PHP код:

CMD:findhouse(playerid, params[])
{
    new houseid;
    if(sscanf(params,"i",houseid)) return SendClientMessage(playerid, -1, "Use: /findhouse [id]");
    SetPlayerCheckpoint(playerid, HouseInfo[houseid][hPosX], HouseInfo[houseid][hPosY], HouseInfo[houseid][hPosZ] , 5.0)
    return 1;
} 


you can improve your order if you need to display something else.
it's not tested.
