getting started problems

there's something wrong with my php setup that i can't pin down. i'd be most grateful for any advice. i am running: FreeBSD 4.4-RELEASE #1. from the ports collection i have installed apache, mod_ssl and, more recently, mod_php4. on start, my apache logs says: Apache/1.3.20 (Unix) PHP/4.0.6 mod_ssl/2.8.4 OpenSSL/0.9.6a configured i managed to make a couple of php things from the basic tutorial work including: <p>Today is <?php print strftime("%m/%d/%Y"); ?></p> <?php phpinfo(); ?> if you go to http://fsbsd.thefsb.org/test/test.php you can see the results which show my php configuration. but most other things from the tutorials and elsewhere don't work. for example, the line: <?php echo "Hello World<p>"; ?> produces a parse error. sometimes it's a different error but the parse error is by far the most common. ideas? thanks c u fsb
