$tidy = tidy_parse_string($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
if($node->hasChildren()) {
foreach(
$node->child as $child) {
get_nodes($child);
}
}
}
