Сокеты б*я
Пол дня с ними долбаюсь
Короче говоря есть сервер и клиент
код сервера:
Цитата:
<?
header('Content-Type: text/plain;');
error_reporting(E_ALL ^ E_WARNING);
set_time_limit(0);
ob_implicit_flush();
echo "-= Server =-\n\n";
$address = 'localhost';
$port = 123;
try {
echo 'Create socket ... ';
if (($sock = socket_create(AF_INET, SOCK_STREAM, SOL_TCP)) < 0) {
throw new Exception('socket_create() failed: '.socket_strerror(socket_last_error())."\n");
} else {
echo "OK\n";
}
echo 'Bind socket ... ';
if (($ret = socket_bind($sock, $address, $port)) < 0) {
throw new Exception('socket_bind() failed: '.socket_strerror(socket_last_error())."\n");
} else {
echo "OK\n";
}
echo 'Listen socket ... ';
if (($ret = socket_listen($sock, 5)) < 0) {
throw new Exception('socket_listen() failed: '.socket_strerror(socket_last_error())."\n");
} else {
echo "OK\n";
}
do {
echo 'Accept socket ... ';
if (($msgsock = socket_accept($sock)) < 0) {
throw new Exception('socket_accept() failed: '.socket_strerror(socket_last_error())."\n");
} else {
echo "OK\n";
}
$msg = "Hello, Client!";
echo "Say to client ($msg) ... ";
socket_write($msgsock, $msg, strlen($msg));
echo "OK\n";
do {
echo 'Client said: ';
if (false === ($buf = socket_read($msgsock, 1024))) {
throw new Exception('socket_read() failed: '.socket_strerror(socket_last_error())."\n");
} else {
echo $buf."\n";
}
echo "Say to client ($buf) ... ";
socket_write($msgsock, $buf, strlen($buf));
echo "OK\n";
} while (true);
} while (true);
} catch (Exception $e) {
echo "\nError: ".$e->getMessage();
}
if (isset($sock)) {
echo 'Close socket ... ';
socket_close($sock);
echo "OK\n";
}
?>

код клиента:
Цитата:
<?
header('Content-Type: text/plain;');
error_reporting(E_ALL ^ E_WARNING);
set_time_limit(0);
ob_implicit_flush();
echo "-= Client =-\n\n";
$address = 'localhost';
$port = 123;
try {
echo 'Create socket ... ';
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
if ($socket < 0) {
throw new Exception('socket_create() failed: '.socket_strerror(socket_last_error())."\n");
} else {
echo "OK\n";
}
echo 'Connect socket ... ';
$result = socket_connect($socket, $address,$port);
if ($result === false) {
throw new Exception('socket_connect() failed: '.socket_strerror(socket_last_error())."\n");
} else {
echo "OK\n";
}
echo 'Server said: ';
$out = socket_read($socket, 1024);
echo $out."\n";
$msg = "Hello, Server!";
echo "Say to server ($msg) ...";
socket_write($socket, $msg, strlen($msg));
echo "OK\n";
echo 'Server said: ';
$out = socket_read($socket, 1024);
echo $out."\n";
$msg = 'shutdown';
echo "Say to server ($msg) ... ";
socket_write($socket, $msg, strlen($msg));
echo "OK\n";
} catch (Exception $e) {
echo "\nError: ".$e->getMessage();
}
if (isset($socket)) {
echo 'Close socket ... ';
socket_close($socket);
echo "OK\n";
}
?>

Случай 1: $address="localhost", $port = 123
-= Client =-
Create socket ... OK
Connect socket ... OK
Server said: Hello, Client!
Say to server (Hello, Server!) ...OK
Server said: Hello, Server!
Say to server (shutdown) ... OK
Close socket ... OK
-= Server =-
Create socket ... OK
Bind socket ... OK
Listen socket ... OK
Accept socket ... OK
Say to client (Hello, Client!) ... OK
Client said: Hello, Server!
Say to client (Hello, Server!) ... OK
Client said: shutdown
Say to client (shutdown) ... OK
Client said:
Error: socket_read() failed: Удаленный хост принудительно разорвал существующее подключение.
Close socket ... OK
Случай 2: $address="ХХХ", $port = 123 (оба файла залил на сервер ХХХ)
-= Server =-
страница не открывается (т.к. страница постояяно пополняется строками "Client said:" и "Say to client "
-= Client =-
Create socket ... OK
Connect socket ...
Error: socket_connect() failed: Connection refused
Close socket ... OK
Помогите устранить глупую проблему |
