Hi
I am going to start a PHP project soon ... a CMS designed specifically for my clients focusing on simplicity, etc.
What I am looking for is a well established project that I can refer to... not plagiarise or copy, merely something to learn from. I want to refer to this project to see what hurdles they had to overcome, how they dealt with issues such as code portability and the like.
I'm not looking for answers like: 'Why rewrite a CMS... look at Drupal/Joomla/etc'. But I am looking for a guide to look into and educate myself. I want to get it right, from the beginning. Our old custom CMS (not written by me) is coded quite amateurishly and changes/addons/extending is much more difficult than it should be. Security is also light to non-existent.
I was going to look at Wordpress, but thought I'd ask here first. Feel free to recommend even a personal project, if you feel you have a well designed and coded application. Remember I just want something as a guide. Links to tutorials or articles are fine too.
I appreciate your time. Thanks.
Note: If I feel I've created something useful, I'll be happy to release it back to the open source community. Though it'll be just another PHP CMS :P
The site will be coded to work optimally on Linux with Apache, and PHP 5.
