Well, after recently coming from working on a larger c project, I built the whole game using Dreamweaver's template system, Fireworks to generate small optimized gifs, lots of javascript to do things that aren't exactly needed by php, on-the-fly/dynamicimage loading etc, and the rest of the actual php is stored in 9 include files, with 100% being functions and in-line code.
Its rather sloppy, at least in style, but I've tried to keep cpu usage to a minimum. The only thing I'm worried about is the 4-7 mysql queries per page. Though, I kept the data each calls pretty minimal, querying mostly single rows when needed, etc.
Uhm, I guess what's worrying me is that I stumbled upon a ton of articles describing OO and php, and I'm not to sure I'm happy with working with OO and php... This is me just trying to justify the fact that I can achieve just as much speed through includes and functions.
BTW, I did a loop through the inventory page 50-100 times every second for five minutes, and the average page load went up to around 0.23-0.25 seconds.
Thanks for any/all feedback.
BTW, I'm keeping this closed source, I doubt anyone would want my code anyway, lol.
*** PS> I'd been generating the site's menu dynamically, with the data being stored in the database, just went through replacing the menu with a static menu (the menu didn't really have any reason to change), and downed the load time on all the pages to below .06, with the high loads producing around .1 second load times....
