PHP ftp_nb_fget() function
Definition and Usage
The ftp_nb_fget() function downloads a file from the FTP server and saves it to a locally opened file (non-blocking).
The function returns the following values:
- FTP_FAILED (send/receive failed)
- FTP_FINISHED (send/receive completed)
- FTP_MOREDATA (send/receive in progress)
With ftp_fget() Different, this function fetches the file asynchronously. This means that your program can perform other operations while the file is being downloaded.
