Help to reverse..

[egz]

Hi, I need some help to find out what the "iamahacker" sting at bottom, was at the start, before rot13 and such

[CODE]
<?PHP

$z = $_POST['pw'];
$x = str_rot13($z);
$y = preg_split(\"//\", $x, -1, PREG_SPLIT_NO_EMPTY); 
$y = implode(\".\", $y);
$a = explode(\".\", $y);
$a = array_reverse($a);
$a = implode(\"\", $a);


if(isset($_POST['submit']) && $a == \"iamahacker\")
{
header(\"location: ?page=level23&pw=$z\");
}

?>
[/CODE]

I am a noob at php :P , the "iamahacker", what would that end up as, if you sendt it throught the script in reverse order ..?

I dont know what you are talking about either. If you wanna "decode" a str_rot13() string, just use the function on the string again.

ex:
[CODE]<?php

$string = "iamahacker";
echo "<p>$string</p>"; // Original string...

$string = str_rot13($string); // ROT13 encode the string
echo "<p>$string</p>";

$string = str_rot13($string); // ROT13 "decode" the string
echo "<p>$string</p>";

?>[/CODE]
