ftp_nb_fget

(PHP 4 >= 4.3.0, PHP 5)

ftp_nb_fgetRetrieves a file from the FTP server and writes it to an open file (non-blocking)

Description

int ftp_nb_fget ( resource $ftp_stream , resource $handle , string $remote_file , int $mode [, int $resumepos = 0 ] )

ftp_nb_fget() retrieves a remote file from the FTP server.

The difference between this function and ftp_fget() is that this function retrieves the file asynchronously, so your program can perform other operations while the file is being downloaded.

Parameters

ftp_stream

The link identifier of the FTP connection.

handle

An open file pointer in which we store the data.

remote_file

The remote file path.

mode

The transfer mode. Must be either FTP_ASCII or FTP_BINARY.

resumepos

The position in the remote file to start downloading from.

Return Values

Returns FTP_FAILED or FTP_FINISHED or FTP_MOREDATA.

Examples

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

// Initate the download
$ret ftp_nb_fget($conn_id$fp$fileFTP_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);
?>
