不中啊
$str='\xFA\x01\x01' 以这种形式发送,显示的是 5C 78 46 41 5C 78 30 31 5C 78 30 31 $str=\xFA\x01\x01 php直接报错唉
那我该如何处理呢 可以accept多次?
$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");
}
这是我的代码
