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 />
