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

### Description

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.

### Parameters

`ftp`

  An FTP\Connection instance.

`remote_filename`

  The remote file path.

`stream`

  An open file pointer on the local file. Reading stops at end of file.

`mode`

  The transfer mode. Must be either `FTP_ASCII` or `FTP_BINARY`.

`offset`

  The position in the remote file to start uploading to.

### Return Values

Returns `FTP_FAILED` or `FTP_FINISHED` or `FTP_MOREDATA`.

### Changelog

Version | Description
--- | ---
8.1.0 | The `ftp` parameter expects an FTP\Connection instance now; previously, a resource was expected.
7.3.0 | The `mode` parameter is now optional. Formerly it has been mandatory.

### Examples

Example #1 ftp_nb_fput() example

    <?php

    $file = 'index.php';

    $fp = fopen($file, 'r');

    $ftp = ftp_connect($ftp_server);

    $login_result = ftp_login($ftp, $ftp_user_name, $ftp_user_pass);

    // Initiate the upload
    $ret = ftp_nb_fput($ftp, $file, $fp, FTP_BINARY);
    while ($ret == FTP_MOREDATA) {

       // Do whatever you want
       echo ".";

       // Continue upload...
       $ret = ftp_nb_continue($ftp);
    }
    if ($ret != FTP_FINISHED) {
       echo "There was an error uploading the file...";
       exit(1);
    }

    fclose($fp);
    ?>
