Thanks go to reywob for providing us with our newest tutorial that talks about some introductory things to consider with PHPLIB. When I was learning PHPLIB I found them really hard to understand, and I suggest that you only use them if you are experienced. PHPLIB may seem tricky to use if you have never used classes before, because you are always referring to the class, but just persevere. It's worth it in the end! Be sure to check this one out if you have been looking into using PHPLIB on your site.
Update:because of a misunderstanding, we had to remove this tutorial from our section. You can still view it over on users.f2s.com
