1，PHP端口監聽之服務器端

復制代碼 代碼示例:

// Server

// 設置錯誤處理

error_reporting(E_ALL);

// 設置運行時間

set_time_limit(0);

// 起用緩沖

ob_implicit_flush();

$ip = "127.0.0.1"; // IP地址

$port = 1000; // 端口號

$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP); // 創建一個SOCKET

if ($socket)

echo "socket_create() successed!\n";

else

echo "socket_create() failed:".socket_strerror($socket)."\n";

$bind = socket_bind($socket, $ip, $port); // 綁定一個SOCKET

if ($bind)

echo "socket_bind() successed!\n";

else

echo "socket_bind() failed:".socket_strerror($bind)."\n";

$listen = socket_listen($socket); // 間聽SOCKET

if ($listen)

echo "socket_listen() successed!\n";

else

echo "socket_listen() failed:".socket_strerror($listen)."\n";

while (true) {

$msg = socket_accept($socket); // 接受一個SOCKET

if (!$msg) {

echo "socket_accept() failed:".socket_strerror($msg)."\n";

break;

}

$welcome = "Welcome to PHP Server!\n";

socket_write($msg, $welcome, strlen($welcome));

while (true) {

$command = strtoupper(trim(socket_read($msg, 1024)));

if (!$command)

break;

switch ($command) {

case "HELLO":

$writer = "Hello Everybody!";

break;

case "QUIT":

$writer = "Bye-Bye";

break;

case "HELP":

$writer = "HELLO\tQUIT\tHELP";

break;

default:

$writer = "Error Command!";

}

socket_write($msg, $writer, strlen($writer));

if ($command == "QUIT")

break;

}

socket_close($msg);

}

socket_close($socket); // 關閉SOCKET

?>

2，php端口監聽之客戶端

復制代碼 代碼示例:

// Client

// 設置錯誤處理

error_reporting(E_ALL);

// 設置處理時間

set_time_limit(0);

$ip = "127.0.0.1"; // IP 地址

$port = 1000; // 端口號

$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP); // 創建一個SOCKET

if ($socket)

echo "socket_create() successed!\n";

else

echo "socket_create() failed:".socket_strerror($socket)."\n";

$conn = socket_connect($socket, $ip, $port); // 建立SOCKET的連接

if ($conn)

echo "Success to connection![".$ip.":".$port."]\n";

else

echo "socket_connect() failed:".socket_strerror($conn)."\n";

echo socket_read($socket, 1024);

$stdin = fopen('php://stdin', 'r');

while (true) {

$command = trim(fgets($stdin, 1024));

socket_write($socket, $command, strlen($command));

$msg = trim(socket_read($socket, 1024));

echo $msg."\n";

if ($msg == "Bye-Bye")

break;

}

fclose($stdin);

socket_close($socket);

?>
