Can't get PHP to work

Question

I've gone through the articles at
http://www.adobe.com/devnet/dreamweaver/articles/php_macintosh.html
and
http://www.macdevcenter.com/pub/a/mac/2005/08/16/apache.html?page=2
regarding enabling PHP on Tiger, but can't get started.
The problem seems to be with httpd.conf
I configured it the way I'm supposed to, I think and if I run the Terminal command sudo apachectl configtest it tells me the server is configured ok.
If I run php -version, it tells me I have PHP 4.4.1 installed.
But when I try to test the server by going to
http://localhost/~yourusername/timetest.php Safari tells me it can't connect.
If I restore the httpd.conf file from default, and make sure personal web sharing is turned on, the basic html service works, but of course PHP doesn't.
Any ideas?

I just copied and pasted the commands you sent me into Terminal and it seemed to work, but I have almost no experience with Terminal.
Then I uncommented the lines in the httpd.conf file to turn PHP on and restarted personal web sharing. Unfortunately when I dial http://localhost/~unsername/ I am again getting the message that Safari can't connect to the server.
When I use the tail /var/log/httpd/error_log command I get told a file called 'favicon.ico' doesn't exist.
I fooled around with the server a few times in the past and threw out the Apache start page. I might have trashed something else, I guess.
Here is output from the Terminal window (There are three users on this Mac: moi, client and stu).
