Question

使用以下代码，我可以收到1个请求并写下来：

function listen()
{
    // Set time limit to indefinite execution
    set_time_limit (0);

    // Set the ip and port we will listen on
    $address = 'XX.XX.XX.XXX';
    $port = XXXX;

    // Create a TCP Stream socket
    $sock = socket_create(AF_INET, SOCK_STREAM, 0);

    // Bind the socket to an address/port
    $bind = socket_bind($sock, $address, $port);

    // Start listening for connections
    socket_listen($sock);

    /* Accept incoming requests and handle them as child processes */
    $client = socket_accept($sock);

    // Read the input from the client &#8211; 1024 bytes
    $input = socket_read($client, 2024);

    // Strip all white spaces from input
    echo $input;

    // Close the master sockets
    $close = socket_close($sock);

    var_dump($close);
}

listen();

但是一旦收到1个数据包就会自动收听。我需要继续接收数据包，直到收到退出或任何关闭命令。

我应该如何更改上面的代码才能使这个函数成为循环？

Answer 1

set_time_limit (0);

$address = '46.49.41.188';

$port = 7777;
$con = 1;
$word = "";

$sock = socket_create(AF_INET, SOCK_STREAM, 0);
$bind = socket_bind($sock, $address, $port);

socket_listen($sock);

while ($con == 1)
{
    $client = socket_accept($sock);
    $input = socket_read($client, 2024);

    if ($input == 'exit') 
    {
        $close = socket_close($sock);
        $con = 0;
    }

    if($con == 1)
    {
        $word .= $input;
    }
}

echo $word;

如果请求将退出侦听将关闭。该方法已经过测试:)并且可以正常工作。

怎么样：

function listen(){
// Set the ip and port we will listen on
$address = 'XX.XX.XX.XXX';
$port = XXXX;
// Create a TCP Stream socket
$sock = socket_create(AF_INET, SOCK_STREAM, 0);
// Bind the socket to an address/port
$bind = socket_bind($sock, $address, $port);
// Start listening for connections
socket_listen($sock);
/* Accept incoming requests and handle them as child processes */
$client = socket_accept($sock);
// Read the input from the client &#8211; 1024 bytes
$input = socket_read($client, 2024);
// Strip all white spaces from input
echo $input;
// Close the master sockets
$close = socket_close($sock);
var_dump($close);
listen();
}
set_time_limit (0);
listen();

PHP套接字侦听循环
