PHP is a server-side scripting language. When a browser requests a PHP page from a PHP-enabled server, the server interprets the PHP code and sends the resulting HTML to the requesting browser.
(The browser receives only HTML, not PHP code.)

PHP: Hypertext Preprocessor is the current definition.
The original definition was Personal Home Pages.

JavaScript & PHP:
JavaScript runs on the client's computer (in their browser).
PHP runs server-side and therefore has no access to JavaScript variables.

You can test your PHP installation by putting <? phpinfo() ?> in a file called phpinfo.php and store it in the htdocs dir mentioned above. Afterwards, you get into your browser and enter the following in the URL (or address) box on your Browser: http://localhost/phpinfo. (Caution: If localhost doesn't work, it could be because that name, localhost, wasn't used in the httpd.conf file as the ServerName. On your own PC it could possibly be your machine's host name.) Refer: PHP4 Installation Overview

1. PHP is a server-side, cross-platform, HTML embedded scripting language. PHP Intro
2. Create an htpasswd file.
   htpasswd -c /usr/local/httpd/uhtpasswd ctaylor (-c is only needed for first entry)
3. Create/Make a Web page in your home area. Now in order to do this .. well in order to make it readable by your Browser .. you must do the following in apache. Now, which and where, httpd.conf file to use will depend on your version of Linux. SuSE does it inside a file of their own. And the use of this file is determined by values in other files. So you get a lot of chasing around. But the important info is basically the same in all. Just have to see how your version wants to set it up. This is the important info in apache:

   <IfModule mod_userdir.c>
       UserDir public_html
   </IfModule>
   
   <Directory /home/*/public_html>
       AllowOverride FileInfo AuthConfig Limit
       Options MultiViews Indexes SymLinksIfOwnerMatch IncludesNoExec
       <Limit GET POST OPTIONS PROPFIND>
           Order allow,deny
           Allow from all
       </Limit>
       <LimitExcept GET POST OPTIONS PROPFIND>
           Order deny,allow
           Deny from all
       </LimitExcept>
   </Directory>
   

   The above values will allow you to execute your page from your home public_html area.
   Now:
   1. Make your Home Dir publicly executable (and maybe readable??).
   2. Create a public_html dir and make it publicly readable and executable.
   3. Create an index.html file within the public_html dir. This will be your home page.
   4. Make each file you create publicly readable. (executable if necessary.)
   5. Accessed via Browser by http://hostname/~username (ie: http://dusty-tr/~ctaylor)
   
   
4. In order to execute PHP from within HTML I had to add the following to httpd.conf:
   AddType application/x-httpd-php .htm
   AddType application/x-httpd-php .html

Netscape for Linux is most infamous for its crazy font scaling. They are very small to 
start with. Then you goto :
Edit > Preferences > Appearance > Fonts, and set it to say size 18, and yet, the results are 
pathetic. The ugly scaled fonts do have a solution. Get the Mozilla fonts package at 
http://fox.mit.edu/skunk/xwin/#mozilla_fonts. Unpack the archive and read the 
included README file(s).

Create a new directory
mkdir /usr/X11R6/lib/X11/fonts/moz
Edit the Makefile to include this directory.

Become "root" on your system and run
make pcf
make install

Edit /etc/X11/fs/conf and add the new directory to the font paths.
Run xset fp+ /usr/X11/lib/X11/fonts/moz/. Restart the browser. Go to the font choosing menu, 
select the Mozilla fonts, and a font size of something like 9 - 12 will be just fine.
