The SitePoint PHP blog has posted the second part of their look at the PHP-CPP tool and how to use it for developing PHP extensions. In this second part of the series Taylor Ren builds on what was learned in part one and talks more about the OOP features of the tool.
In this part, we further elaborate its OO features. We will mimic a complex number (in the form of 3+4i) class to demonstrate some more useful and powerful sides of the PHP-CPP library.
He walks you though a few changes to the environment files (the .ini configuration file and the Makefile) to set things up. He then gets into the C++/PHP constructor and getters and setters for private class variables, much like PHP's __get and __set. His example shows a set of methods that do some mathematical calculations including one to show the result in a "more friendly way". He includes the code for registering these functions and, finally, the steps to compile, install and test the extension.
