PHP код:

    new MaxKills;
    new HighestPlayerID;
    for(new i=0; i < MAX_PLAYERS; i++)
    {
        if (/*Player's kills*/ > MaxKills)
        {
            HighestPlayerID = i;
            MaxKills = /*Player's Kills*/;
        }
    }
    new string[72];
    format(string, sizeof(string), "ID:%d with %d Kills", HighestPlayerID, MaxKills);
    SendClientMessage(playerid, -1, string); 


You'll have to replace the commented variables.
