php如何同时处理多个任务(关于php socket)
我现在要写一个socket监听一个端口,如果有数据过来,开始while循环,现在问题出来了,同时只能有一个客户端连接这个服务端,有第二个连接时,就连接不上,有的朋友说就accept了一次,但是应该如何修改呢?下面贴上我的代码,请会的朋友指导下(说详细点,最好可以帮我修改下代码)



PHP code
$commonProtocol = getprotobyname("tcp");$socket = socket_create(AF_INET, SOCK_STREAM, $commonProtocol);@socket_bind($socket, '192.168.1.202', 8888);@socket_listen($socket);// Initialize the buffer$buffer = "NO DATA";while(true){sleep(1);     // Accept any connections coming in on this socket $connection = @socket_accept($socket); printf("Socket connected\r\n"); // Check to see if there is anything in the buffer if($buffer != "") {  printf("Something is in the buffer...sending data...\r\n");  @socket_write($connection, $buffer . "\r\n");  printf("Wrote to socket\r\n"); } else {  printf("No Data in the buffer\r\n"); } // Get the input while($data = @socket_read($connection, 14, PHP_NORMAL_READ)) {          if (!empty($data)){         $buffer = $data;   //文件驱动模式       /*$f = fopen(dirname(__FILE__).'/file/'.date('YmdHis').'.txt','w');    fwrite($f,$buffer);     fclose($f); */     socket_set_nonblock($connection);   socket_getpeername($connection,&$remoteIP,&$remotePort);echo $remoteIP."\r\n";echo $remotePort."\r\n";    $data=str_split($buffer);  print_r($data);  foreach($data as $v){     echo dechex(ord($v))."\t";     } echo "\r\n";      }     } @socket_close($connection); printf("Closed the socket\r\n\r\n");  }
