    for k, v in pairs(tbl) do
        -- Check the key type (ignore any numerical keys - assume its an array)
        if type(k) == "string" then
            result = result.."[\""..k.."\"]".."="
        end

        -- Check the value type
        if type(v) == "table" then
            result = result..table_to_string(v)
        elseif type(v) == "boolean" then
            result = result..tostring(v)
        else
            result = result.."\""..v.."\""
        end
        result = result..","
    end

And how to do string to table? Do you have an example of that?

You could use a split function like:

function split(inputstr, sep)
        if sep == nil then
                sep = "%s"
        end
        local t={}
        for str in string.gmatch(inputstr, "([^"..sep.."]+)") do
                table.insert(t, str)
        end
        return t
end
