Great!
Thank-you.
But I can only use this temporarily, because it's not exactly what I need. I want to specify tags for inclusion. Not for exclusion.
So currently I can go:
strip_tags($text, '<p><div>');
However, that's specifying tags to exclude. Whereas I want something like this:
strip_tags_only($text, '<font>');
To specify the only tags included in the stripping.
