Yes you need to check for INVALID_PLAYER_ID

PHP код:

CMD:id(playerid, params[]) 
{ 
    new id, string[144]; 
    if(sscanf(params, "u", id)) 
        return SendClientMessage(playerid, COLOR_RED,"Use: /id [Nume/ID]"); 
    if(id != INVALID_PLAYER_ID)
    {
        format(string, sizeof(string), "Name:%s(%i) | Scor:%i | Class:%s | Admin:%i | VIP:%i", pName(id), id,APlayerData[id][PlayerScore], GetPlayerClassEx(id), APlayerData[id][PlayerLevel], APlayerData[id][VPlayerLevel]); 
        SendClientMessage(playerid, Grey, string); 
    }
    else 
        return SendClientMessage(playerid, COLOR_RED, "Error: Invalid PlayerID/PlayerName.");
    return 1; 
}
