Try this:

function simple_encrypt($text)
{
    global $salt;
    return base64_encode(mcrypt_encrypt(MCRYPT_RIJNDAEL_256, $salt, $text, MCRYPT_MODE_ECB));
}

function simple_decrypt($text)
{
    global $salt;
    return base64_decode(mcrypt_decrypt(MCRYPT_RIJNDAEL_256, $salt, $text, MCRYPT_MODE_ECB));
}
