This module implements the spamspan technique (http://www.spamspan.com ) for hiding email addresses from spambots. If javascript is disabled on the client-side, addresses appear as example [at] example [dot] com.

Code

function spamspan_callback($matches) {

  // Replace .'s in the address with [dot]
  $user_name = str_replace(".", " [dot] ", $matches[1]);
  $domain = str_replace(".", " [dot] ", $matches[2]);
  return '<span class="spamspan"><span class="' . variable_get('spamspan_userclass', 'u') . "\">{$user_name}</span>" . variable_get('spamspan_at', ' [at] ') . "<span class=\"" . variable_get('spamspan_domainclass', 'd') . "\">{$domain}</span></span>";
}
