[轉]lua中string split函數

function Split(szFullString, szSeparator)

local nFindStartIndex = 1

local nSplitIndex = 1

local nSplitArray = {}

while true do

   local nFindLastIndex = string.find(szFullString, szSeparator, nFindStartIndex)

   if not nFindLastIndex then

    nSplitArray[nSplitIndex] = string.sub(szFullString, nFindStartIndex, string.len(szFullString))

    break

   end

   nSplitArray[nSplitIndex] = string.sub(szFullString, nFindStartIndex, nFindLastIndex - 1)

   nFindStartIndex = nFindLastIndex + string.len(szSeparator)

   nSplitIndex = nSplitIndex + 1

end

return nSplitArray

end

--測試

local str = "1234,389,abc";

local list = Split(str, ",");

for i = 1, #list

do

str = string.format("index %d: value = %s", i, list[i]);

print(str);

end
