I have written function that :
1) turns the small Symbols into upper case symbols. And Also:
2) turns the upper case symbols into smoller case symbols.

function N($str)

{

   for($i=0; $i<=strlen($str); $i++)

   {

   

       if(ord($str[$i])>=97 && ord($str[$i]<=122)){

	   $str[$i]=chr(ord($str[$i])-32);

	   }

	   else if(ord($str[$i])>=65 && ord($str[$i]<=90)){

	   $str[$i]=chr(ord($str[$i])+32);

	   }

	   

   }

   echo $str;

}


$str="ABC abc";

N($str); 

everything works well, but if i write "else" instead of "else if", it does not works. I don't understand why?

Well, space is not in either of those ranges.
