</body></html>
Outside HTML

$tidy = tidy_parse_string($html);
$num = 0;
 
get_nodes($tidy->html());
 
function get_nodes($node) {
 
    // check if the current node is of requested type
    if($node->isPhp()) {
        echo "\n\n# php node #" . ++$GLOBALS['num'] . "\n";
        echo $node->value;
    }
 
    // check if the current node has childrens
