Corona SDK. Use like split -- pass in divider character and a string and get back a table/array holding each piece between the dividers.

StringExplode.lua

-- works like PHP explode() function
function explode(div,str) -- credit: http://richard.warburton.it
  if (div=='') then return false end
  local pos,arr = 0,{}
  -- for each divider found
  for st,sp in function() return string.find(str,div,pos,true) end do
    table.insert(arr,string.sub(str,pos,st-1)) -- Attach chars left of current divider
    pos = sp + 1 -- Jump past current divider
  end
  table.insert(arr,string.sub(str,pos)) -- Attach chars right of last divider
  return arr
end
