Tutorial
This chapter introduces several ideas and concepts of Plib_XH which can be useful to develop CMSimple_XH plugins. The tutorial requires some basic knowledge of PHP and Web development in general, and also some working knowledge of developing CMSimple_XH plugins. If you have never developed a CMSimple_XH plugin before, consider to walk through the dated Plugin Tutorial. Most of the information in that tutorial still applies, although you should take any recommendations there with a grain of salt.
The tutorial consists of several chapters which eleborate on individual concepts of Plib_XH. Those chapters are based on excerpts of old CMSimple plugins, to show some real world examples, and to demonstrate how such plugins could be developed nowadays using Plib_XH and contemporary PHP versions.
Note that the tutorials do not contain complete code samples; for brevity, only code snippets are presented.
