On the SitePoint PHP blog today Taylor Ren continues his look at using the PHP-CPP library to help build custom extensions. In this latest post he sheds some light on some more advanced topics.
In my earlier articles, I have introduced the PHP-CPP lib to create an extension for PHP using C++ (first article and second article). In the latter, I demonstrated a bit of the OO side of writing a PHP extension with a Complex class doing complex number manipulations. That introduction is not complete as the main focus of that article is more on the demonstration of the OO capability of PHP-CPP, not on the OO implementation details. In this article, we will further drill down the Complex lib development, adding more member functions, and addressing some advanced topics in writing a PHP extension with OO features using PHP-CPP
He breaks up the advanced topics into sections, providing code examples for each:
- Returning this pointer in C++
- Returning a Complex object pointer
- Exposing the __toString magical method
- Chaining member function calls
- Exception throwing and handling in PHP
With the code in place, he then shows how to test all of the new functions you've added with a bit of simple PHP code.
