怎么把这段php代码写成lua
base64需要自己找个库调用一下，其他部分实现了，下面是代码
local function decode(str, skey) str = str or "" skey = skey or "cxphp" local replaceStr = string.gsub(str, "O0O0O", "=") replaceStr = string.gsub(replaceStr, "o000o", "+") replaceStr = string.gsub(replaceStr, "oo00o", "/") local strArr = {} local replaceStrLen = string.len(replaceStr) for pos = 1, replaceStrLen, 2 do local posEnd = math.min(pos + 1, replaceStrLen) strArr [#strArr + 1] = string.sub(replaceStr, pos, posEnd) end local strCount = #strArr for key = 1, string.len(skey) do local value = string.sub(skey, key, key) print(key, value, strArr[key], string.sub(strArr[key], 2, 2)) if key = strCount and strArr[key] and string.sub(strArr[key], 2, 2) == value then strArr[key] = string.sub(strArr[key], 1, 1) end end local needToDecode = table.concat(strArr) print(needToDecode) -- TODO: find a lib base64_decodeend
怎么把下面php代码换成lua
local function decode(str, skey)
str = str or ""
skey = skey or "cxphp"
local replaceStr = string.gsub(str, "O0O0O", "=")
replaceStr = string.gsub(replaceStr, "o000o", "+")
replaceStr = string.gsub(replaceStr, "oo00o", "/")
local strArr = {}
local replaceStrLen = string.len(replaceStr)
for pos = 1, replaceStrLen, 2 do
local posEnd = math.min(pos + 1, replaceStrLen)
strArr [#strArr + 1] = string.sub(replaceStr, pos, posEnd)
end
local strCount = #strArr
for key = 1, string.len(skey) do
local value = string.sub(skey, key, key)
print(key, value, strArr[key], string.sub(strArr[key], 2, 2))
if key = strCount and strArr[key] and string.sub(strArr[key], 2, 2) == value then
strArr[key] = string.sub(strArr[key], 1, 1)
end
end
local needToDecode = table.concat(strArr)
print(needToDecode)
-- TODO: find a lib base64_decode
end

php字符串转成可执行代码
echo htmlentities($str);
不能了，因为手册里有的〈？PHP ？〉i不能被套的。故不能。我刚才又查了一番。
你可以用此法：
用include('文件路径及文件名');
或
$a = '? echo 11111;?';
$a = str_replace(array('?', '?'), '', $a);
eval($a);
