HomeBackend DevelopmentPHP Tutorial PHP+SOCKET 由于套接字没有连接并且没有提供地址,发送或接收数据的请求没有被接受

求助:PHP+SOCKET 由于套接字没有连接并且没有提供地址,发送或接收数据的请求没有被接受。

本帖最后由 subendong 于 2011-06-03 16:39:41 编辑 由于之前连续发布了两篇帖子,无一有回,所以先向版主申请删除之前两篇类似的帖子,不然留着无用。就像垃圾一样。
然后希望大神,能根据我提供的代码,稍作修改,使得代码能够正确运行,谢谢!

具体如下:
Warning: socket_read(): unable to read from socket [0]: 由于套接字没有连接并且(当使用一个 sendto 调用发送数据报套接字时)没有提供地址,发送或接收数据的请求没有被接受。
我建了两个文件xx.php是在服务器端执行的文件。x.php是在客户端执行的文件。
xx.php
<?php <br />
// 设置一些基本的变量 <br />
global $lat,$lnt;<br />
$host = "192.168.1.110"; <br />
$port = 8080; <br />
// 设置超时时间 <br />
set_time_limit(0); <br />
// 创建一个Socket <br />
$commonProtocol = getprotobyname("tcp");<br />
$socket = socket_create(AF_INET, SOCK_STREAM, $commonProtocol);<br />
<br />
//绑定Socket到端口 <br />
$result = socket_bind($socket, $host, $port) or die("Could not bind to socket\n"); <br />
$ret = socket_listen($socket, 5);<br />
if($ret)<br />
{<br />
    while (true)<br />
    {<br />
        $spawn = socket_accept($socket);<br />
        if(!$spawn) break;<br />
        $output = "congratulations,you have connected server:" . $host . "!";<br />
        socket_write($spawn, $output, strlen ($output)) or die("error\n"); <br />
        $input = socket_read($socket, 100000);<br />
        socket_write($spawn, $input, strlen ($input)) or die("error\n"); <br />
        socket_close($spawn);<br />
    }<br />
}<br />
socket_close();<br />
?><br />




x.php
<?php <br />
// 设置一些基本的变量 <br />
$host = "192.168.1.110"; <br />
$port = 8080; <br />
// 设置超时时间 <br />
set_time_limit(0); <br />
// 创建一个Socket <br />
$commonProtocol = getprotobyname("tcp");<br />
$socket = socket_create(AF_INET, SOCK_STREAM, $commonProtocol);<br />
if(!$socket) echo "can't creat socket";<br />
//绑定Socket到端口 <br />
<br />
$result = socket_connect($socket,$host,$port);<br />
if($result)<br />
{<br />
    $output="abc";<br />
    socket_write($socket, $output, strlen ($output));<br />
    $input = socket_read($socket, 1024);<br />
}<br />
echo $input;<br />
?>



在服务器先打开xx.php,然后再在客户端打开x.php,结果服务器端提示以上错误信息,就是socket_read的错误。
哪位大神帮我看下,找了好多资料都没解决。

------解决方案--------------------
我给你个可用的测试例
// Client <br>
// 设置错误处理<br>
error_reporting (E_ALL);<br>
// 设置处理时间<br>
set_time_limit (0);<br>
<br>
$ip = "";       // IP 地址<br>
$port = 1000;            // 端口号<br>
<br>
$socket = socket_create (AF_INET, SOCK_STREAM, SOL_TCP);   // 创建一个SOCKET<br>
if ($socket)<br>
    echo "socket_create() 成功!<br>\n";<br>
else<br>
    echo "socket_create() 失败:".socket_strerror ($socket)."<br>\n";<br>
<br>
$conn = socket_connect ($socket, $ip, $port);       // 建立SOCKET的连接 <div class="clear">
                 
              
              
        
            </div>

The best way to send emails is to use the PHPMailer library. 1) Using the mail() function is simple but unreliable, which may cause emails to enter spam or cannot be delivered. 2) PHPMailer provides better control and reliability, and supports HTML mail, attachments and SMTP authentication. 3) Make sure SMTP settings are configured correctly and encryption (such as STARTTLS or SSL/TLS) is used to enhance security. 4) For large amounts of emails, consider using a mail queue system to optimize performance.

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.
