Question

我需要创建Java套接字客户端和PHP-cli套接字服务器，并且需要向客户端发送一个UTF-8编码的字节数组，并使Java BufferedInputStream.read（）函数接受它。

[SERVER]

$input = socket_read($client[$i]['sock'],1024,PHP_BINARY_READ);
if($input==null || $input===FALSE) {unset($client[$i]);}
socket_write($client[$i]['sock'], unpack('C*', utf8_encode($input)));

[CLIENT]

out = new BufferedOutputStream(socket.getOutputStream());
out.write(str.getBytes("UTF-8"));
out.flush();

in = new BufferedInputStream(socket.getInputStream());
byte[] b = new byte[]{};
str = new String(in.read(b), "UTF-8");
System.out.println("[SOCKET] Server: " + str);

所以我需要PHP的类比 String.getBytes("UTF-8");
感谢您的反馈！

更改输入流。这解决了我的问题。尝试更改规则：

in = new BufferedInputStream(socket.getInputStream());

要：

in = new BufferedReader(new InputStreamReader(socket.getInputStream(), "UTF-8"));

在PHP端，您可以使用utf8_encode将String编码为UTF-8。 E.g。

$message = utf8_encode($message);
if ( ($fp = fsockopen($host, $port, $errno, $errstr, 3) ) === FALSE)
    echo "$errstr ($errno)";
else {
    print 'SUCCESS!<br />';
    fwrite($fp, $message);

如何在PHP中为Java BufferedInputStream.read（）将字符串转换为UTF-8字节数组？
