Phpdig indexing including HTML in results
 

If you look at the site http://www.fact.co.uk/phpdig/search.php, and search, you will see HTML sometimes gets included in the page results.

The only thing I can think of is that in some of the pages I have been required to use JavaScript with escape characters so the site validates in XHTML.

The actual stripping of tags doesn't change the results, I think it is in the reading of the file, as I have echoed out the contents of the $content_file variable and it "breaks" at certain points.

The script works great aside from this and I would be very grateful for any advice.

It's your left sidebar HTML, using &lt; for < and using a hard > to end the tags.
