PHP код:

CMD:engine(playerid, params[])
{
    #define charsmax(%1) sizeof(%1)-1
    
    if(GetPlayerState(playerid) == PLAYER_STATE_DRIVER)
    {
        new tmp, bEngine, vehicleid = GetPlayerVehicleID(playerid);
        GetVehicleParamsEx(vehicleid, bEngine, tmp, tmp, tmp, tmp, tmp, tmp);
       
        new bState = (bEngine == VEHICLE_PARAMS_OFF || bEngine == VEHICLE_PARAMS_UNSET);
        SetVehicleParamsEx(vehicleid, bState, bState, -1, -1, -1, -1, -1);
       
        new string[64];
        GetPlayerName(playerid, string, charsmax(string));
        format(string, charsmax(string), "* %s turn the ignition and %s the engine.", string, bState ? ("starts") : ("turns off"));
        
        SendNearbyMessage(playerid, 15, string, COLOR_PURPLE, COLOR_PURPLE, COLOR_PURPLE, COLOR_PURPLE, COLOR_PURPLE)       
    }
    return 1;
} 


Use this code. It don't need any extra variables.
