Took me forever to find this, so I thought I'd share - if you want to search a string for
occorences of another, excepting cases where the search string appears within an HTML tag, and you
surround the results with HTML, here's what you need:
$strIn = preg_replace("/(^| |\n|\r|\t|\]|>|\")(".$searchterm.")(([\.,]+[
$\n\r\t])|$|\"|<|\[| |\n|\r|\t)/si", '\\1<span
class="cssHighlight">\\2</span>\\3', $strIn);
This is in the code of the vBulletin software, available at vBulletin.com. It's used in the
search engine to highlight searched-for terms in results.
