Help!

First let me make it clear that I am a beginner at this stuff so even simple problems seem to be stumping me. I have installed Apache 1.3.28 and PHP 4.3.3 and am hoping to use them to test web pages that I am planning to develop that will extract data out of mysql (which I have also installed). Apache is working, when it is started I can call for http://localhost and I get the index file from htdocs, no problem. When I start Apache, the line comes up in the dos window Apache/1.3.28 (Win32) PHP/4.3.3 running . . . From this I assume that php is also installed OK and should be working. The problem is that I can't get a php test page to come up. I have created a page called today.php that has the following code which according to a book I have should return a statement with todays date. <HTML> <HEAD> <TITLE>Today's Date</TITLE> </HEAD> <BODY> <P>Today's Date (according to this Web server) is <?php echo( date("l, F dS Y.") ); ?> </BODY> </HTML> The message that I get is Not Found The requested URL /cgi-bin/php.exe/today.php was not found on this server. Why is it looking there, and how can I fix it? If I rename the file today.htm, the text statement comes up, but it doesn't process the php part (which I didn't expect it to, but it tells me the html is working OK)
