ftp_nb_fget

Description

int ftp_nb_fget ( resource ftp_stream, resource handle, string remote_file, int mode [, int resumepos])

ftp_nb_fget() retrieves remote_file from the FTP server, and writes it to the given file pointer, handle. The transfer mode specified must be either FTP_ASCII or FTP_BINARY. The difference between this function and the ftp_fget() is that this function retrieves the file asynchronously, so your program can perform other operations while the file is being downloaded.

Example 1. ftp_nb_fget() example <?php // open some file for reading $file = 'index.php'; $fp = fopen($file, 'w'); $conn_id = ftp_connect($ftp_server); $login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass); // Initate the download $ret = ftp_nb_fget($conn_id, $fp, $file, FTP_BINARY); while ($ret == FTP_MOREDATA) {    // Do whatever you want    echo ".";    // Continue downloading...    $ret = ftp_nb_continue($conn_id); } if ($ret != FTP_FINISHED) {    echo "There was an error downloading the file...";    exit(1); } // close filepointer fclose($fp); ?>

Returns FTP_FAILED, FTP_FINISHED, or FTP_MOREDATA.
