Q: What popular modules does php have? Module .... I understand it too well. Due to the php module's php environment concept, the php environment consists of multiple modules. The module is used for php to implement certain functions, such as the gd library, for image operations.

I thought it was a code block or code reuse. I went to www.phpclasses.org for the php class. There are two official projects called PEAR and PECL, which provide a lot of Function Support, I recommend that you check the zendframework.
How to use existing php modules? Add to webpage? Copy the source code of the message board, and add a link to the bbs directory to the homepage of the bbs directory.
