(PHP 4 >= 4.3.0, PHP 5, PHP 7)
Retrieves a file from the FTP server and writes it to an open file (non-blocking)
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.
Returns:
Returns FTP_FAILED
or FTP_FINISHED
or FTP_MOREDATA
.
Examples:
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); ?>
