Torben Köhn:
PHP Generators – A Guide and Tutorial
Jun 22, 2016 @ 13:45:44

For those that may have heard about generators but aren't too familiar with them or what they do, Torben Köhn has posted a great introduction to them and their functionality.

In my in-depth guide about iterators I talked about what iterators are exactly and how you can use them. At the end I told you that I’ll also write one for generators. Here it is.

First off, if you don’t know what an iterator is and you’d not be able to explain to someone else what it is, you will not have much fun with this because you won’t exactly recognize the use-cases. I suggest you read my iterator-guide first. After this, don’t get scared off by some confusing words used here, I’ll try to clarify every single one.

He breaks up the rest of the post into different sections, each walking you through different aspects of generators:

  • What is a generator?
  • The yield-keyword
  • Iterating a generator
  • Yielding keys
  • Yielding in a loop
  • An infinite generator

He wraps up the post sharing some real use-cases for generators to help you understand them with a bit more practical application (including stacking them, file system handling and co-routines).

Symfony Blog:
Virtual Symfony Hack Day - March 12th!
Mar 08, 2016 @ 13:41:08

On the Symfony blog they've officially announce their latest virtual Symfony Hack Day coming in March (on the 12th). This event is a concentrated effort from the project and developers to come together and solve issues over several hours.

Symfony has always been a project driven by a huge and active community. [...] Because Symfony has a predictable release schedule, we know that feature freeze for Symfony 3.1 will be at the end of this month (March). That makes the next few weeks of development really important!

That's why we've decided to organize an online hack day, and I would love if you'd join us. If you're an experienced contributor, great! If you're new, even better! This hack day will focus on teaching you how to contribute.

The event will be happening March 12th from 3pm to 8pm CET / 9am to 2pm EST and will focus around the #symfony-dev channel on the Freenode IRC network. They'll be focusing on how to get started contributing to the framework including a mini-workshop showing how to triage issues to creating a pull request.

Step by Step Guide to building your first Laravel Application
Mar 07, 2016 @ 09:25:04

On the DotDev.co site they've posted a tutorial showing you how to create your first Laravel application. In their case they show how to create a simple link collection tool to help illustrate the process.

The Laravel framework has experienced exponential growth since it’s initial release in 2011. In 2015 it became the most starred PHP framework on GitHub and has risen to be the go-to framework for people all over the world. [...] My goal with this is to create a guide for those just learning the framework. It is setup to take you from the very beginning of an idea into a real deployable application.

He starts by pointing out some prerequisites you'll need (like a local PHP environment and having PHPUnit installed). He then gets into the first step in any good application, planning, and some recommendations to think about. Once the planning is done, then the real code starts. He's broken it up into a few sections to help make it easier to follow:

  • The first steps (setting up the basic Laravel application)
  • Building a list of links
  • Submitting Links

In each step he also provides examples of tests that can be written and used to ensure your application is working as expected. Templates for the link output and the submission form are also included.

phpschool.io Announced
Feb 04, 2016 @ 12:45:55

A new service has launched in an effort to help teach PHP to those looking to learn in a different sort of way. The phpschool.io site provides you with a series of exercises that walk you through both the fundamentals of the language and a few more complex topics.

PHP School is a set of ever expanding workshops to teach you basic to advanced concepts in PHP. We launch with one workshop: Learn You PHP. [...] Each exercise increases in difficulty, guiding you through the core concepts of PHP.

Currently the tutorials cover topics like "My First IO", separation of concerns, working with exceptions and handling dependencies. The installation of the lessons is as simple as making a composer require call and installing the packages and dependencies required by the tool. They're also actively looking for community contributions to add more workshops to the based on the Learn You PHP package currently included. The training was inspired by what NodeSchool provides for the Node.js language.

Rob Allen:
The beginner's guide to contributing to a GitHub project
Sep 24, 2015 @ 12:08:10

If you've ever wanted to contribute to an open source project but didn't have any idea where to begin, Rob Allen has a few suggestions to help you get started. His guide is a bit more on the technical level than others that talk more about finding a project or community to be a part of, though.

This is a guide to contributing to an open source project that uses GitHub. It's mostly based on how I've seen Zend Framework, Slim Framework and joind.in operate. However, this is a general guide so check your project's README for specifics.

