php setup: ./configure  --with-apxs=/usr/local/etc/httpd/bin/apxs --enable-versioning --with-mysql --enable-track-vars

script: <?php
	print strip_tags("> from an earlier email\n");
?>

prints

X-Powered-By: PHP/4.0.4
Content-type: text/html

 from an earlier email

and not
> from an earlier email

I'm writting an application which prints email messages and noticed this behavior in messages that quoted the previous message with the string "> ".  I expected strip_tags to do the equivalent of ereg_replace("<[^>]*>", "", $msg)
