ftp_nb_fput

(PHP 4 >= 4.3.0, PHP 5, PHP 7, PHP 8)

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);
?>

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.
