺便说一句，这似乎只发生在 IE 上）

我有两个用于测试 index.php 和 session2.php 的文件（如下）

在 index.php 最后我有 ---> header("Location: session2.php");

偶尔浏览器会进入一个状态，当我去 session2.php 时 sessionid 是不同的，当然会话数据已经消失了

我有一个非常简单的 PDOSession 类，见下文

这是日志文件中的调试语句。出于某种原因，当我转到 session2.php 时，它具有不同的会话 ID。（OPEN/READ 和 CLOSE 来自 PDOSESSION 类）

我不确定这是否足以让任何人提供帮助，但我真的很难过..

谢谢你的帮助

[PDOSession] index.php OPEN 
[PDOSession] index.php READ id=vpodh6fornta10mg2lqkns2qb1
[11.20.12 8:33:09][session1]
[11.20.12 8:33:09][session1]->just before forwarding to session2.php
[11.20.12 8:33:09][session1][vpodh6fornta10mg2lqkns2qb1] Array
(
[TstpageID] => 1
)

[PDOSession] index.php WRITE id=vpodh6fornta10mg2lqkns2qb1
[PDOSession] index.php CLOSE 
[PDOSession] session2.php OPEN 
[PDOSession] session2.php READ id=f7s4u3bc1hbo0s0dj3s9o8g1u7
[11.20.12 8:33:09][session2]
[11.20.12 8:33:09][session2][f7s4u3bc1hbo0s0dj3s9o8g1u7] Array
(
)

[PDOSession] session2.php WRITE id=f7s4u3bc1hbo0s0dj3s9o8g1u7
[PDOSession] session2.php CLOSE

这是 index.php 

require 'functions.php';
$link = new PDO("mysql:host=".DB_HOST.";dbname=".DB_NAME, DB_USER, DB_PASSWD);
$link->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );

PDOSession::init($link);    
errorLog("[session1]\n");

$pageID = 1 ;

$_SESSION['TstpageID'] = $pageID;
errorLog("[session1]->just before forwarding to session2.php\n");
errorLog("[session1][".session_id()."] ".print_r($_SESSION,true)."\n");
header("Location: session2.php");
?>

这是 session2.php

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<?php
set_include_path('/home/unitnetfb/html/inc');

$noFACEBOOK_INIT = 1;
require 'functions.php';
$link = new PDO("mysql:host=".DB_HOST.";dbname=".DB_NAME, DB_USER, DB_PASSWD);
$link->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );

PDOSession::init($link);    

errorLog("[session2]\n");

errorLog("[session2][".session_id()."] ".print_r($_SESSION,true)."\n");
?>

这是 PDO 会话类

问题是带有 IE 的 iframe 中的第三方 cookie

header('P3P:CP="IDC DSP COR ADM DEVi TAIi PSA PSD IVAi IVDi CONi HIS OUR IND CNT"');
