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.
ftp_nb_fput
(PHP 4 >= 4.3.0, PHP 5, PHP 7)
ftp_nb_fput — Stores a file from an open file to the FTP server (non-blocking)
Descrierea
ftp_nb_fput

, string $remote_file
, resource $handle
, int $mode = FTP_BINARY
, int $startpos = 0
) : intftp_nb_fput() uploads the data from a file pointer to a remote file on the FTP server.
