Options how?

[miklosban]

    $rsync = new Rsync([
                        Rsync::CONF_EXECUTABLE => $rsync_exec,
                        Rsync::CONF_OPTIONS => [
                            Rsync::OPT_DRY_RUN,
                        ],
            ]);

I assumed this way, but this is not works. Could you help me with an example please?

I think you want

    $rsync = new Rsync([
                        Rsync::CONF_EXECUTABLE => $rsync_exec,
                        Rsync::CONF_OPTIONS => [
                            Rsync::OPT_DRY_RUN => true
                        ],
            ]);
