Supply the tags you want to keep when you call strip_tags.

$stripped = strip_tags($data, '<br/><br>');

I can do that, but my question had to do with strip_tags seeming to get
rid of \n's, not <br> tags. This is why I was concerned. If I run
strip_tags(), followed by nl2br, the <br> tags that nl2br generates
should be there.

Are you sure there are newlines before you run strip_tags? It doesn't
touch newlines because they aren't html entities.

$ cat eg.php
<?php

$string = "<b>here is a bold tag</b>\n<a
href='http://www.example.com/'>Link to example.com</a>\n\n";

echo "Strip tags only:\n";
echo strip_tags($string) . "\n";
echo str_repeat('-', 10) . "\n";
echo "Strip tags & nl2br:\n";
echo nl2br(strip_tags($string)) . "\n";
?>

$ php eg.php
Strip tags only:
here is a bold tag
Link to example.com


----------
Strip tags & nl2br:
here is a bold tag<br />
Link to example.com<br />
