ソケット tcp php サーバー
サーバー側のコードは次のとおりです:<?phpset_time_limit(0); $host = "127.0.0.1";$port = 12345; $socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP) or die("Could not create socket\n"); // 创建一个Socket $result = socket_bind($socket, $host, $port) or die("Could not bind tosocket\n"); //绑定Socket到端口 $result = socket_listen($socket) or die("Could not set up socket listener\n"); // 开始监听连接 $spawn = socket_accept($socket) or die("Could not accept incoming connection\n"); // 处理通信//若换成循环接收数据,客户端将一直处理等待接收状态$input = socket_read($spawn, 1024) or die("Could not read data\n");/* while (( $data = socket_read($spawn, 1024)) != false) $input .= $data;*/ echo 'input:', strlen($input), "\n"; $output = date("Y-m-d H:i:s").
