最近在php下做关于Socket通讯的相关内容,发现网络上好多人在了解如何进行16进制收发,研究了下,代码如下,欢迎拍砖。
复制代码 代码如下:
        $sendStr = '30 32 30 34 03 30 33';  // 16进制数据

        $sendStrArray = str_split(str_replace(' ', '', $sendStr), 2);  // 将16进制数据转换成两个一组的数组

        $socket = socket_create(AF_INET, SOCK_STREAM, getprotobyname("tcp"));  // 创建Socket

        if (socket_connect($socket, "192.168.1.100", 8080)) {  //连接
            for ($j = 0; $j                 socket_write($socket, chr(hexdec($sendStrArray[$j])));  // 逐组数据发送
            }

            $receiveStr = "";
            $receiveStr = socket_read($socket, 1024, PHP_BINARY_READ);  // 采用2进制方式接收数据
            $receiveStrHex = bin2hex($receiveStr);  // 将2进制数据转换成16进制

            echo "client:" . $receiveStrHex;
        }
        socket_close($socket);  // 关闭Socket
        ?>
