Code

function _invisimail_encode_string($string, $js, $link = FALSE) {
  $encode = '';
  for ($i = 0; $i < strlen($string); $i++) {
    $char = substr($string, $i, 1);
    $encode .= '&#' . ord($char) . ';';
    if ($js && $link) {
      if (in_array($char, array(
        '.',
        '@',
      ))) {

        // break strings after ats and dots.
        $encode .= "'+'";
      }
    }
  }
  return $encode;
}
