If you don't care about the exact way to fix the mismatched tags, you
can just feed the fragment to an instance of DOMDocument and let it
repair the HTML for you:
<?php
$fragment = '<div style="font-weight: bold">Lorem ipsum <div>dolor sit amet,
<strong><em>luptate</strong></em>. Excepteur proident,
<div class="foo">sunt in culpa</div> officia est laborum.';
$dom = new DOMDocument;
libxml_use_internal_errors(TRUE);
$dom->loadHTML($fragment);
libxml_use_internal_errors(FALSE);
echo $dom->saveHTML();
?>
This prints:
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"
"http://www.w3.org/TR/REC-html40/loose.dtd">
<html><body><div style="font-weight: bold">Lorem ipsum <div>dolor sit amet,
<strong><em>luptate</em></strong>. Excepteur proident,
<div class="foo">sunt in culpa</div> officia est
laborum.</div></div></body></html>
(There's probably a way to print only the node but I still haven't
figured it out.)
