ftp_nb_put

PHP function Edit on GitHub ✎

(PHP 4 >= 4.3.0, PHP 5, PHP 7, PHP 8)

Stores a file on the FTP server (non-blocking)

Description

ftp_nb_put(FTP\Connection $ftp, string $remote_filename, string $local_filename, int $mode = FTP_BINARY, int $offset = 0): int|false

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.

Parameters

ftp: Ftp
remote_filename: The remote file path.
local_filename: The local file path.
mode: The transfer mode. Must be either FTP_ASCII or FTP_BINARY.
offset: The position in the remote file to start uploading to.

Return Values

Returns FTP_FAILED or FTP_FINISHED or FTP_MOREDATA, or false on failure to open the local file.

Changelog

Version	Description
7.3.0	The `mode` parameter is now optional. Formerly it has been mandatory.
