Lua find a key from a value

Question

I\'m working with this:

    chars = {
         [\"Nigo Astran\"]=\"1\",
         [\"pantera\"]=\"2\"
         }

   nchar = (chars[$name])+1

Answer 1

the best way to do that is like this

 local autoreply={
['hey']='hi',
['how are u']='am fine what about u?',
['how r u']='am fine what about u?',
['how are you']='am fine what about u?',
['sleep']='rockabye bayby good dreems',
['السلام']='وعليكم السلام ورحمة الله وبركاته',
}
local keys={'hey','how are u','how r u','how are you','sleep','السلام'}
function getValueFromKey(table,key)
  for k,v in ipairs(keys)do
  if string.find(string.upper(key),string.upper(v)) then return table[v] end
  end
   return false
end
