Then save the file at config/ftp.php and it will be used +automatically. + +Available connection options +**************************** + +- **hostname** - the FTP hostname. Usually something like: + ftp.example.com +- **username** - the FTP username. +- **password** - the FTP password. +- **port** - The port number. Set to 21 by default. +- **debug** - TRUE/FALSE (boolean). Whether to enable debugging to + display error messages. +- **passive** - TRUE/FALSE (boolean). Whether to use passive mode. + Passive is set automatically by default. + +$this->ftp->upload() +==================== + +Uploads a file to your server. You must supply the local path and the +remote path, and you can optionally set the mode and permissions. +Example:: + + $this->ftp->upload('/local/path/to/myfile.html', '/public_html/myfile.html', 'ascii', 0775); + +**Mode options are:** ascii, binary, and auto (the default). If auto is +used it will base the mode on the file extension of the source file. + +Permissions are available if you are running PHP 5 and can be passed as +an octal value in the fourth parameter. + +$this->ftp->download() +====================== + +Downloads a file from your server. You must supply the remote path and +the local path, and you can optionally set the mode. Example:: + + $this->ftp->download('/public_html/myfile.html', '/local/path/to/myfile.html', 'ascii'); + +**Mode options are:** ascii, binary, and auto (the default). If auto is +used it will base the mode on the file extension of the source file. + +Returns FALSE if the download does not execute successfully (including +if PHP does not have permission to write the local file) + +$this->ftp->rename() +==================== + +Permits you to rename a file.

Supply the source path with the file name. + +:: + + $this->ftp->delete_file('/public_html/joe/blog.html'); + +$this->ftp->delete_dir() +========================= + +Lets you delete a directory and everything it contains. Supply the +source path to the directory with a trailing slash. + +**Important** Be VERY careful with this function. It will recursively +delete **everything** within the supplied path, including sub-folders +and all files. Make absolutely sure your path is correct. Try using the +list_files() function first to verify that your path is correct. + +:: + + $this->ftp->delete_dir('/public_html/path/to/folder/'); + +$this->ftp->list_files() +========================= + +Permits you to retrieve a list of files on your server returned as an +array. You must supply the path to the desired directory. + +:: + + $list = $this->ftp->list_files('/public_html/'); print_r($list); + +$this->ftp->mirror() +==================== + +Recursively reads a local folder and everything it contains (including +sub-folders) and creates a mirror via FTP based on it. Whatever the +directory structure of the original file path will be recreated on the +server. You must supply a source path and a destination path:: + + $this->ftp->mirror('/path/to/myfolder/', '/public_html/myfolder/'); + +$this->ftp->mkdir() +=================== + +Lets you create a directory on your server. Supply the path ending in +the folder name you wish to create, with a trailing slash. Permissions +can be set by passed an octal value in the second parameter (if you are +running PHP 5). + +:: + + // Creates a folder named "bar" $this->ftp->mkdir('/public_html/foo/bar/', DIR_WRITE_MODE); + +$this->ftp->chmod() +=================== + +Permits you to set file permissions.
