Master Zend Framework:
The Composer Command-Line Essentials
Nov 29, 2016 @ 10:15:52

The Master Zend Framework site has posted a tutorial that seeks to help you get the most out of Composer on the command line with some essential tips beyond just he basics.

I know that a series on Composer might seem odd. But, as Composer’s been a part of PHP for so long now, I feel that it’s something which most of us take for granted. It’s revolutionised the PHP landscape, making it easier than ever before to build great software in PHP. But do we really know how to get the most out of it. For that reason, I’ve created this series, so that you level up your skills and really get the most from it.

In part one of this series, I’m going to take you through Composer’s command-line. I’ve cherry-picked a key subset of the command-line options, and focused in on key switches, so that you can do more than you already can.

He skips over the basic "require", "install" and "update" handling covered in many other tutorials and instead covers:

  • project creation
  • the "show" command to list installed packages
  • "remove" to drop a package from the current dependencies
  • using "depends" to see package dependencies
  • finding outdates packages with (appropriately) the "outdated" command
  • seeing suggested packages with "suggest"

For each item on the list there's an example of the command, what kind of options is allows and, for some, the output generated as a result.

SitePoint PHP Blog:
Modding Minecraft with PHP – Buildings from Code!
Oct 20, 2016 @ 10:58:47

The SitePoint PHP blog has posted another Minecraft-themed tutorial from Christopher Pitt, this time explaining how you can mod Minecraft with PHP without having to learn Java.

I’ve always wanted to make a Minecraft mod. Sadly, I was never very fond of re-learning Java, and that always seemed to be a requirement. Until recently. Thanks to dogged persistence, I’ve actually discovered a way to make Minecraft mods, without really knowing Java. There are a few tricks and caveats that will let us make all the mods we desire, from the comfort of our own PHP.

The method he's come up with talks directly to the Minecraft server (using AMPHP) to communicate via a RCON connection and place items in the world based on messages from the user. He uses code created previously to listen to the logs and grab the messages from the user. With this data he then sends a "blueprint" over the RCON connection with a set of coordinates of locations to build the blocks. The end result looks something like this.

Building Your Startup With PHP: Email Commands
Sep 15, 2016 @ 11:22:40

TutsPlus.com has continued their "Building Your Startup with PHP" series in this latest tutorial covering the use of email commands in their "Meeting Planner" example application.

This tutorial is part of the Building Your Startup With PHP series on Envato Tuts+. In this series, I'm guiding you through launching a startup from concept to reality using my Meeting Planner app as a real-life example. [...] In the last tutorial, we began emailing meeting invitations which included numerous links for participants to respond, i.e. view the meeting page, accept all places and times, reject a place or time, etc.

In this tutorial, I'll review how I chose to construct and process those links in a secure, functional manner.

He then starts in on the idea of "commands" explaining a bit about what they are and what kind of commands are needed for the planner application. Code is included to create some of these commands and how to integrate them into the rest of the Yii-framework based application.

Robert Basic:
Using Tactician in a Zend Expressive application
Jul 14, 2016 @ 10:41:10

In this recent post to his site Robert Basic shares some of his experience integrating the Tactician command bus library into a Zend Expressive-based application.

I spent some time connecting the dots last week, so I decided to put together an example on how to get started with using Tactician in a Zend Expressive application. The example itself is not really useful, but it does show how to setup the dependencies and get started with these two libraries.

He briefly introduces the two pieces of technology here and then "dives in" immediately to the integration. He shows how, using the Zend Expressive skeleton application, to expand on the default "ping" endpoint and add in the Tactician library (and another library that makes it easily integrate with the DI container). He updates how the "ping" action is made in the routing, making it go through a factory. He then brings Tactician in, setting up the command bus and a simple "ping" command for the bus to use in handling the requests to the /api/ping endpoint. Complete code and explanations of each part are included in the tutorial to help you follow along.

Stefan Koopmanschap:
Command or Controller
Jun 20, 2016 @ 12:04:18

In a post to his site Stefan Koopmanschap takes a look at the technical term "command" and tries to clear up some of the confusion around its use and how it differs from the idea of a "controller".

A couple of weeks ago while walking towards lunch with Jelrik we were having a bit of a discussion about the use of the term Command. Not long before that, Jelrik had asked a question about naming of Commands in our Slack channel, which led to some confusion.

He starts off by defining what a command is and why it's called a "command" instead of a controller (hint: it "just works" with the Symfony Console). He then gives an example of a command in a Symfony bundle structure and how a CLI "controller" can extend the Command and automatically be integrated into the command structure.