He walks you through a four step process to getting ready to contribute and make that first submission to the project of your choice:

  • Set up a working copy on your computer
  • Do some work
  • Create the PR (Pull Request)
  • Review by the maintainers

Naturally, some of this depends on the process that the project follows to take in new submissions, either from an issues list or just random buxfixes. It's a pretty standard GitHub-centric guide to follow though. He also recommends reading this article from Lorna Mitchell about code reviews and what the maintainers of most open source projects will look for in submissions.

How to create a PSR-4 PHP package
Sep 09, 2015 @ 10:55:01

In a tutorial posted to the Cullit.com site Philip Brown shows you how to create a PSR-4 compliant package that can be installed quickly and easily through Composer. The PSR-4 standard is a part of the set of standards defined by the PHP Framework Interoperability Group (PHP-FIG) to help make it easier to work with libraries and tools across frameworks and platforms. The PSR-4 standard replaces the slightly more complex PSR-0 to define a pattern for autoloading files.

A couple of weeks ago I wrote a tutorial on the general principles behind building PHP packages. In that article I mentioned the PSR-4 standard for creating PHP packages. In this tutorial I’m going to walk you through setting up the structure of a PHP package. By having an agreed upon structure for PHP packages we make our code a lot more interchangeable and reusable for the greater Open Source community.

He starts with the basics, creating a simple "nacho" directory in a git repository and introducing Composer (and the composer.json) briefly. He also talks about the "dotfiles" that are included with the use of Composer including a sample Travis-CI configuration. He then gets into the code and shows how to use namespaces, relate them to the directory names for autoloading and even writing a simple test or two. From there he talks about documentation and, finally, pushing the package up to GitHub and adding it to Packagist for others to download.

PHP Object-Oriented Programming Beginner's Guide
Aug 12, 2015 @ 09:45:14

For those working to move from procedural PHP into a more object-oriented world but may be having some trouble with the transition, the Star Tutorial site has a great beginner OOP in PHP guide you should check out.

They cover all of the basics you'll need to get started with objects in PHP including:

  • classes versus objects
  • visibility
  • inheritance
  • polymorphism
  • interfaces versus abstract classes

Each section is a quick definition and a bit of code to help illustrate the point. This isn't going to be a hand-holding kind of tutorial showing you each step to making an OOP application. Instead, it provides quick, high level summaries of the main OOP concepts to get you on the right road.

Semaphore Software Blog:
Getting Started with Symfony 2
May 11, 2015 @ 10:35:57

The Semaphore Software blog has posted a new tutorial for those wanting to get into the Symfony2 framework and find out what it's all about. In this new tutorial they walk you through some of the basics of the framework and shows you how to get a basic first site up and running.

Symfony 2 has seemingly gained the attention of developers in recent times. Owing to the growing hype surrounding this framework, it is something that you ought to know about. A web application framework formed of reusable PHP components has been termed as Symfony. Symfony 2 is an updated version of this framework, and it enables developers to create websites and web applications with ease and convenience. The individual PHP components that set out to form this framework can be selected as per your design and development requirements. Let’s understand why Symfony is gaining popularity and why it should be used by you.

They start with the download and installation of the current version and where to place the resulting files. They briefly cover each of the main directories in the framework setup including a bit of sample code to illustrate. They then get into the bundling system and how it fits it with the overall ecosystem of your application, diving it up into functional "chunks". They show you how to register, configure and extend a bundle with some of your own functionality. Finally, the tutorial shows how to configure the database connection and run Doctrine to generate the table mappings.

A Beginner’s Guide To Composer
Mar 31, 2015 @ 13:48:55

The Scotch.io site has posted a guide that can help you if you're just getting started in the world of PHP packages via Composer. In this new tutorial Daniel Pataki introduces you to the tool and how to use it to install the dependencies you need.

I’m sure there are plenty of coders out there who are wondering about the benefits of using composer and many who are afraid to make the leap into a new system. In this article we’ll take a look at what exactly Composer is, what it does and why it is a great tool for PHP projects.

He starts with the basics of dependency management, why it would be used in a project and how it automates the installation and integration of 3rd party libraries. From there he helps you get Composer installed and starts in on a sample "composer.json" configuration file. In his example he installs Monolog, the popular PHP logging class. He talks some about how to specify versions, locking down the dependency versions to install and installing "developer only" requirements.
