问如何在php中使用fopen打开ftps路径；未收到来自的标识字符串

EN

Did not receive identification string from xxx.xxx.xxx.xxx

Warning: fopen() failed to open stream.

$ftp_path = "ftps://user:password@remoteaddress:12345/path/to/file/filename.txt";//port 12345 is deliberate because I use port forwarding on the server to reduce failed hack attempts

$ftp_path = "ftps://user:password@remoteaddress:12345/path/to/file/filename.txt";
// Allow/disallow overwriting of existing files on the remote FTP server
$stream_options = array('ftps' => array('overwrite' => false));
// Creates a stream context resource with the defined options
$stream_context = stream_context_create($stream_options);
// Opens the file for writing and truncates it to zero length 
if ($fh = fopen($ftp_path, 'w', 0, $stream_context)){
    // Writes contents to the file
    if(fputs($fh, $content)){
        echo "records pushed successfully.";
    } else {
        echo "The stream was opened, but the records failed to push.";
    }
    // Closes the file handle
    fclose($fh);
} else {
    die('Could not open remote ftp.');
}
