Q. What are some of the more popular modules in PHP?

Say module .... I too understand, because PHP module PHP environment concept, PHP environment by a multi-module, module for PHP implementation of certain functions, compared to the GD library, used to achieve picture operation.

I think say code block, or refer to reuse code, find PHP class to www.phpclasses.org, the official has 2 projects, called pear, also called pecl, which provides a lot of functional support, as well as brothers have been introduced, I suggest to see zendframework.

How do I use PHP modules already? Is it added to a webpage?
