Hello,
I'm having trouble with the script below:
Code:
<form action="safe.php?process=y" method="POST">
Text: <input type="text" name="text" size=40>
<input type="submit" value="Submit"><input type="reset" value="Clear"><BR>
Scrable Text:<input type="radio" name=type value=encript> Descrable Text<input type="radio" name=type value=decript>
</form>
<BR>
<BR>
<BR>
<?php
$get = $_GET['process'];
if ($get == 'y'){

$text = $_POST['text'];

function scramble($t)
{
if ($_POST['type'] == 'encript') {
 str_replace("a", "s", $t);
 str_replace("A", "S", $t);

Can you find anything wrong with this script?

Hey,

I would put the scrablem($text) function call outside the function.

In order to replace the string as you are trying to do you need to put the new string in a variable. For instance.

$newT=str_replace("a", "s", $t);

echo("<BR>" . $newT);


Try that.

<input type="submit" value="Submit"><input type="reset" value="Clear"><BR>
Scrable Text:<input type="radio" name=type value=encript> Descrable Text<input type="radio" name=type value=decript>
</form>
<BR>
<BR>
<BR>
<?php
$get = $_GET['process'];
if ($get == 'y'){

$text = $_POST['text'];

function scramble($t)
{
if ($_POST['type'] == 'encript') {
$t = $t;
$new = str_replace("a", "s", $t);
$new .= str_replace("A", "S", $t);
