PHP tidy disable repair feature, just indent

Question

My code looks like that

$markup = ob_get_clean();

// Specify configuration
$config = array(
    'indent' => true,
    'output-xhtml' => true,
    'wrap' => 200);

// Tidy
$tidy = new tidy;
$tidy->parseString($markup, $config, 'utf8');
$tidy->cleanRepair();

There is a big problem: My web php code gets string from database that contains programming materials (like include , etc) and tidy gets <stdio> as wrong tag, "repairs" (removes it from output) Is there any way to just indent code? I mean not to repair and remove parts of material like <stdio>??

Answer 1

I think htmspecialchars() and htmlspecialchars_decode() functions may help you.
