Answer 1

This is works for me to close any open HTML tags in a script.

#iU', $html, $result);
$openedtags = $result[1];
preg_match_all('##iU', $html, $result);
$closedtags = $result[1];
$len_opened = count($openedtags);
if (count($closedtags) == $len_opened) {
    return $html;
}
$openedtags = array_reverse($openedtags);
for ($i=0; $i < $len_opened; $i++) {
    if (!in_array($openedtags[$i], $closedtags)) {
        $html .= '';
    } else {
        unset($closedtags[array_search($openedtags[$i], $closedtags)]);
    }
}
return $html;
}
