Question

I have a working FTP file download script.
The files I am downloading will be about 2-4 GB per day.
I was wondering if there was a way to get the percent of the file where it’s at?

I have looked on php.net and on here but I couldn’t find any similar questions and rather spend more time looking I figure I would ask people much smarter than myself.

I was thinking about if there was a function to see where it’s at in the download, but I couldn’t find one since ftp_get would have to complete first so that eliminated the chance of flushing the buffer every few seconds to display a new percent.

Anyone?

Here is my code: I hid all of my variables above it.

$conn_id = ftp_connect($ftp_server);

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

if (ftp_get($conn_id, $local_file, $server_file, FTP_BINARY)) {
    echo "Successfully written to $local_file\n";
} else {
    echo "There was a problem\n";
}

ftp_close($conn_id);

EDIT:

I added ftp_nb_get and here is my code for that. It keeps downloading fine, just doesn’t echo it out to the browser.

$ret = ftp_nb_get($conn_id, $local_file, $server_file, FTP_BINARY, $size);
while ($ret == FTP_MOREDATA) {
  echo round((filesize($local_file)/$server_size)*100)."%\n";
  $ret = ftp_nb_continue($conn_id);
}

Try using the non-blocking version ftp_nb_get() and ftp_nb_continue() in a loop, and check for the saved file’s size.
