Sara Golemon calls herself a terminal geek. She has been involved in the PHP project as a core developer for almost 4 years, and she is known to be involved in PHP in a slightly different way than others, which you can take as a compliment or a criticism. She works as a programmer or analyst at the University of California. Sara is also the developer and main maintainer of more than a dozen PECL extensions. She also develops and maintains libssh2, a non-PHP related project that provides convenient access to the SSH2 protocol. At the time of writing, she was actively involved in migrating the byte stream layer for Unicode compatibility in PHP 6.
The above introduces the author of "Extending and Embedding PHP", including aspects of the content. I hope it will be helpful to friends who are interested in PHP tutorials.
