PHP код:

aR(playerid)
{
    new ranks[555];
    if(GetPlayerScore(playerid) => 10 && GetPlayerScore(playerid) =< 19) ranks = "Level 1";
    if(GetPlayerScore(playerid) => 20 && GetPlayerScore(playerid) =< 39) ranks = "Level 2";
    if(GetPlayerScore(playerid) => 40 && GetPlayerScore(playerid) =< 69) ranks = "Level 3";
    if(GetPlayerScore(playerid) >= 70) ranks = "Level 4";
    return ranks;
} 


This is an example of it. Change the Level names. And also go in the same pattern for more ranks.
