      if (    is_uploaded_file($HTTP_POST_FILES['userfile']['tmp_name']))
      {
             copy($HTTP_POST_FILES['userfile']['tmp_name'], "/$realname");
         echo     "Upload Filename: " . $HTTP_POST_FILES['userfile']['name'];
             $xx=encodeNow("/$realname");
      }
      else {
         echo     "Upload not complete";
       }
    ?>

    <html>

    Coders section is not a general 'I need something fixed so lets ask you guys to fix it for me' forum! If you have a specific problem, for instance a typecast that's giving you trouble or a regex that's not working correctly, feel free to ask. But do not dump here 50 lines of code with the message 'its not working, fix please', or expect us to write your scripts for you!
    And what is the actual issue? I see a decodeNow and encodeNow function. What is the problem?

    Most of us, myself included, aren't going to help you whatsoever without more information. Tell us what problems/errors you are having. What line are the errors on? Where do you think the problem may be originating from? What doesn't work like you want it to?

    Make sure you paste relevant code, indicate what you tried already, etc. If we have to guess what help you want it'll take a lot longer before we can help you!

    As stated
    I have this code, it decodes an encoded message.
    But what if want to encode the decoded message?
    This code works for decoding a message, but it doesn't work for encoding.
    I'm just asking if someone can check the code what I did wrong.

    There is no error.

    Doesn't do anything... leaves page blank,

    PHP Code:
    function encodeNow($file) { 
        global     $encode; 
            $text = file_get_contents($file, true); 
            $max = strlen($text); 
        for (    $i=0; $i<$max; $i++) { 
               $ii=hex2bin($text[$i]); 
           if (empty(    $encode["$ii"]) && $encode["$ii"]!=0) { $out.="x"; } else $out.=$encode["$ii"]; 
               //echo "$i = $ii<br>"; 
            } 
        return     $out; 
    }
