Further Reading

The official PHP documentation of how to author classes and streams is pretty sparse. As the saying goes, "Use the force, read the source." That having been said, there are some resources out there. For OOP extension code, the following are some good resources:

• The Zend Engine2 Reflection API, in the PHP source tree under Zend/reflection_api.c, is a good reference for writing classes in C.

• The streams API is documented in the online PHP manual at http://www.php.net/manual/en/streams.php. In addition, Wez Furlong, the streams API architect, has an excellent talk on the subject, which is available at http://talks.php.net/index.php/Streams.
