我在php中使用套接字编写了一个脚本，一个文件是服务器而另一个是客户端。
这是我的服务器文件（server.php），我使用命令＆＃34; php -q server.php 192.168.15.3 8959＆＃34;在服务器linux上。

这是我的客户档案＆＃34; send.php＆＃34; 当我在浏览器http://192.168.15.3/send.php上使用时 这给我发了消息＆＃34; Socket conneted 192.168.15.3：8959 消息正确发送1＆＃34 ;;
但是在server.php中告诉我
PHP Warning: socket_getpeername(): unable to retrieve peer name [107]:
Transport endpoint is not connected in /var/www/html/panel/server.php on line 48

我的文件send.php很简单..
$date = new DateTime();
$arrayRetorno = array(
'type' =>'usermsg',
'guiche' => '3',
'setor' => '1',
'sigla' => 'AT',
'senha' => '20',

'tipo' => 'Tipo',
'servico'=> 'Servico',
'data' => $date->format('d-m-Y H:i:s'),
'hora' => $date->format('H:i:s')
);

/* Allow the script to hang around waiting for connections. */

/* Turn on implicit output flushing so we see what we're getting

ob_implicit_flush();
/* Get the port for the WWW service. */
$service_port = '8959';
/* Get the IP address for the target host. */
$address = '192.168.15.3';
$socket = socket_create(AF_INET,SOCK_STREAM,SOL_TCP);
$result = socket_connect($socket, $address, $service_port);
if ($result === false) {
echo "socket_connect() failed.\nReason: ($result) " .
socket_strerror(socket_last_error($socket)) . "\n";
} else echo "Socket conneted $address: $service_port <br >";
if (socket_bind($socket, $address, $service_port)) {
echo "Socket bound correctly";
}
$buf = 'Test Message';
$len = strlen($buf);
if (socket_sendto($socket, $buf, $len, 0x100, $address, $service_port) !== FALSE) {
echo "Message sent correctly";
}
socket_sendmsg ( $socket , $arrayRetorno );
有人可以帮助我吗？
