我在（至少）Google Chrome 和 Safari 中遇到了问题。
首次尝试登录时，不会重定向用户。会话已创建，但几乎就像未检测到一样，并将用户带回索引页面。在第二次尝试时，会发出正确的重定向并将用户带到正确的页面。
该脚本在 Firefox 中运行良好，我已经广泛检查以查看是否返回了正确的数据，确实如此。我已经搜索了，我已经搜索了，我已经搜索了，但不幸的是没有发现任何有用的东西。
Access.php - 用户登录
<?php
session_start();
ob_start();
include_once('db.class.php');
include_once('register.class.php');
include_once('login.class.php');
$db = null;
$reg = null;
$log = null;
$db = new Database();
$log = new Login($db, null, null, null, null, null, null);
if (isset($_SESSION['login'])) {
$log->redirectUser($_SESSION['login']);
}
include_once('includes/header.html');
?>
Some HTML...
<?php
if (isset($_POST['logsub'])) {
$db = new Database();
$log = new Login($db, $_POST['email'], $_POST['pass']);
$validation = &$log->validate();
if(empty($validation)) {
$log->redirectUser($_SESSION['login']);
} else {
echo "<div id='error'><div class='box-error'><p style='font-weight: bold'>The following errors occured...</p><ul>";
for ($i = 0; $i < count($validation); $i++) {
echo "<li>" . $log->getErrorMessage($validation[$i]) . "</li>";
}
echo "</ul></div></div>";
}
}
?>

重申一下，问题仅存在于 Google Chrome 和 Safari（我的 iPhone 上的 Safari）中，并且纯粹存在于登录方面。在第一次尝试时，会话将被忽略（它被创建），而在第二次尝试时，用户将被重定向。
有任何想法吗？我尝试了多种可能...

我现在知道问题出在哪里了。
当调用重定向时，它会将用户发送到 details.php 页面。但是，此页面包含以下代码片段：
if (!isset($_SESSION['login'])) {
header("Location: fbedder/index.php");
}
显然，正在发生的事情是会话没有被检测/保存/“随便”，因此将用户发送回索引页面。有没有办法确保 $_SESSION 不会有效丢失。我在这里发帖之前已经阅读过这个，这就是我插入的原因session_write_close()，但这似乎并没有达到预期的效果。
