sockets模拟通讯
服务器端：
1 //创建服务器端 2 $socket = socket_create(AF_INET,SOCK_STREAM,SOL_TCP); 3 4 //设置配置 - 设置套流的最大超时时间1秒 5 socket_set_option($socket,SOL_SOCKET, SO_RCVTIMEO, array('sec'=>1, 'usec'=>0)); 6 socket_set_option($socket, SOL_SOCKET, SO_RCVTIMEO, array('sec'=>6, 'usec'=>0)); 7 $host_ip = 'localhost'; 8 $host_port = '83'; 9 //连接服务器套件 10 if(socket_connect($socket, $host_ip, $host_port) == false){ 11 echo 'service bind fail:'.socket_strerror(socket_last_error()); 12 }else{ 13 //发送命令 14 $in = "HEAD / HTTP/1.1\r\n"; 15 $in .= "Connection: Close\r\n\r\n"; 16 $out = ''; 17 echo "Send Command.........."; 18 $in = "sun\n"; 19 socket_write($socket, $in, strlen($in)); 20 echo "OK.\n"; 21 echo "Reading Backinformatin:\n\n"; 22 while ($out = socket_read($socket, 2048)) { 23 echo $out; 24 } 25 echo "Close socket........"; 26 socket_close($socket); 27 echo "OK,He He.\n\n"; 28 29 }
客户端：
