Hey, I haven't coded for about 2 years.

Doing a small project that involves making a translator sort of script which will translate text.

E.g I type in "hello" click a button, and the text that comes out is "fummi" you know like replaces the alphabet with different letters e.g h=f e=u l=m o=i

I've been looking on net for ages and have no idea what to use and so far have got nowhere, hopefully some of you can help!

Can anyone find me or write me some examples?

Thanks in advance, Ash!

Hello Ash,

I will need to get more clarification before I can help you.

Do you want a translator as in translating languages example: "Hello" - English to "Bonjour" - French? Similar to babel fish?

OR

Do you want a cryptogram? Example: A = Z, B = Y, C = X etc...

So if you typed in "Hello" you would get "Svool"?

You might want to take a look at http://us3.php.net/strtr . It pretty much does all the work for you except setup the key you want to use for transformation.

Yes what I mean is say translating "hello" into "gavvi" some sort if page in which you can type in something and what you typed will be changed, almost like a code language.

Thanks For Your Help So Far

So like:

HTML Code:

<html>
<head>
  <title>Bored Cryptography</title>
</head>
<body>
  <form action="encrypt.php" method="post">
    Input:<input type="text" name="input" value="<?php echo $_GET['output']; ?>" /><br/>
    <input type="submit" value="Encrypt"/>
  </form>
</body>
</html>

And in the 'encrypt.php' file:

PHP Code:


			
<?php
  $input = $_POST['input'];

  $replacementChars = array(
    "a" => "o",
    "b" => "p",
    "c" => "q",
    "d" => "r",
    "e" => "s",
    "f" => "t",
    "g" => "u",
    "h" => "v",
    "i" => "w",
    "j" => "x",
    "k" => "y",
    "l" => "z",
    "m" => "a",
    "n" => "b",
    "o" => "c",
    "p" => "d",
    "q" => "e",
    "r" => "f",
    "s" => "g",
    "t" => "h",
    "u" => "i",
    "v" => "j",
    "w" => "k",
    "x" => "l",
    "y" => "m",
    "z" => "n");

  $output = strtr($input, $replacementChars);

  echo('<script type="text/javascript">
  window.location="input.php?output=$output"
  </script>');
?>

P.S - Sorry if you wanted to do it yourself. Obviously, it's not that hard if I can write it up in 10min inside a quick-reply box :P

Hey thanks for reply.

The HTML I put in a file called "input.php" and I put the second lot of code in "encrypt.php" but after entering the text I wish to encrypt and clicking "encrypt" I get "$output" in the text box.

I know its most probabley one of my mistakes

Any help is appreciated.

**chrishirst** · 01-03-2009, 01:58 PM

it should be

window.location="input.php?output=" . $output

**Ashkwil** · 01-03-2009, 07:49 PM

PHP Code:


			
<?php

  $input = $_POST['input'];



  $replacementChars = array(

    "a" => "o",

    "b" => "p",

    "c" => "q",

    "d" => "r",

    "e" => "s",

    "f" => "t",

    "g" => "u",

    "h" => "v",

    "i" => "w",

    "j" => "x",

    "k" => "y",

    "l" => "z",

    "m" => "a",

    "n" => "b",

    "o" => "c",

    "p" => "d",

    "q" => "e",

    "r" => "f",

    "s" => "g",

    "t" => "h",

    "u" => "i",

    "v" => "j",

    "w" => "k",

    "x" => "l",

    "y" => "m",

    "z" => "n");



  $output = strtr($input, $replacementChars);



  echo('<script type="text/javascript">

  window.location="input.php?output=" . $output"

  </script>');

?>

This is the current code. Now the page simply stays on encrypt.php and I am left with a blank white screen.

Thanks for your help so far.

I believe it should be like this.

PHP Code:


			
echo('<script type="text/javascript"> 
  window.location="input.php?output=' . $output
  . '"</script>');

Although, why use javascript to redirect? You could simply do this.

PHP Code:


			
header("Location: input.php?output=$output");

Thanks A Lot Everyone, It Works Perfect =)

'cos you can't add header changes unless you're buffering the page, no?
And I'm using AJAX for all my sites, so Javascript was the best idea.

You shouldn't have to stick it out of the string for it to work, PHP should still parse the variable within the string, no?
