PHP: preg_match_all parse error

My code gives a parse error and I cannot find the problem.
<pre><?php

$html = '
<div>
 <div>
  <p>
   <strong>Hello
  </p>
 </div>
';

echo htmlentities(checkTags('div',$html));

function checkTags( $tag, $xml ) {
  $tag = preg_quote($tag);
  preg_match_all('{<'.$tag.'[^>]*>(.*?)</'.$tag.'>.'}', $xml, $matches, PREG_PATTERN_ORDER);
  return $matches[1];
}

?></pre>

Thanks, I don't know where to add or remove the single quote.

I found that code on this page:
http://www.catswhocode.com/blog/15-php-regular-expressions-for-web-developers
<pre><?php

$html = '
<div>
 <div>
  <p>
   <strong>Hello
  </p>
 </div>
';

$zzz=checkTags('div',$html);
print_r($zzz);

function checkTags( $tag, $xml ) {
  $tag = preg_quote($tag);
  preg_match_all('{<'.$tag.'[^>]*>(.*?)</'.$tag.'>}', $xml, $matches, PREG_PATTERN_ORDER);
  return $matches[1];
}

?></pre>

Can you tell us in plain language what you want that regular expression to do for you?  There might be a better way!
