Steve Waag from Lacanche Ranges was able to translate the ASP in Masking Your Email Address to PHP.

<?php
function maskEmail($email) {
  $maskedEmail = '';
  for ($j = 0; $j < strlen($email); $j++) {
    $maskedEmail .= '&#' . ord(substr($email, $j, 1)) . ';' ;
  }
  $emailHtml = '<a href="m&#' . ord('a') . ';&#' . ord('i') . ';&#' . ord('l')
    . ';&#' . ord('t') . ';o:' . $maskedEmail . '">' . $maskedEmail . '</a>';
  return $emailHtml;
}
?>

<p>For more information email me at
  <?php echo maskEmail('someEmail@someDomain.net') ?>.</p>
