CodeIgniter is a small but powerful PHP framework that serves as a simple and "elegant" toolkit for developers to build fully functional WEB applications. is a more mainstream PHP framework.

The following is a description of the CI framework (Ajax paging, select all, reverse, uncheck, bulk Delete) complete code, as follows:
