HTML Purifier Coding Help?

I read the http://htmlpurifier.org/docs/enduser-youtube.html doc, but I still can't figure out where to put the code to allow object, param and embed tags and Use experimental features wi开发者_开发百科th my htmlpurifier. Can someone please show me how to do this?

Add this.

 $config->set('HTML.SafeObject', true);
 $config->set('HTML.SafeEmbed', true);

To this.

 require_once '../../htmlpurifier/library/HTMLPurifier.auto.php';

 $config = HTMLPurifier_Config::createDefault();
 $config->set('Core.Encoding', 'UTF-8'); // replace with your encoding
 $config->set('HTML.Doctype', 'XHTML 1.0 Strict'); // replace with your doctype
 $config->set('HTML.SafeObject', true);
 $config->set('HTML.SafeEmbed', true);
 $purifier = new HTMLPurifier($config);

 $about_me = mysqli_real_escape_string($mysqli, $purifier->purify($_POST['about_me']));

The HTML.SafeObject eats a lot of memory I do not recommend you:
