Do not under any circumstances try to do this from scratch. :-) Use an existing framework like Zend Framework or CakePHP or a CMS/framework hybrid like Drupal or a dedicated app for billing and processing. It will save you months of work, and countless security holes.
Even if you don't use it directly, studying a large existing system like that will open your mind to better ways of thinking. I only half-joke when I say that everything I know about PHP I learned from Drupal. :-) On Monday 01 June 2009 11:50:36 pm Angus Mann wrote: > Hi all. > > I'm working on a PHP project for my own personal business use.
