Here it is:

You need "zcmd" include and "sscanf2" include.
Also sscanf plugin.

PHP код:

CMD:n(playerid, params[])
{
    new msg[128], result[128];
    if(sscanf(params,"s[128]", result)) return SendClientMessage(playerid, -1, "USAGE: /n [text]");
    new pName[MAX_PLAYER_NAME];
    GetPlayerName(playerid, pName, sizeof(pName));//    )
    format(msg, sizeof(msg), "[NEWBIE]: %s - %s", pName, result);//pName
    SendClientMessageToAll(COLOR_LIME, msg);
    return 1;
}
