Overview of this book

This book will get you started with the latest benchmarking, profiling and monitoring tools for PHP, MySQL and JavaScript using Docker-based technologies. From optimizing PHP 7 code to learning asynchronous programming, from implementing Modern SQL solutions to discovering Functional JavaScript techniques, this book covers all the latest developments in Faster Web technologies. You will not only learn to determine the best optimization strategies, but also how to implement them. Along the way, you will learn how to profile your PHP scripts with Blackfire.io, monitor your Web applications, measure database performance, optimize SQL queries, explore Functional JavaScript, boost Web server performance in general and optimize applications when there is nothing left to optimize by going beyond performance. After reading this book, you will know how to boost the performance of any Web application and make it part of what has come to be known as the Faster Web.

Multithreading with pthreads


POSIX Threads, better known as pthreads, is a library that allows a computer program to execute multiple processes or threads concurrently by forking child processes from its parent process. The pthreads library can be used in PHP, making it therefore possible to fork processes in the background while executing something else simultaneously. Thus, multithreading is another way to cope with latency in I/O calls. In order to accomplish this, we will need a thread-safe version of PHP with the pthreads extension enabled. In our case, we will use a Linux for PHP container that is running a Zend thread-safe (ZTS) version of PHP 7.0.29. Open a new Terminal window, cd into the project's directory and enter the following command:

# docker run -it --rm \
> -p 8282:80 \
> -v ${PWD}/:/srv/fasterweb \
> asclinux/linuxforphp-8.1:7.0.29-zts \
> /bin/bash

Once you are done entering this command, you should see the following information if you enter the php -v command...
