Brian,
Actually, just to clarify a point, while it is true that the .ZIP file doesn't automatically "install" a PHP.INI file for you, the truth is that there really IS no install. It's quite spartan really. You simply decompress the files and must do all the dirty work yourself by following the steps in README.TXT. For those used to Windows installers, this does really seem a bit antiquated, but I'm sure in time someone will come up with a nice installer to remove the headaches.
Anyway, in that readme file, you'll notice the instructions at one point say
"Installation Notes for Microsoft PWS 4.0
Install the php.ini file and the DLLs as mentioned above.
..."
Well, by reading "above", you'll find there are instructions on where to place the .DLL files, and then in the "Installation Notes for IIS 4.0 and 5.0" you'll see how they talk about
"- If you wish to change any defaults, copy either the php.ini-dist or
php.ini-optimized files into your Windows directory, and rename it to
'php.ini'. You can then modify any of the directives inside it."
But before you misunderstand, I only mention this because "technically" they have given you all the instructions you need. However, I wholeheartedly agree that, especially for those not familiar with some form of Unix (where this kind of "install" is quite common), these instructions leave a bit to be desired. Logically someone installing PHP under Win9x/PWS wouldn't think that "above" meant reading information in the IIS section. Unfortunately the writer of the readme.txt file assumed everyone would just read ALL of the file before proceeding (again, something you get used to doing in the *nix world due to docs not always being up to par with what you might expect). And currently the best way to fully understand PHP is to read...a lot. :-)
I am sure at some point in the future the good folks behind PHP will revise these files to make them more "palatable", and I believe there is already someone out there who has started working on an .EXE installer for PHP to make the install about as easy as any other Windows install. For example, I notice the online PHP manual ( http://www.php.net/manual ) includes a section
http://www.php.net/manual/install-windows95-nt.php
which explains in more detail than the readme how to install PHP. It's a step.
I just hope you don't let the rudimentary nature of the current install process taint your view of PHP's abilities. It really is a cool scripting language and I think you'll find the community support is first rate. And in time I believe PHP will really become, even more than it is already, a key language for website integration. (I'll step off my soapbox now. :-) )
Anyway, good luck to you. Happy coding. :-)
