Php PDO会话的奇怪行为

php session

Php PDO会话的奇怪行为,php,session,pdo,Php,Session,Pdo,我的PDO会话有问题，需要一些调试帮助（顺便说一句，这似乎只发生在IE上）我有两个文件要测试 index.php和session2.php（如下所示） 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 );

我的PDO会话有问题，需要一些调试帮助（顺便说一句，这似乎只发生在IE上）

我有两个文件要测试 index.php和session2.php（如下所示）

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");
?>

在index.php的末尾，我有-->标题（“Location:session2.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");
?>

浏览器偶尔会处于以下状态：当我转到session2.php时，sessionid是不同的，当然会话数据也不见了

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");
?>

我有一个非常简单的PDOSession类，如下所示

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，它有一个不同的会话id。（打开/读取和关闭来自PDOSESSION类）

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");
?>

我不确定这些信息是否足以帮助任何人，但我真的被难住了

谢谢你的帮助
