The only problem with strtr() is that I/we weren't wanting this to
translate for every tag out there...

For instance:

strip_tags($str, "<A><B><I><U>");

I was looking for something that would translate the characters if it
DID NOT match those above tags.  If it does, they would be left alone.

Possibly a good compromise would be a callback function to determine
what happens to tags that don't match the tags listed.

Use strtr() it will be much faster then modifying strip_tags with the
suggested functionality.

strtr($your_string, array(">" => "&gt;", "<" => "&lt;"));

Exactly :)

Your example is inconsistent with your explanation.  Does the following
look like the behavior you had in mind?

strip_tags("<b>hi</b><i>there</i>", "<b>", "&lt;", "&gt;");

would have an output of:

<b>hi</b>&lt;i&gt;there&lt;/i&gt;

#15972, which is open right now, had some good thoughts on how to
expand strip_tags...

My suggestion:

1. Add a third/fourth parameter to it that (if specified) says what to
change the brackets *to* instead of replacing them.

e.g.:

strip_tags("<b>hi</b><i>there</i>", "<b>", "&lt", "&gt");

would have an output of:

<b>hi</b> &lt;there&gt;

The point of this is so that rather than strip away tags that are
invalid, a forum would be able to see code just fine..  Well, that, and
we'd be able to have brackets on the site without typing in the html
equivalent ;)
