Here we are again PHP fans, with your latest edition of phpweekly.com.

The fourth release candidate for PHP 7.2.0 is out this week, to be tested thoroughly and any bugs and incompatibilities reported.

Also, we look at Part 3 of the deploying my Symfony API series, which looks into the whole deploy process from development to production.

The 20th Oscon has been announced for July next year. No further details as yet, but save the date and watch this space!

Plus we have the 2nd episode in the Ask The PHP Experts webinar series, with discussions this week on how to successfully migrate to PHP 7.

And finally, the Lately in PHP podcast team is back, and they are pondering the possibility of being able to override built-in PHP functions.

Enjoy your weekend, 

Thanks
Katie and Ade

Your Unit Test Methods Need Docblocks Too
If you've met me at any time in the previous 20 years and you discussed unit testing with me, chances are pretty big that I'd have told you that your test methods in your unit tests don't really need docblocks, because the test methods would be named in such a way that they were descriptive.

Choose Dependency Injection — If You Can
Some people say, “You don’t need to use dependency injection for everything. Sometimes dependency injection is not the best choice.” It occurs to me that the people who say this are the ones who can’t use it for everything. They say “choose what’s best for your situation”, but their situation precludes the use of dependency injection in the first place.

Drupal Looking To Adopt React
Last week at DrupalCon Vienna, I proposed adding a modern JavaScript framework to Drupal core. After the keynote, I met with core committers, framework managers, JavaScript subsystem maintainers, and JavaScript experts in the Drupal community to discuss next steps. In this blog post, I look back on how things have evolved, since the last time we explored adding a new JavaScript framework to Drupal core two years ago, and what we believe are the next steps after DrupalCon Vienna.

Tutorials and Talks 

Symfony Flex: Paving the Path to a Faster, Better Symfony
Symfony Flex is a modern replacement for the Symfony Installer, and not the name of the next Symfony version. The new Symfony will be called just Symfony 4, and while this tutorial will deal only with the Flex tool, it will mention some Symfony 4 upgrades as well.

Laravel Stats: Code Statistics for your Laravel Projects
Laravel Stats (currently beta) is a package inspired by rake stats that gives you code statistics for your Laravel projects.

PHP-FPM Tuning: Using ‘pm static’ for Max Performance
Lets take a very quick look at how best to setup PHP-FPM for high throughput, low latency and a more stable use of CPU and memory. By default, most setups have PHP-FPM’s PM (process manager) string set to dynamic and there’s also the common advice to use ondemand if you suffer from available memory issues. However, lets compare the two management options based on php.net’s documentation and also compare my favourite for high traffic setups… static pm.

How Can PHP Compare Two Images for Similarity
Some applications need to able to tell if two images are similar in the sense that they show the same thing. The PHP Compare Images Similarity class can be used for that purpose. Read this article to learn about this class and how you can use it in PHP applications for checking if two images are the same or not.

Build a React App With a Laravel Back End: Part 2, React
This is the second and final part of the series on building a React application with a Laravel back end. In the first part of the series, we created a RESTful API using Laravel for a basic product-listing application. In this tutorial, we will be developing the front end using React. We will also consider all the available options to bridge the gap between Laravel and React.

What You Need To Know About Environment Variables with PHP
Environment variables for configuration are today’s best practice for application setup – database credentials, API Keys, secrets and everything varying between deploys are now exposed to the code via the environment, instead of configuration files or worse, directly hard-coded.

How Do I Deploy My Symfony API - Part 3 - Infrastructure
This is the third post from a series of posts that will describe the whole deploy process from development to production. The first article is available here and the second here. In the previous two articles I've covered the steps 1-3 from the schema here below. Before being able to discuss the steps 4-5 we will need to see how to configure the instances properly to be able to deploy our application to a docker-swarm cluster with rolling updates.

Managing Private Dependencies
Using Composer and a private package server is the most efficient way to manage private dependencies with PHP. I recommend using the software as a service, Private Packagist, or Satis, the open source, self-hosted package server. In this article, I’ll show you how to easily set this up for your own projects.

Properly Passing Data from Outer Layers of a PHP Application to the Use Case Layer
Lately, I've been digging a lot in different ways of improving software architecture. Mainly subjects like Clean Architecture, Domain Driven Design, and such. Those topics cover a lot of advanced and complex practices, but today, I want to talk about a simpler subject. What is the best approach to pass data from outer layers of the application (actions, controllers, async jobs, CLI commands...) to services that are part of the use case layer, by taking advantage of some of the practices promoted by those subjects. That's a task which is present in any kind of application, and is very important to get properly done. You usually need to get data from different origins (a HTTP request, the input of the command line...), filter and validate it, and then use it to perform some kind of task. Not doing it in the correct way could cause inconsistencies, or duplications in your codebase.

Creating Datetimes From a Format With a Timezone
I wouldn’t be writing this blog post, if I’d read all the “fineprints” in the PHP manual. Alas, here we are.

How To Use Caddy with PHP and Docker
Caddy is an excellent HTTP/2 web server with automatic HTTPS. The configuration is simple and approachable, providing secure defaults and self-contained binaries that run on every platform. I have found Caddy to be my go-to server for running PHP Docker containers in production. Using the official PHP-FPM image, we can run Caddy and start PHP-FPM in the background within the same container. I find that running PHP-FPM and Caddy together simplifies my stack by eliminating the need for FastCGI network communication between something like Nginx and PHP-FPM.

Pretty Print curl -i
My favourite tool for working with APIs is curl and in particular, I like using the -I switch to view the status line and headers too. What I would like to do is pretty print the body if it's JSON or XML so that it's easier to read.

Installing PHP Packages with Docker and Composer
Package management is a method for importing code (often from open source libraries) and keeping dependencies up to date in a software development project. In PHP, we have a couple ways to manage packages, but the dominant choice for modern PHP development is Composer. While you can install PHP and Composer on your local machine directly, in this tutorial we’ll use Docker, which allows us to run PHP and Composer scripts without configuring either on our system directly.
