Here you go:

PHP код:

stock TDConvertPrice(price)
{
    new pricestring[50], j = valstr(pricestring, price);
    while(j > 0)
    {
        if(j % 3 == 0 && pricestring[j] != '\0')
            strins(pricestring, "~y~,~w~", (strlen(pricestring) - j));
        j--;
    }
    strins(pricestring, "~g~$~w~", 0);
    return pricestring;
} 


I'd suggest using custom specifiers for this kind of formatting,
