Phpftp file upload function (Basic edition)

For many times, we will not use phpftp function file upload, but some advanced WEB applications will use ftp functions. for example, if I want to transfer uploaded images to server B, data is stored on server A. normal PHP files cannot be uploaded, but ftp functions can be used. The code is as follows:
// Define variables
$ Local_file = 'local.zip ';
$ Server_file = 'server.zip ';
// Connect to the FTP server
$ Conn_id = ftp_connect ($ ftp_server );
// Verify the login server
$ Login_result = ftp_login ($ conn_id, $ ftp_user_name, $ ftp_user_pass );
// Download an object
If (ftp_get ($ conn_id, $ local_file, $ server_file, FTP_BINARY )){
Echo "Download $ local_file succeeded n ";
} Else {
Echo "Download failed n ";
}
// Close the ftp connection
Ftp_close ($ conn_id );
?>

Ftp_connect-create a new FTP connection
Ftp_login-log on to the FTP server
Ftp_get-download an object from the FTP server
