I'm developing a system using Codeigniter, and it's nearly completion, i didn't went for class diagrams first because it was hard to decide, so i straight away did coding and now i want to draw class diagrams for my project. do you guys know about a tool that i can use for generating class diagrams for my project?
If you want to draw them manually (ie. don't want reverse engineering to generate uml from your PHP source), then StarUML might be useful (if you're using Windows that is, but since you don't mention it I assume you do).
BTW The following question might be helpful too : PHP UML Generator
