私はソケット接続の初心者です。いくつかのコマンドをソケットサーバーに送信したいのですが、他のメッセージではなく最初のメッセージしか送信できません。
クライアント:
$fp = stream_socket_client("tcp://127.0.0.1:1000", $errno, $errstr, 30);
if (!$fp) {
echo "$errstr ($errno)<br />\n";
} else {
$cmd_1 = "hello";
fwrite($fp, $cmd_1);
while (!feof($fp)) {
print_r(fgets($fp, 1024));
}
$cmd_2 = "second message";
fwrite($fp, $cmd_2);
while (!feof($fp)) {
print_r(fgets($fp, 1024));
}
fclose($fp);
}
first のように複数のメッセージを送信するにはどうすればよいですか?$cmd_1
結果によっては、送信する必要があります$cmd_2
か?
