php not displaying correctly

[Kidrandom]

I have just started learning PHP from a training Cd and I'm having trouble with a script not displaying properly. I'm Running mac os x 10.5.5

Personal web sharing activated apache running, I have edited httpd.conf and removed the # from
LoadModule php5_module libexec/apache2/libphp5.so

made a simple page in php

<?php echo "hello world "; ?>

saved the page /user/Sites/index.php
and it just displays a blank page in the browser. Also when I view the page source code the php lines are visible and highlighted pink.

A PHPtest page with the PHP code:

<?php phpinfo(); ?>

works, and displays the Entropy version correctly.

Can anyone point me in the correct direction

Thanks.

Are you launching the page as a "http://localhost/index.php" link from your browser address bar, or opening it directly from the file system? (You normally have to open it as a localhost link in order to have the web server process the request.)

yep, spot on. Thanks for your help.
