beginner:php scripts,header attached to output Why?

Hi I am a beginner to Jigsaw server and php.
I got php and Jigsaw configured to work together to create a new
extension. 
Using instructions I found at http://www.circle.ch
However the php script although it works well and produces output, the
server always attaches the header to the output.
Hence I have my php file as 

<HTML>
<HEAD>
<TITLE> Hello Date program</TITLE>
</HEAD>
<BODY>
TODAYS DATE: <? print(Date("1 F d, Y")); ?>
</BODY>
</HTML> 
 
AND when I say 
http://localhost:8001/hello.php3
I get the following output

Content-type: text/html TODAYS DATE: 1 May 04, 2000

Why is the content/typw header automatically attached to my output. How
can I prevent this
ANy help will be greatly appreciated
