Php 使用端口连接时，从URL获取所有标头

我正忙于使用跟踪脚本来处理连接并从跟踪单元读取信息。但制造商向我解释的方式是，该装置发送的信息类似于URL，并连接到TCP端口，例如：7203

现在我的问题是：在使用端口时，如何获取连接到服务器的单元的头文件？我还从Linux命令行运行代码

下面是我用来打开端口的代码：

#!/usr/bin/php -q
<?php
    error_reporting(E_ALL);
    ini_set('display_errors', 1);
    set_time_limit(0);
    ob_implicit_flush();
    $ip = 'IP of my server';
    $port = '7203';
    $__server_listening = true;

    declare(ticks = 1);

    become_daemon();

    /* nobody/nogroup, change to your host's uid/gid of the non-priv user 

    ** Comment by Andrew - I could not get this to work, i commented it out
       the code still works fine but mine does not run as a priv user anyway....
       uncommented for completeness

#/usr/bin/php-q
可以将与此命令一起使用

php-S localhost:7203

或者，如果使用apache http服务器，请在配置文件中使用

听*：7203

是HTTP协议吗？然后将http服务器配置为在该端口上侦听。如果不是，你应该问什么是协议。嗨，是的，对不起，我读到这是一个HTTP协议。我不太熟悉如何设置HTTP服务器来侦听端口。你可能有我可以使用的示例代码吗？在第198行-你发布的代码不到198行，所以我怀疑是它产生了错误。我尝试过php-S localhost:7203，但在Putty中收到以下错误：[Wed Dec 4 09:49:39 2013]41.13.4.237:59024无效请求（格式错误的HTTP请求）。可能是什么问题？http请求调用要执行的php脚本。您需要给我http头，以查看服务器接收到什么以及如何应答。我认为您应该考虑使用NoDE.js，因为它似乎是一个特殊的URL请求。
