High Performance Solution for PHP7
This document provides an overview of high performance solutions for PHP developed by the author. It summarizes several PHP extensions created by the author including Yaf (a PHP framework), Yar (an RPC framework), Yac (a cache), Yaconf (a configuration container), Taint (for security), and contributions to Opcache (an opcode cache and optimizer). It describes how these extensions have helped improve performance at companies like Weibo by improving response times, reducing server needs, and allowing for concurrency.
