To use the class, simply include it on your PHP file:
  include('class.entitize.php');
Then, instantiate the class:
  $entitize = new Entitize();
Now, you can convert any string into HTML entities by doing so:
  $email = $entitize->convert('
[email protected]');
  $text = 'This text is not readable when viewed in source code';
  $text = $entitize->convert($text);
Have fun!
