New features in PHP 7.1
Feb 13, 2017 @ 10:57:45

The PHP 7.1.x releases are some of the latest versions of the language. There's plenty of new features that came along with this new release. In this new post to his CodeDiesel blog Sameer Borate looks at some of these new features (including code snippets to illustrate).

The PHP development team announced PHP 7.1.0 on 01 Dec 2016. This release is the first point release in the 7.x series. There are a few features – like the void return type – which have been introduced. Below are a few new selected features in PHP 7.1.

In the post he covers:

  • void functions (return type)
  • nullable types
  • symmetric array destructuring
  • class constant visibility

For each, code samples are provided and some of the benefits (and limitations) that come along with them.

SitePoint PHP Blog:
How to Make Modern PHP More Modern? With Preprocessing!
Feb 03, 2017 @ 11:20:47

The SitePoint PHP blog has posted another tutorial from author Christopher Pitt sharing another one of his "interesting things" you can do with PHP. In this latest article Christopher returns to the idea of "macros" to help with some pre-processing in PHP applications and, ultimately, creating a new language feature without some of the usual overhead.

Let’s have a bit of fun. A while ago, I experimented with PHP macros, adding Python range syntax. Then, the talented SaraMG mentioned an RFC, and LordKabelo suggested instead adding C#-style getters and setters to PHP.

Aware of how painfully slow it can be for an outsider to suggest and implement a new language feature, I took to my editor…

He starts with a brief refresher on macros to do some pre-processing on PHP scripts and allow you to make custom language features that then get interpreted into valid PHP (often with some interesting eval tricks involved). He starts by building a "base" to add in the C# style getters and setters in a special format inside of a class. He includes the macro definitions to set this up and the result once it is passed through the "yay" precompiler. To get around having to run that precompiler every time manually, he creates a custom autoloader to do the job dynamically. He then takes this logic and packages it up so it can be easily installed as a Composer dependency. With this structure in place, he moves on to the creation of a new language feature - the actual functionality for the getter/setters. He ends the post with a screen capture showing the language feature in use and some of the interesting things you can do with it.

Nikola Poša:
On structuring PHP projects
Jan 17, 2017 @ 10:17:18

Nikola Poša has shared some advice form his own experience on structuring PHP projects and some alternatives to some of the typical structures seen across many packages and applications.

An indispensable part of every programming project is how you structure it, which involves organizing files and sources into directories, naming conventions, and similar. As your application grows, so does the need for structuring it in way that it is easy to manage and maintain.

In most cases, structure of an average PHP-based application is dictated or influenced by the framework that is being used, which is something I'm opposed to. With no intention to be intrusive and without any bias towards specific framework, I'll share with you how I think about organizing my PHP projects.

He starts with a common directory structure seen in a wide range of projects in a framework agnostic way. He mentions the PHP-PDS project that tries to promote this same structure but also provides some alternatives:

  • grouping by archetype
  • grouping by feature
  • splitting out domain and general-purpose code

For each he provides an example of the directory structure and explains the rationale behind it a bit.

Building Your Startup: Ajax for Meeting Times and Places
Jan 02, 2017 @ 13:10:42

The TutsPlus.com site has posted the next in their "Building Your Startup" series of tutorials covering the use of Yii2 to create a calendaring application. In this new part of the series they continue migrating some functionality over to use an Ajax-powered system, reducing the need for page reloads.

Last week, I delved deeper into Ajax to transform the meeting scheduling experience into a fully ajaxified model and eliminated the need for page refreshes. I got about halfway, focusing mostly on the straightforward elements.

In today's tutorial, I'll guide you through the more complex content panels that required a lot more troubleshooting, research, debugging, brainstorming, and recoding. [...] I'm also going to show you how I used Google's Chrome browser developer console to help me identify the broken areas—which can be especially difficult when working with Ajax between PHP and JavaScript. It's like light at the end of the tunnel of darkness.

The tutorial then walks through the updates needed to move over various pieces of functionality to the Ajax-driven model:

  • adding meeting participants
  • adding dates and times
  • adding meeting places

There's also a few screenshots included of the Chrome developer console and what some of the example request/responses look like, helping you debug your own development work.

Update to queue workers in Laravel 5.3
Dec 21, 2016 @ 09:47:38

Continuing his series about new functionality in Laravel v5.3 Matt Stauffer has posted this quick article covering updates to the queue worker functionality.

Queues are one of those tools in Laravel that everyone knows is there, but very few people understand deeply. It's understandable--Laravel is often the first place folks have run into queues, and to be honest, they're not simple.

Thankfully, very little has changed on a user-facing front with regard to how queues work in Laravel 5.3.

One of the main updates is that the "listen" command is now "work" and the action then runs as a daemon by default instead of requiring the command to be long-running. He talks about the difference in this shift and how something like Supervisor can now be used to manage the daemon (including some documentation specific to Laravel). He finishes the post looking at what has changed "under the hood" and the benefits the changes bring.

