I use this

pawn Код:

stock GetStringText(const string[],idx,text[256])
{
    new length = strlen(string);
    while ((idx < length) && (string[idx] <= ' ')) { idx++; }
    new offset = idx; new result[256];
    while ((idx < length) && ((idx - offset) < (sizeof(result) - 1))) { result[idx - offset] = string[idx]; idx++; }
    result[idx - offset] = EOS;
    text = result;
    return result;
}

in cmd make

pawn Код:

new text[256];

than put this in place where you usual use strtok to get some value etc

pawn Код:

GetStringText(params,idx,text);

EDIT: whole cmd

pawn Код:

dcmd_kick(playerid,params[])
{
    new n[MAX_PLAYER_NAME],on[MAX_PLAYER_NAME];
    new tmp[32], Index, string[128];
    tmp = strtok(params,Index);
    if(!strlen(tmp))
    {
        SendClientMessage(playerid,GREY,"USAGE: /kick <ID> [reason]"); return 1;
    }
    new id = strval(tmp);
    if(PInfo[playerid][Level] < 3)
    {
        SendClientMessage(playerid,ORANGE,"You need to be level 3 to use this command!"); return 1;
    }
    if(IsPlayerConnected(id))
    {
        GetPlayerName(id,on,sizeof(on));
        GetPlayerName(playerid,n,sizeof(n));
        new text[256];
        GetStringText(params,Index,text);
        if(!strlen(text))
        {
            SendClientMessage(playerid,GREY,"USAGE: /kick <ID> [reason]"); return 1;
        }
        format(string,sizeof(string),"Administrator %s has kicked %s Reason: %s",n,on,text);
        SendClientMessageToAll(0xFF0000FF,string);
        Kick(id);
        return 1;
    }
    else
    {
        SendClientMessage(playerid,GREY,"Invalid ID");
    }
    return 1;
}

check things like, you get player name before you check if he is connected, its BIG mistake, also you dont need to check if params is strlen, but you need to check if its strlen(tmp), compare whole cmd to yours, to see how you need to make something in future
