<?php$html = <<< HTML<html><head><?php echo '<title>title</title>'; ?></head><body><?phpecho 'hello world!';?></body></html>HTML;$tidy = tidy_parse_string($html);$num = 0;get_php($tidy->html());function get_php($node) { // check if the current node is PHP code 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 $child) { get_php($child); } }}?>
