Email obfuscator

A kick-ass email obfuscator, based on my obfuscate_email() PHP function. This tool will encode (HTML) and/or reverse (CSS) any email address you enter, making it less vulnerable to spammers who use e-mail harvesting software aka spambots.

The input

Code

function obfuscate_email($email, $encode = 1, $reverse = 0, $before = '<span class="email">', $after = '</span>') {
 $output = '';
 if ($reverse) {
  $email = strrev($email);
  $output = $before;
 }
 if ($encode) {
  for ($i = 0; $i < (strlen($email)); $i++) {
   $output .= '&#' . ord($email[$i]) . ';';
  }
 } else {
  $output .= $email;
 }
 if ($reverse) {
  $output .= $after;
 }
 return $output;
}
