PHP does not seem to be configured correctly

Good morning,

I hope someone can help be get started;  I'm at ground zero and not
making any progress.  The goal is MySQL with PHP support.  I have a
simple test page which says --

<p>Hello from HTML.</p>
<?php echo "PHP says Hi, too";
phpinfo();
?>

-- but only the HTML line appears.  There seems to be no connection
between the page and PHP.

The system is Windows 98.  I've downloaded php-4.3.8-Win32.zip.  I'm
aiming at using the CGI executable version of PHP (php.exe).  The
distribution file was extracted to c:\php, and the extension dlls are in
c:\php\extensions.  The php.ini resides in c:\Windows\ and has been
edited to show extension_dir = "c:\php\extensions" (I've also tried
c:\php but to no avail).  The dlls in the distribution were copied to
c:\windows\system.  I downloaded and ran MDAC 2.8 from Microsoft. The
Registry shows a path to c:\php\php.exe.

I can't seem to find anything in the archives.  Can you tell me what's
missing?  Should I start over and try the Windows PHP installer? And if
so, how to do that?  ...I got an error of "The file you requested
(php-4.3.8-installer.exe) is not found on this server."  <sigh>

Thanks.

Harold
