Php 如何通过fsockopen将会话传递到新套接字？

我需要通过php中的fsockopen将会话传递给异步调用

您能帮我将会话传递到新套接字吗

解决方案：

下面的代码可以工作

start.php

<?php
session_start();
$_SESSION['var1'] = 'value1';
async_call('/async.php');
echo '<pre>';
print_r($_SESSION);
echo $_COOKIE['PHPSESSID'] . "\r\n";
echo '<a href="verify.php">verify.php</a>';

function async_call($filepath) {
    $host = 'sandbox'; // set to your domain
    $sock = fsockopen($host, 80);
    fwrite($sock, "GET $filepath HTTP/1.1\r\n");
    fwrite($sock, "Host: $host\r\n");
    fwrite($sock, "Cookie: PHPSESSID=" . $_COOKIE['PHPSESSID'] . "\r\n");
    fwrite($sock, "Connection: close\r\n");
    fwrite($sock, "\r\n");
    fflush($sock);
    fclose($sock);
}
?>

<?php
$logfile = 'debug.log';
echo '<a href="start.php">start.php</a>';
echo '<pre>' . file_get_contents($logfile);
?>

<?php
session_start();

我可以让它在本地工作，但事实证明，我所登台的共享主机没有任何文档，不允许使用fsockopen。在我自己的服务器上一切都很好。谢谢你的帮助。

谢谢你的帮助，安德烈亚斯。事实证明，我登台的共享主机在没有任何文档的情况下被禁止使用fsockopen。这就是为什么我可以让它在本地工作，但不能在临时服务器上工作

我知道phpsessid被保存为cookie，但我不清楚如何检索它以访问异步脚本中的会话变量。检查您前面的问题，我添加了一个回答，应该可以解决这个问题。为了清晰起见，我编辑了这篇文章。安德烈亚斯，你帮了我不少忙，但不知什么原因，我还是被困住了。你能看看我上面的简单调试脚本，看看我遗漏了什么吗？那是因为你犯了一个错误，或者我的指令不是100%清楚。它应该是

fwrite（$sock，“Cookie:PHPSESSID=“.$\u Cookie['PHPSESSID']）”\r\n）啊哈。。。知道了。。。php必须有一个会话\u start（）。我将确认我的主脚本工作，然后更新它以反映成功。
