PHP+SOCKET例子
// Client // 设置错误处理error_reporting (E_ALL);// 设置处理时间set_time_limit (0);$ip = ""; // IP 地址$port = 1000; // 端口号$socket = socket_create (AF_INET, SOCK_STREAM, SOL_TCP); // 创建一个SOCKETif ($socket) echo "socket_create() 成功!
\n";else echo "socket_create() 失败:".socket_strerror ($socket)."
\n";$conn = socket_connect ($socket, $ip, $port); // 建立SOCKET的连接if ($conn) echo "成功连接到[".$ip.":".$port."]
\n";else echo "socket_connect() 失败:".socket_strerror ($conn)."
\n";echo socket_read ($socket, 1024)."
";$stdin = fopen ('php://stdin', 'r');$ar = array("HELLO","HELP","test","QUIT");$i = 0;while (true){// $command = trim (fgets ($stdin, 1024));// socket_write ($socket, $command, strlen ($command));echo "发送 $ar[$i]
"; socket_write ($socket, $ar[$i], strlen($ar[$i]));$i++; $msg = trim (socket_read ($socket, 1024)); echo "收到:$msg
\n"; if ($msg == "Bye-Bye") break;}fclose ($stdin);socket_close ($socket);
