Question

我有以下情况：

PHP持久套接字服务器使其在无限循环中通过控制台运行

这是我的server.php并使用＆＃39;运行一次。 php server.php＆＃39;命令行命令。

    <?php
    // set some variables
    $host = "127.0.0.1";
    $port = 3000;
    // don't timeout!
    set_time_limit(0);
    // create socket
    $socket = socket_create(AF_INET, SOCK_STREAM, 0) or die("Could not create socket\n");
    // bind socket to port
    $result = socket_bind($socket, $host, $port) or die("Could not bind to socket\n");
    while(true) {
        // start listening for connections
        $result = socket_listen($socket, 3) or die("Could not set up socket listener\n");
        // accept incoming connections
        // spawn another socket to handle communication
        $spawn = socket_accept($socket) or die("Could not accept incoming connection\n");
        // read client input
        $input = socket_read($spawn, 1024) or die("Could not read input\n");
        // clean up input string
        $input = trim($input);
        echo "Client Message : ".$input;
        // reverse client input and send back
        $output = strrev($input) . "\n";
        echo socket_send($spawn, $output, strlen ($output), 0) or     die("Could not write output\n");
        // close sockets
     }
     socket_close($spawn);
     socket_close($socket);
    ?>

此文件中的Client.php我向socket服务器发送消息：此时我成功将消息发送到我的套接字服务器。

<?php
$host    = "127.0.0.1";
$port    = 3000;
$message = "Abhi ye sab kaise karen ahm asdasdasdasd";
//echo "Message To server :".$message;
// create socket
$socket = socket_create(AF_INET, SOCK_STREAM, 0) or die("Could not create socket\n");
// connect to server
$result = socket_connect($socket, $host, $port) or die("Could not connect to server\n");  
// get server response
//Send the message to the server
if( ! socket_send ( $socket , $message , strlen($message) , 0))
{
       $errorcode = socket_last_error();
       $errormsg = socket_strerror($errorcode);
       die("Could not send data: [$errorcode] $errormsg \n");
} else {
       echo "Message send successfully \n".$message;
}
//socket_close($socket);
?>

Receiver.php另一个文件，我想接收我的套接字服务器正在发送的响应，这是无法正常工作的，并且它一直在加载而没有给出任何输出。

<?php
$host    = "127.0.0.1";
$port    = 3000;
$message = "Abhi ye sab kaise karen ahm ";
//echo "Message To server :".$message;
// create socket
$socket = socket_create(AF_INET, SOCK_STREAM, 0) or die("Could not create socket\n");
// connect to server
$result = socket_connect($socket, $host, $port) or die("Could not connect to server\n");  
// get server response
//Send the message to the server
while(true){
    $from = '';
    $port = 3000;
    echo socket_recvfrom($socket, $buf, 12, 0, $from, $port);

    echo "Received $buf from remote address $from and remote port $port" . PHP_EOL;
}
//socket_close($socket);
?>

我的接收方端没有收到任何输出。我想这样做：

从客户端发送消息到套接字服务器，一旦套接字服务器发送它我的接收端显示它，我只成功到客户端，我client.php发送消息到server.php但是receiver.php没有收到任何的事情。

由于

php中的socket通过持久连接发送接收消息
