PHP код:

    if(text[0] == '@' && pInfo[playerid][Admin] < 1)
    {
        new str[128];
        format(str, sizeof(str), "{F781F3}(ADMIN CHAT) %s(%d): %s", PlayerName[playerid],playerid, text);
        foreach(new i : Player)
        {
            if(pInfo[playerid][Admin] > 0)
            {
                SendClientMessage(i, -1, str);
            }
        }
        return 1;
    } 


Edit: I recommend you to use ZCMD it's much easy to make commands
