PHP 5.4.33 Released

ftp_nb_fput

(PHP 4 >= 4.3.0, PHP 5)

ftp_nb_fputStores 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 = 0 ] )

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

The position in the remote file to start uploading to.

Return Values

Returns FTP_FAILED or FTP_FINISHED or FTP_MOREDATA.

Examples

Example #1 ftp_nb_fput() example

<?php

$file 
'index.php';

$fp fopen($file'r');

$conn_id ftp_connect($ftp_server);

$login_result ftp_login($conn_id$ftp_user_name$ftp_user_pass);

// Initate the upload
$ret ftp_nb_fput($conn_id$file$fpFTP_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);
}

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.