Loïc Faugeron:
Towards CQRS, Command Bus
May 12, 2016 @ 12:07:21

Loïc Faugeron has made a new post to his site talking about moving towards CQRS and Command Bus architecture in PHP applications.

By following the Command / Query Responsibility Segregation (CQRS) principle, we separate "write" logic from "read" logic. This can be applied on many levels, for example on the macro one we can have a single "Publisher" server (write) with many "Subscribers" servers (read), and on a micro level we can use this principle to keep our controllers small.

However, transitioning from a regular mindset to a CQRS one can be difficult. In this article, we'll explore the "Command Bus" pattern, to help us to get the Command (write) part right.

He starts with an example of a "create profile" happens and all logic lives in the controller. He then gets into the basics of the Command Bus handling and how the concept of "middleware" relates. He then shows how to migrate over to the Command Bus handling in his controller example, creating a CreateNewProfile command (with unit tests) and its handler. He then refactors the controller to put it to use. He points out that the initial version is tightly coupled to Doctrine so he refactors it too via some simple interfaces.

How to Create a Slack Interface for Your PHP Application
Apr 21, 2016 @ 10:12:04

On the TutsPlus.com site they've posted a tutorial helping you connect your PHP application with Slack allowing for both the sending of content to your Slack channel(s) but also responding to "slash" commands.

If you've been following the development of office communication tools in the past year or so, I'm sure you've heard plenty about Slack. [...] As developers, we are in a good position to jump on the trend and think about ways we can use Slack as a chat-based user interface for our applications.

That's why, in this tutorial, you will learn how to get started with integrating your PHP application to Slack, by making it post messages to a Slack channel and respond to slash commands.

They start with a "bare bones" setup that will get you up and running and sending messages to your Slack instance. Their example takes in a string and sends it along through a custom Slack application. They walk you through the steps to create this application on the Slack side and this example code to make the connection and send the message. The tutorial walks you through all of the provided code and helps you get your OAuth credentials in place to secure the connection.

With this basic functionality in place you can then build on top of it and define "slash" commands that request a URL. Their example "tells a joke" in the channel making the request.

Marko Pavlovic:
Restful Commander
Mar 23, 2016 @ 11:55:10

In this post to his site Marko Pavlovic talks about REST APIs, some of the non-CRUD (create, read, update, delete) operations that need to be performed and how the Command design pattern can help.

We’ve all been here: the data model has been designed, and we have the entities and relationships implemented. It is finally time to code up the business logic and we are faced with solving these problems: The actions we want to implement on a particular model are not part of the good old CRUD (Create, Read, Update, Delete) operations, and we need to make a lot of non-standard controller actions, and routes. [Also] the actions we want to implement do not belong to a any model, and we have to create a new controller just for the "API".

He gives a more concrete example to illustrate the problem using "sites", "visits" and a desire to add analytics functionality using each's data. He points out two common actions taken when something like this comes up: either new methods on the pre-existing controllers or possibly making a new controller to handle it. Instead he suggests using the Command pattern to handle requests themselves as self-contained items. This gathers all the logic needed in to one place and the Report instance can then be used as-is by the response that needs to render the results.

Geert Eltink:
Zend-Expressive Console CLI Commands
Feb 12, 2016 @ 11:21:15

In a new post to his site Geert Eltink shares how he added console command support to Zend Expressive, a PSR-7 framework from Zend that recently hit it's v1.0 mark.

zend-expressive does not come out of the box with a console for handling cli commands. However it's easy to add this and make full use of the container and its dependencies.

He uses the Symfony console component to handle most of the "heavy lifting" with the command line interaction, pulled in via Composer. He shows the process for getting the component installed and how to create the "bootstrap" file needed to build an instance of the Application class. He follows this with a simple "greeting" command including the configuration to add a few arguments and output the simple "Hello" message. He then creates the functionality to wire it in to the Zend Expressive application and gives an example of it in use.

Freek Van der Herten:
Some Laravel Homestead tips
Jan 18, 2016 @ 12:27:30

Freek Van der Herten has a post to his site sharing some Laravel Homestead tips you can use to optimize and customize your current Homestead installation.

Homestead is a pre-packaged Vagrant box that includes a good development environment. It was made and is maintained by Taylor Otwell, the creator of Laravel. In this post I’d like to share some tips regarding this box.

His list of tips includes:

  • Map all sites at once
  • Use a bash function to work with a globally installed homestead
  • Map your dotfiles directory

Each tip comes with a bit of code/configuration changes to make to be able to use the functionality and configure the instance correctly.
