This is on the Firefox Forums, and may be a bug, or some kind of clash with plugins:

The user wrote the following:
<?php echo 'Nice Test'
<?
which resulted in a long blank page.
Anyone seen this in another forum or know what might cause it?

well I am no expert on the subject matter but at least the tag to close the php-thingy is wrong way around (the second one)...so it never gets closed...what effect that has on the page is anyone's guess...
I would guess preventing people from using html on message would also prevent people from using php-stuff like that....but I let the geeks here answer you more in detail
I guess it is because html is on, i have disabled HTML and it is working fine.
did you duplicate the thing with the typo where <? opens but there's no ?> to close ...only another <?
Yes I duplicated it exactly as he said, and which was performed on that forum with the bug.
Well it seems to be an isolated case on the Firefox forums then...
Okey, it does the same on my forum.
well it doesn't repeat itself. this is in the source of the page however.
<p><?php echo 'Nice Test'<br />
<?</p>
Still that would render as an unclosed/unknown html tag and won't do any damage.
