Welcome, PHP fans, to this weeks edition of phpweekly.com.

Plenty of PHP releases to start with this week, including PHP 7.0.0 Beta 3 and PHP 5.6.12. All are available now and recommended for immediate upgrade.

Also this week, Symfony has announced that all its maintained branches are 100% compatible with PHP7, in anticipation of its imminent release.

We have the final part in the series on how to create a custom payment method module in Magento, with a demonstration about the remaining checkout process.

Plus SymfonyCon 2015 has been announced for December, in the Symfony hometown of Paris.

And finally, the PHP Round Table Podcast this week looks at developers' experiences with documentation, and how it can be improved.

Articles

Appserver – a Production-ready PHP-based Server
It has been just over a year and a half since the team at TechDivisionGmbH were interviewed on SitePoint about their paradigm changing PHP application server system called appserver.io. At the time of the interview, appserver was just breaking out as an alpha. Since then, a lot has happened and appserver is now GA as a production system, currently in version 1.0.6, with version 1.1.0 on the horizon.

An Homage To Strict Coding
Strictness is not a specific design pattern or best practice, it’s much more general than that. Strictness is about constantly looking for ways to reduce ambiguity in a design. Coding languages and software tools offer us all sorts of opportunities to do that - it’s up to us to take advantage of them.

Symfony Achieves 100% PHP7 Compatibility
PHP7, the new version of the programming language Symfony is built with, will be released at the end of the year. The recent release of its third beta has brought us another step closer to the final stable release. During these past few months, we've been working very hard to achieve full PHP7 compatibility. This effort accelerated during the past weeks and we're glad to announce that all Symfony maintained branches are now 100% compatible with PHP7.

Stop Returning Arrays (Use Objects Instead)
When returning large amounts of data, it can be common to turn to a built-in PHP data structure: the array. But in object-oriented code, arrays make poor object-to-object data transfer mechanisms. Object-oriented programming is, and should be, focused on objects. That means that each array should be converted into an object, and collections too.

Tutorials and Talks

Resumable File Upload (Part 2)
In Part 1 of this series, we went through the steps to implement the front part of the application. Here in Part 2, we will work on the backend system.

Create a Custom Payment Method Module in Magento: Part Three
In this series, we're working on how to create a custom payment method extension in Magento. In the previous two parts of this series, we created a basic module to provide the back­-end configuration for our custom payment method and list our custom payment method in the checkout process. In the last part of this series, we'll create a demo payment gateway page to demonstrate the remaining checkout process.

Writing Highly Readable Code
We are always told that commenting our code is important. Without comments, other developers will not be able to understand what we did and our future selves will recoil in horror when doing maintenance. Readable code, however, is not only about comment text. More importantly it is about the style, structure and naming. If you get into the habit of writing easily readable code, you will actually find yourself writing less comments.

Why is Slim 3 Not So Slim Anymore
There is a common misconception that Slim 3 has plenty of files and is no longer slim. Slim 3 does indeed contain more files than Slim 2, and this has been the result of being more flexible and moving away from the Not Invented Here (NIH) philosophy. Installing Slim 3 through composer will install all its dependencies, and when doing a PHP file count you will notice we have doubled in file count. 

Deadlocks Are Not Dangerous. Just Try Again.
Set the appropriate isolation level, wrap a unit of work into a transaction and do expect it to fail. Therefore this pattern is recommended.

Functional HTML Rendering with PHP
When you’re working with a programming language that doesn’t have templating per default and you’re not in the mood - or don’t see the need - for templating, your first course of action is to write something to obviate having to print and concatenate everything. 

How to Create a Mock REST API for Testing In nodejs
There is a frequent requirement during api development to create a mock api quickly so that other team members can use the same to test their respective part of the project. For example, front-end developers might need the api endpoints to test their designs. Rather than wait for the complete api to be finished, developers can create a mock api quickly for testing. This nodejs module by typicode helps front-end developers who need a quick back-end for prototyping and mocking REST apis.

How to Create a Simple PHP CMS with SEO Friendly Links
Nowadays search engines like Google value more and more the user experience provided by the sites to rank their site pages well. So, SEO (Search Engine Optimisation) often means making the sites more user friendly. One aspect that contributes to Web site pages being ranked well is to have friendly URLs that allow the user to know what pages are about just looking at the URLs. Read this tutorial to learn how to create a simple content management system that uses user friendly URLs for the content pages, so you can implement in your own projects without having to use other large CMS systems.

PHP Object-Oriented Programming Beginner's Guide
Class is like your house blueprint. Before your house is constructed, there is a house blueprint. It is not an actual house, but a plan how this house will look, how many rooms it will have and so on. Then the house will be constructed by following the blueprint exactly. In this analogy, the house blueprint is a class and your actual house is an object. We can have unlimited objects of a class, just like we can build unlimited exact houses by following the same house blueprint. 

Save Memory by Switching to Generators
Since the release of PHP 5.5, we now have access to generators. Generators are a pretty cool language feature, and can allow you to save quite a bit of memory if they are used in the right places.

Introduction to Elasticsearch in PHP
In this tutorial, we’re going to take a look at Elasticsearch and how we can use it in PHP. Elasticsearch is an open-source search server based on Apache Lucene. We can use it to perform super fast full-text and other complex searches. It also includes a REST API which allows us to easily issue requests for creating, deleting, updating and retrieving of data.

Dealing with Exceptions in a Laravel API Application
Exceptions are a very important method for controlling the execution flow of an application. When an application request diverges from the happy path, it’s often important that you halt execution immediately and take another course of action. In today’s tutorial I’m going to show you how I structure my Laravel API applications to use Exceptions.

Continuous Deployment Environment with Docker, AWS EB and Codeship
This is the first part of a series of tutorials in which we will configure a virtual machine, join the configuration to the project, and automatically deploy and connect everything together with a continuous delivery tool.

PHP Round Table Episode 26 - Documentation & Developer Experience
Documentation can make or break a project but it's often completely overlooked until the very end. And if we don't think about how developers will interact with our project before writing our opening <?php tag, we could end up with a very ugly API. We'll discuss some strategies we can take to improve the overall developer experience with "good" documentation and clean APIs.
