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获得任何内容,也没有停止运行。

如果它是UDP套接字,那么为什么首先需要连接。这不够吗?
<?php
$sock = socket_create(AF_INET, SOCK_DGRAM, SOL_UDP);
$msg = "Sikerult";
$len = strlen($msg);
socket_sendto($sock, $msg, $len, 0, '192.168.1.7', 11104);
socket_recvfrom($sock, $buf, 12, 0, '192.168.1.7', 11104);
echo $buf;
socket_close($sock);
?>

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您收到的地址:
//...
$msg="Sikerult";
//...
socket_sendto($socket, $msg, strlen($msg), 0, $from, $port);
在客户端,你正在连接自己。您应该将它连接到服务器:
$srvIP = '192.168.1.7';
$srvPort = 11104;
$result = socket_connect($sock, $srvIP, $srvPort);
$msg = "Sikerult";
$len = strlen($msg);
socket_send($sock, $msg, $len, 0);
socket_recv($sock, $buf, 12, 0);
