Why not just limit it to one <br>?
<?php
$string="blah<br><br><br><br><br><br><br><br><br>stuff";
while ( stristr($string, '<br><br>') ) {
$string=str_replace('<br><br>', '<br>', $string);
}
echo $string;
?>
something like that would wok well enough...

Subject: [PHP] Regex Form Filter Help
I have a site where users can type whatever they want in and it posts it
to a
database. I'm trying to eliminate whatever types of abuse I can think
of,
and, since I'm using nl2br on the posts, I'm afraid a user might just
hold
down enter for a couple of seconds and scroll everything off the page.
I'm
trying to figure out a regex pattern that searches for say, more than 5
<br
/> strings in a row, and anything after 5 gets stripped out. Any ideas
on
how to possibly do this?
