HazardouS already told you the problem

if you want to use the function a bit more dynamic you should remove some parts
so it only modifies the string and doesn't send anything

pawn Код:

CheckQuickStrings(playerid, string[], size = sizeof string)
{
    new idx = strfind(string, "$");

    if(idx != -1)
    {
        do
        {
            if(strcmp(string[idx], "$loc", true, 4) == 0)
            {
                new zone[MAX_ZONE_NAME];
                GetPlayer2DZone(playerid, zone, MAX_ZONE_NAME);

                strdel(string, idx, idx + 4);
                strins(string, zone, idx, size);
                continue;
            }
            if(strcmp(string[idx], "$cash", true, 5) == 0)
            {
                new pmoney[32];
                format(pmoney, sizeof(pmoney), "$%d",GetPlayerCash(playerid));

                strdel(string, idx, idx + 5);
                strins(string, pmoney, idx, size);
                continue;
            }
            if(strcmp(string[idx], "$ply", true, 4) == 0)
            {
                new id = GetPlayerWhoIsClosest(playerid);
                if(!IsPlayerConnected(id)) id = playerid;

                new closeststr[32];
                format(closeststr, sizeof(closeststr), "%s (%d)", PlayerInfo[id][pName], id);

                strdel(string, idx, idx + 4);

                continue;
            }

}

You probably need to edit OnPlayerText also
