Complete PHP FTP Reference
Definition and Usage
The ftp_nb_continue() function continues to receive/send a file to the FTP server.
This function returns one of the following values:
- FTP_FAILED (send/receive failed)
- FTP_FINISHED (send/receive completed)
- FTP_MOREDATA (send/receive in progress)
This function sends/retrieves the file asynchronously. This means your program can perform other operations while the file is being downloaded.
Syntax
