Personally, I've been ignoring this thread.  The error message PHP 
produces is completely clear about what and where the problem is.  But 
Dan, who's pretty good about stuff, posted, and I was curious about what 
drew him into the fray.  I've got to disagree with a few things he said.

Actually, the error message says "output started at... 
registrationverified.php:3."  The ":3" means line 3.  That aside,

Nope.  PHP is okay with one line break after the ?>, but not two.

I agree it's much cleaner to not include the closing ?> at the end of the 
file.  But putting a comment about it being the end of the file is 
completely supurfluous.  The end of the file is the end of the file.