Leonid Mamchenkov:
Feature Flags in PHP
Dec 20, 2016 @ 09:16:29

In a new post to his site Leonid Mamchenkov talks about feature flags, a handy tool you can use in your application to enable/disable features and or risky changes in your code allowing you more production-level control.

Today edition of the “Four short links” from the O’Reilly Radar, brings a quick overview of the different feature flag implementations. It touches on the following: Command-line flags, with the link to gflags, A/B flags, Dynamic flags [which are more difficult] and more complex systems.

I’ve dealt with feature flags before, but never found an elegant way to scale those. [...] These days, something more robust than that is necessary for some of the projects at work. Gladly, there are plenty of available tools to choose from – no need to reinvent the wheel.

He talks about some of the challenges that he had in his own feature flag implementation including naming of the flags and where the flags should be placed. He then links to the PHP Feature Flags site and various PHP libraries that implement feature flags slightly differently and cover cookie-based, IP-based and URL-based features. He ends the post by pointing out that the lack of feature flags in any complex application is usually considered toxic when it comes to being able to scale an application correctly.

Building Your Startup: Issue Tracking and Feature Planning
Dec 02, 2016 @ 12:56:23

TutsPlus.com has continued their "Building Your Startup with PHP" series today with this latest tutorial covering the creation of an issue tracking and feature planning process with the help of the Anana service.

Even for a one-person startup, it helps to have more than a spreadsheet (or paper) to track issues, ideas, and bugs. A few years ago, I'd used Lighthouse for my grant-funded NewsCloud Community Starter Project. Last year, I'd been introduced to Asana during a consulting gig.

[...] Eventually, I found my way and discovered the tool works well whether you're working with a variety of people or just solo. In today's episode, I'll walk you through how I began using Asana for Meeting Planner. I use Asana not only to track issues but to organize them and plan for the future. I also use it to track and process bugs.

He walks you through getting started with the service (they have a free tier) and how to set up your first project. He includes examples of task creation, tagging tasks and tracking bugs right inside the service. He then uses it to create a "release plan" for the next version of the Meeting Planner application. He wraps up the post talking about what's next on his side for the Planner application and its funding goals.

Nov 25, 2016 @ 13:32:29

On the Kinsta blog there's a post detailing some of the new features that are coming in the next release in the PHP 7 series - PHP 7.10.

The newest version of PHP – 7.1.0 – is already at RC6 (Release Candidate 6) status, which means it will be out soon. After a huge update that took PHP from 5.6 straight to 7.0 increasing speeds considerably, PHP is now focusing on core language features that will help all of us write better code. In this article I’ll take a look at the major additions and features of PHP 7.1.0 which is just around the bend.

Their list of items includes:

  • nullable types
  • iterable and void returns
  • the use of keys in lists
  • number operators and malformed numbers

Each item in the list includes a brief description and some example code show the feature in use where it makes sense. If you're not overly familiar with what's coming in PHP 7.1 this is a great guide.

PHP 7 performance improvements (1/5): Packed arrays
Nov 17, 2016 @ 11:06:53

On the Blackfire.io blog a new tutorial has been posted by Julien Pauli looking at some of the features of PHP 7 and how they relate to the overall performance in this latest major version of the language. In this first post in the series Julien talks about packed arrays.

This blog series will show you what changed inside the Zend engine between PHP 5 and PHP 7 and will detail how you, as a developer, may effectively use the new internal optimizations. We are taking PHP 5.6 as a comparison basis.

[...] Packed arrays is the first great PHP 7 optimization. Packed arrays consume less memory and are a bit faster in many operations than traditional arrays.

He gets into the specifics of how the packed arrays work, mentioning the internal optimization the language does, requiring no intervention in user-land code. He shows the difference between the PHP 5.6 performance and PHP 7 using the Blackfire.io tool - a difference of about a 70% gain.

5 New Features In PHP 7 That You Should Have A Look At
Oct 19, 2016 @ 09:43:05

If you've heard about the release of PHP 7 but aren't quite sure what it has to offer, check out this quick post on the StartTutorial site giving you a "top five" list of things this new version of the language has to offer.

But you must be wondering why PHP named its latest release PHP 7 and not PHP 6. Reason behind it is that, many of the PHP 6 releases were already implemented in PHP 5.3 and later, there was not really a proper reason just to change the name. What I am trying to say here is that we haven’t missed anything. Just to avoid the confusion with a dead project, PHP's latest release was named to PHP 7.

Is This Hype Valid for PHP 7? What It Actually Brings Forth for the Developers? Hop on and let’s take a deeper dive. Let's check out what new features PHP 7 has to offer. And what improvements those features will bring forth.

Their top five list covers some of the major improvements in the language:

  • Speed Improvement
  • Implementation of Type Declarations
  • Implementation of Error Handling
  • New Operators
  • CSPRNG Functions

There's a bit of explanation of each item on the list but you'll definitely want to refer to the PHP manual for more details and specifics on what changed in PHP 7.
