UDP写入套接字并同时从套接字读取(再次进行修改)
服务器:
<?php
error_reporting(E_ALL | E_STRICT);
$socket = socket_create(AF_INET, SOCK_DGRAM, SOL_UDP);
socket_bind($socket, '192.168.1.7', 11104);
$from = "";
$port = 0;
socket_recvfrom($socket, $buf, 12, 0, $from, $port);
//$buf=socket_read($socket, 2048);
echo "Received $buf from remote address $from and remote port $port" . PHP_EOL;
$msg="Sikerult";
//socket_write($socket, $msg, strlen($msg));
socket_sendto($socket, $msg, strlen($msg), 0, '192.168.1.6', 11105);
//socket_close($socket);
?>
客户端:
<?php
$sock = socket_create(AF_INET, SOCK_DGRAM, SOL_UDP);
$result = socket_connect($sock, '192.168.1.6', 11105);
$msg = "Sikerult";
$len = strlen($msg);
//socket_write($sock, $msg, strlen($msg));
socket_sendto($sock, $msg, $len, 0, '192.168.1.7', 11104);
//$buf=socket_read($sock, 2048);
socket_recvfrom($sock, $buf, 12, 0, $from, $port);
echo $buf;
socket_close($sock);
?>
服务器从客户端接收数据,但客户端没有从服务器收到任何数据,并且不停止运行。
Server:
<?php
error_reporting(E_ALL | E_STRICT);
$socket = socket_create(AF_INET, SOCK_DGRAM, SOL_UDP);
socket_bind($socket, '192.168.1.7', 11104);
$from = "";
$port = 0;
socket_recvfrom($socket, $buf, 12, 0, $from, $port);
//$buf=socket_read($socket, 2048);
echo "Received $buf from remote address $from and remote port $port" . PHP_EOL;
$msg="Sikerult";
//socket_write($socket, $msg, strlen($msg));
socket_sendto($socket, $msg, strlen($msg), 0, '192.168.1.6', 11105);
//socket_close($socket);
?>
Client:
<?php
$sock = socket_create(AF_INET, SOCK_DGRAM, SOL_UDP);
$result = socket_connect($sock, '192.168.1.6', 11105);
$msg = "Sikerult";
$len = strlen($msg);
//socket_write($sock, $msg, strlen($msg));
socket_sendto($sock, $msg, $len, 0, '192.168.1.7', 11104);
//$buf=socket_read($sock, 2048);
socket_recvfrom($sock, $buf, 12, 0, $from, $port);
echo $buf;
socket_close($sock);
?>
The server receives the data from the client but the client got nothing from the server and not stop running.

如果它是 UDP 套接字,那么为什么首先需要连接。 这还不够吗?
If it is a UDP socket then why do you need to connect in the first place. Doesn't this suffice?
我假设
192.168.1.7:11104
是您的服务器。在服务器中,您需要将数据包发送回接收它的位置:
在客户端中,您要连接到自身。 您应该将其连接到服务器:
I'm assuming that
192.168.1.7:11104
is your server.In server you need to send packet back to where you've received it from:
In the client you're connecting to itself. You should connect it to server:
