Hi,

I have the following machine:

- Windows ME
- Xitami server(just installed)
- PHP 4.05 (just installed)

When running this script:

class rc4crypt {

	function endecrypt ($pwd, $data, $case) {

		if ($case == 'de') {

			$data = urldecode($data);

		}

		$key[] = "";
		$box[] = "";
		$temp_swap = "";

		$pwd_length = strlen($pwd);

			$box[$i] = $i;

			$box[$x] = $temp_swap;

		}

		$temp = "";
		$k = "";

		$cipherby = "";
		$cipher = "";

		$a = 0;
		$j = 0;

		for ($i = 0; $i < strlen($data); $i++) {

			$a = ($a + 1) % 256;
			$j = ($j + $box[$a]) % 256;

			$temp = $box[$a];
			$box[$a] = $box[$j];

			$box[$j] = $temp;

			$k = $box[(($box[$a] + $box[$j]) % 256)];
			$cipherby = ord(substr($data, $i, 1)) ^ $k;

			$cipher .= chr($cipherby);

		}

		if ($case == 'de') {

			$cipher = urldecode(urlencode($cipher));

		} else {

			$cipher = urlencode($cipher);

		}

		return $cipher;

	}


}


$rc4 = new rc4crypt; 

echo "<BR><BR>";
$msg="mmmmmmmmmmmmmmmmmmmmmmm3mmmmmmmmmmmm";
$d = $rc4->endecrypt("hi div", $msg, "");
echo $d;

?>

--------------------------
I get the following error:
--------------------------

"Php has caused an error in PHP4TSDLL.
Php will now close.

If you continue to experience problems,
try restarting your computer."

--------------------------
...and I did restart... but the message wont go away! I uploaded the script to a unix server running apache with PHP v. 4.01pl and it works fine...

Also, if we change the variable $msg to, for example, "abc" it works...

Any ideas?!
