PHP код:

CMD:giverank(playerid, params[])
{
    if(pInfo[playerid][pAdmin] < 1) return SendClientMessage(playerid, -1, "You are not authorized to use that command!");
    new giveplayerid, rank;
    if(sscanf(params, "ud", giveplayerid, rank)) return SendClientMessage(playerid, -1, "USAGE: /giverank [playerid] [Rank (1-2)]");
    if(!IsPlayerConnected(giveplayerid)) return SendClientMessage(playerid, -1, "There is no such player!");
    switch(rank)
    {
        case 1: pInfo[giveplayerid][pMod] = 1;
        case 2..6: pInfo[giveplayerid][pAdmin] = rank - 1;
        default: SendClientMessage(playerid, -1, "Don't go below number 0, or above number 6!");
    }
    return 1;
} 


'rank' is not a string or array in this instance, so it doesn't need you to specify a size. It is an integer and can be a standalone variable.

I'm assuming pAdmin is increased when a number above 1 is entered, so this is the code I've given you. Please change accordingly.
