Personal Webpage doesn't work

Question

I just got through with a 3+ hour fight to install PHP on my MBP (Tiger 10.4.9). Now that everything's all up and running (allegedly... PHP eventually installed properly, and I restarted Personal Web Sharing a few times, as well as my computer), nothing will show up. Going to http://10.0.1.200/ produces the default Apache whathaveyou. But when I try to access http://10.0.1.200/~username, I get a 404 error.
I've put files in both my sites folder and WebServer/Documents, to no avail. Nothing shows up and I keep getting 404s.
What's this all about?

Answer 1

Ignore the favicon.ico error message. If you put a favicon.ico file in the folder the image will appear in the URL bar and the error will stop, but it's unimportant.

Say this in Terminal:
/private/etc/httpd/users
Then this:
sudo nano bean5
The first line will say:
<Directory "/Users/bean5/Sites/">
This is the directory of your websites, you can change it to whatever you want. When you are done, press ctl-o then return to write the file, then ctl-x to quit the editor. Restart Apache to make the new settings take effect.

You would need to set the PHP default file to "index.php" or whatever you want.
Open the same file and add this line just under the one you worked on before:
DirectoryIndex index.php
Save the file and quit the editor. Restart Apache and bring up your user webpage in a browser. Notice that you do not now even see the "index.html" part. You can set custom default pages for all your webfolders and hide the actual file. Users never need to see them.
You may actually see text rather than the PHP script executing. If that happens post here.
