PHP套接字:无法连接[10048]:通常只允许使用每个套接字地址(协议/网络地址/端口)

我运行server.php,然后在几次尝试从客户端发送到服务器后,在client.php屏幕上运行client.php并显示此警告。

警告:socket_connect():无法连接[10048]:通常只允许使用每个套接字地址(协议/网络地址/端口)。在第32行的C:\ xampp \ htdocs \ client.php中,套接字连接失败!

之后xampp停止工作。

这是server.php

<!DOCTYPE html>
<html>
<?php
  error_reporting(0);
  set_time_limit(0);
  ob_implicit_flush();
  $host = "127.0.0.1";
  $port = 65535;
  echo "Waiting for connections... \n";
  $socket = socket_create(AF_INET, SOCK_STREAM, 0) or die("Could not create socket\n");

  $result = socket_bind($socket, $host, $port) or die("Could not bind to socket\n");

  $result = socket_listen($socket) or die("Could not set up socket listener\n");

  while(1){
    $spawn[++$i] = socket_accept($socket) or die("Could not accept incoming connection\n");
    echo "\n";
    $input = socket_read($spawn[$i],1024);
    $client = $input;

    echo $client ."\n";

    socket_close($spawn[$i]);
    echo "\n";

   }
 socket_close($socket);
?>
</html>

这是我的client.php

<!DOCTYPE html>
<html>
<body>
<form method="post" action="client.php">
<p><h4><label>Type Your Message Here:<input name = "message" size = "25" maxlength = "30" required></label></h4></p>
<input type="submit" name="sendmsg" class="btn btn-primary" value="send message"/>
</form>
<?php
$user="abc";
if(empty($_POST)){

}
elseif(isset($_POST['sendmsg'])) {
    $message =$_POST["message"];

while(1){

if($message=='q') { exit; }
$socket= socket_create(AF_INET,SOCK_STREAM,SOL_TCP);
    if($socket===false)
    {
        echo "Socket creation failed!";
    }
$result = socket_connect($socket,"127.0.0.1",65535);
if($result===false)
{
    echo "Socket connection failed!";
}
    else {
        if($message !='0'){
        socket_write($socket,"$user says --> $message",1024);
        $message='0';
        }

     }
     socket_close($socket);
}

}
?>

</body>

</html>

答案 0 :(得分:1)

您在POST内不断创建,连接和关闭套接字,它们之间的延迟最小。您可能正在使用所有可用端口作为原始端点,因为关闭套接字需要一些时间。

您是否只想在页面{{1}}添加新邮件时才创建连接?
