    ftp_nb_fput — Stores a file from an open file to the FTP server (non-blocking)

    Опис

    ftp_nb_fput(
        FTP\Connection $ftp,
        string $remote_filename,
        resource $stream,
        int $mode = FTP_BINARY,
        int $offset = 0
    ): int

    ftp_nb_fput() uploads the data from a file pointer to a remote file on the FTP server.

    The difference between this function and the ftp_fput() is that this function uploads the file asynchronously, so your program can perform other operations while the file is being uploaded.

    There is an easy way to check progress while uploading a file. Just use the ftell function to watch the position in the file handle. ftp_nb_fput will increment the position as the file is transferred.

    Example:

    <?

    $fh = fopen ($file_name, "r");
    $ret = ftp_nb_fput ($ftp, $file_name, $fh, FTP_BINARY);
    while ($ret == FTP_MOREDATA) {
    print ftell ($fh)."\n";
    $ret = ftp_nb_continue($ftp);
    }
    if ($ret != FTP_FINISHED) {
    print ("error uploading\n");
    exit(1);
    }
    fclose($fh);

    ?>

    This will print out the number of bytes transferred thus far, every time the loop runs. Coverting this into a percentage is simply a matter of dividing the number of bytes transferred by the total size of the file.
