I have always wanted to know how to do this, if it is possible please tell me with an explanation on how it works

[albrat]

I had troubles understanding it at first then once I got the hang of string.* () (from the lua handbook) I couldn't understand why I had so much trouble with it.

text = "this string is for splitting" -- our text
for a = 1, string.len(text)+1 do  -- for 1 to the number of letters in our text + 1
print (string.sub(text, a,a)) -- split the string with the start and end at "a"
end  -- repeat untill the for loop ends

The above code will simply print each character to the screen.
instead of print(...) you could use a table and insert each character into a table, eg. tabletxt = string.sub(text,a,a)


edit :: oopsy, I did not miss a , while typing too fast. ( looks around and checks if anyone is looking and corrects the typo. ) ** stealths away into the sunshine **

Overkill time!... (That means: Yes, I know the question's been answered already, but I feel like posting an answer anyways.)
You could use Lua patterns for this as well:

local str = "something"
local result = {}
for letter in str:gmatch(".") do table.insert(result, letter) end

By the way:

You miss a comma on the third line after "text".
EDIT: AND string.len(text) + 1 is totally nothing, since it's the n+1st character of an n-long string. Use "#text"

I origionally typed it as #text but second guessed myself and changed it. lol (moments insanity) (extended version)

even easier

local function split(str)
  if #str>0 then return str:sub(1,1),split(str:sub(2)) end
end

you don't have to define a table but you can just

local results={split("randomstring!!")}

if you want a table and

local res1,res2,res3=split("hai")

if you want individual vars
