# ftp_nb_fput

(PHP 4 >= 4.3.0, PHP 5)

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

### Description

int ftp_nb_fput ( resource `$ftp_stream` , string `$remote_file` , resource `$handle` , int `$mode` [, int `$startpos` ] )

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_stream`

  The link identifier of the FTP connection.

`remote_file`

  The remote file path.

`handle`

  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`.

`startpos`

### Return Values

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

### Examples

$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);
// Initate the upload
$ret = ftp_nb_fput($conn_id, $file, $fp, FTP_BINARY);
while ($ret == FTP_MOREDATA) {
// Do whatever you want
echo ".";
// Continue upload...
$ret = ftp_nb_continue($conn_id);
}
if ($ret != FTP_FINISHED) {
echo "There was an error uploading the file...";
exit(1);
}
