[Unknown123]

Can someone remake this? it bugs my MySQL things..
And when my brother(Abc123) connect it says Unknown123

pawn Код:

public OnPlayerConnect(playerid)
{
    new servername[25], string[128];
    GetServerVarAsString("hostname", servername, sizeof(servername));
    for(new i = 0; i < MAX_PLAYERS; i++)
    {
        if(IsPlayerAdmin(i) || PlayerData[i][AdminLevel] > 1)
        {
            format(string, sizeof(string), "%s(%d) Has Joined %s. (IP: %s)", PlayerName(i), i, servername, PlayerIP(i));
            SendClientMessage(i, COLOR_GREY, string);
            SendDeathMessage(playerid, INVALID_PLAYER_ID, 200);
            return 1;
        }
        else
        {
            format(string, sizeof(string), "%s(%d) Has Joined %s.", PlayerName(i), i, servername);
            SendClientMessage(i, COLOR_GREY, string);
            SendDeathMessage(playerid, INVALID_PLAYER_ID, 200);
            return 1;
        }
    }
}

Extra:

pawn Код:

stock PlayerName(playerid)
{
    new name[MAX_PLAYER_NAME];
    GetPlayerName(playerid, name, sizeof(name));
    return name;
}
