PHP INCLUDE Cryptograph

<?php

    $salt ='whatever_you_want';

    function simple_encrypt($text)
    {
        return trim(base64_encode(mcrypt_encrypt
(MCRYPT_RIJNDAEL_256, $salt, $text, MCRYPT_MODE_ECB, 
mcrypt_create_iv(mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256, MCRYPT_MODE_ECB), 
MCRYPT_RAND))));
    }

    function simple_decrypt($text)
    {
        return trim(mcrypt_decrypt(MCRYPT_RIJNDAEL_256, $salt, 
base64_decode($text), MCRYPT_MODE_ECB, 
mcrypt_create_iv(mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256, MCRYPT_MODE_ECB), 
MCRYPT_RAND)));
    }

?>

I'm using XAMPP 1.7.4 with PHP 5.3.5 as well, no problem here. It's 
configured "--with-mcrypt=static", Version 2.5.8 is enabled by default. 
No need to enable the extension (which I had to do for Fileinfo, though;
 just uncomment extension=php_fileinfo.dll in xampp/php/php.ini) 

Nice to try....
