*
* Provides basic encoding of any string
*
* @param string $string any string
* @param string $key password for encoding
* @return string $result gives back i.e. dsf32dfh7ghj6cv2
*/
function encrypt($string, $key) {
$result = '';
for($i=0; $i<strlen($string); $i++) {
$char = substr($string, $i, 1);
$keychar = substr($key, ($i % strlen($key))-1, 1);
$char = chr(ord($char)+ord($keychar));
$result.=$char;
}
return base64_encode($result);
}
...etc.
