I'm giving a PHP course next semester (3 hours all saturdays for 22 weeks) and I just realized that PHP 5.3 is coming very soon (2 days now!). So, my plans of teaching PHP 5.2 are starting to change, and I think it's a good idea to teach them 5.3 already.
While the majority of the students use Windows, I'm aware that a vast amount will be using Ubuntu/Debian (and some use Gentoo, Fedora and Arch) distributions of Linux, so I'm hoping there won't be too many problems on installation. I don't want to waste the entire first class fixing installation problems, because that kills the student's motivation. The course starts on August, but I'm preparing it during the last two weeks of July. You think that installation packages will be bulletproof by then? Or should I just teach 5.2 and wait for another semester before starting on 5.3? I mean, most hosts will remain with PHP 5.2 for the rest of the year, so I'm a bit confused on what I should do. I'm just a university student that wants to spread PHP, for I've been using it for many years now =) Thanks for the advices, Mamsaac
