strip_tags() is a default HTML Tag stripper in PHP. However, it can't strip some of the tags, so this enhanced version called strip_html_tags will remove more html elements.

How to strip HTML tags, scripts, and styles from a web page:
 * Remove HTML tags, including invisible text such as style and
 * script code, and embedded objects.  Add line breaks around
 * block-level tags to prevent word joining after tag removal.
function strip_html_tags( $text )
    $text = preg_replace(
          // Remove invisible content
          // Add line breaks before and after blocks
            ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ',
            "\n\$0", "\n\$0", "\n\$0", "\n\$0", "\n\$0", "\n\$0",
            "\n\$0", "\n\$0",
        $text );
    return strip_tags( $text );

can't strip some of the tags

Which ones?  Have you got an example showing how it fails?  While it's a fairly brittle function, I think it works well if you have valid HTML.
