As you've already noticed yourself, the strip_tags() function makes
sense when applied to HTML. As such, I think it's good enough, though
you won't get predictable results if the HTML is not valid (which is
normally the same that happens with web browsers).
Sadly, it's pretty often used on plain text, leading to annoyances and
data loss. Have you ever posted a comment on a programming web site,
just to find out that your code snippets were ruined by the forum? There
you are.
