(PHP 4 >= 4.3.0, PHP 5, PHP 7)
ftp_nb_put — Stores a file on the FTP server (non-blocking)
ftp_nb_put ( resource $ftp_stream , string $remote_file , string $local_file [, int $mode = FTP_BINARY [, int $startpos = 0 ]] ) : int
ftp_nb_put() stores a local file on the FTP server.
The difference between this function and the ftp_put() is that this function uploads the file asynchronously, so your program can perform other operations while the file is being uploaded.
ftp_stream
The link identifier of the FTP connection.
remote_file
The remote file path.
local_file
The local file path.
mode
The transfer mode. Must be either FTP_ASCII or FTP_BINARY.
startpos
The position in the remote file to start uploading to.
Returns FTP_FAILED or FTP_FINISHED or FTP_MOREDATA.
| Version | Description |
|---|---|
| 7.3.0 | The mode parameter is now optional. Formerly it has been mandatory. |
