Kick-Start WordPress Development With Twig: Introduction
Apr 12, 2016 @ 09:14:01

On the NetTuts.com site they've posted the first part of a new series showing you how to combine WordPress and Twig to "kick-start" your development with this popular content management system.

A lot has been written about the future of WordPress, and many believe that it lacks a templating language, especially when platforms like Django, Ruby on Rails, Node.js, Laravel, and even Drupal possess one. Facts like "WordPress powers nearly 25% of the web" make it difficult to question its current PHP-based templating system. But as the modularity in code is still missing, one can ask when the core will have a templating engine.

The good news is right here! The Twig templating engine along with a plugin called Timber can help us write super-clean and modular code in WordPress.

They start with a brief introduction to Twig and a bit of history of where it came from. They also give some reasons of why you might want to use this popular templating engine (besides its popularity, of course). The tutorial then starts in talking about Timber and how it integrates with both WordPress and Twig to render the Twig templates. This first article is more of an introduction to this integration and doesn't contain much in the way of code examples. That will be coming soon in the following parts of the series, though.

Loïc Faugeron:
The Ultimate Developer Guide to Symfony - CLI Example
Apr 07, 2016 @ 10:43:51

Loïc Faugeron has posted another in his "ultimate guide" series of posts around components in the Symfony framework. In this latest post he gives an example of using the command line component with the Console component.

In this guide we've explored the main standalone libraries (also known as "Components") provided by Symfony to help us build applications: HTTP Kernel and HTTP Foundation, Event Dispatcher, Routing and YAML, Dependency Injection and Console. We've also seen how HttpKernel enabled reusable code with Bundles, and the different ways to organize our application tree directory.

Finally we've started to put all this knowledge in practice by creating a "fortune" project with: an endpoint that allows us to submit new fortunes, a page that lists all fortunes. In this article, we're going to continue the "fortune" project by creating a command that prints the last fortune.

He walks through the use of an example repository as a base and shows:

  • the creation of the command class
  • the matching tests to ensure it's working correctly
  • building out the logic to pull in the latest fortunes

They enter the fortunes via the web interface and use the command line to output them as as simple text.

PredictionIO and Lumen: Building a Movie Recommendation App (Part 2)
Apr 06, 2016 @ 14:30:42

The SitePoint PHP blog has posted the next part in their series about using Predictive.IO and Lumen to create a simple movie recommendation application (part one is here). In this second part of the series they build on the environment created in the previous article and start developing the actual application.

In the intro, we covered the basics of PredictionIO and installed its dependencies. In this part, we’re going to build the movie recommendation app.

The tutorial starts with a brief configuration section to ensure you have your API keys configured correctly. Then it gets into the code:

  • Pulling the data from the Movie DB API
  • Creating the endpoint to perform the endpoint
  • Picking random movies to show the user and recording their reactions (like/dislike)
  • Creating the endpoint to recommend movies

Finally they share the configuration to set up the application deployment and train it with some example content you provide through some basic interactions. Finally they help you set up a cron job to train and redeploy the application every five minutes with the latest interaction information.

PredictionIO: Bootstrapping a Movie Recommendation App
Apr 05, 2016 @ 11:22:11

On the SitePoint PHP blog they've posted a tutorial showing you how to use the Prediction.IO server to create a movie recommendation application. Prediction.io is "an open source Machine Learning Server built on top of state-of-the-art open source stack for developers and data scientists create predictive engines for any machine learning task".

In this tutorial, I’m going to walk you through PredictionIO, an open-source machine learning server, which allows you to create applications that could do the following: recommend items (e.g. movies, products, food), predict user behavior, identify item similarity and rank items.

You can pretty much build any machine learning application with ease using PredictionIO. You don’t have to deal with numbers and algorithms and you can just concentrate on building the app itself.

The tutorial, the first part of a series, refreshes some older instructions for getting the Prediction.IO system up and running. He walks you through the creation of an AWS instance for the server a few different ways (Vagrant, Docker, etc). He then talks about the use of the Movie API from MovieDB and the two parts of the application that will be implemented on top of it: a learning phase and a recommendation phase. They show how to use Prediction.io to create the recommendation engine and make the new application on top of it. He helps you install some dependencies to use in the PHP side of the application and briefly explains what they're for.

This wraps up part one of the series. In the second part he starts putting this all to use and creates the PHP functionality to lay on top of the machine learning engine and handle learning and recommendations for users.

SitePoint PHP Blog:
Fun and Functional Programming in PHP with Macros
Apr 04, 2016 @ 10:13:37

The SitePoint PHP blog has a new tutorial posted from author Christopher Pitt continuing on his look at macros in PHP (part one is here). In this new tutorial he gets beyond the basic example he provided in part one and recreate some expressive syntax from Javascript and prefixing strings.

I was so excited about my previous article about PHP macros, that I thought it would be fun for us to explore the intersection of macros and functional programming. PHP is already full of functions, with object oriented patterns emerging relatively late in its life. Still, PHP’s functions can be cumbersome, especially when combined with variable scope rules…

[...] It’s not significantly more code [to append the prefix in PHP vs Javascript], but it isn’t as clear or idiomatic as the JavaScript alternative. I often miss JavaScript’s expressive, functional syntax, when I’m building PHP things. I want to try and win back some of that expressive syntax!

He starts with a quick install of the yay library used in the first part of the series. Instead of the manual prefixing from his first example, he creates a macro that uses the array_map handling to generate the necessary code once the pre-compiler has done its job. He then expands on this simpler solution and updates it to allow for the setting of the prefix string. It gets a little complex but he walks through each step of the way, explaining the code that's added and what it expands out to. The result is a map method that generates a bit of code that's eval-ed to handle the prefixing automatically.

How to optimize performance of the LAMP stack with eZ (Part 1)
Mar 03, 2016 @ 11:43:51

On the eZ blog there's a new post, the first part of a series, showing how to optimize the performance of your LAMP stack with the help of some tuning on the server and software levels.

Nowadays, a website is not only a simple HTML page. Your visitors expect dynamic, personalized information fast and you need a scalable way to deliver content as quickly as possible. This, of course, puts significant pressure on page loads and response time. In this series of posts, we’ll explore eZ’s system architecture and provide recommendations on how you can optimize caching and decrease response time with eZ software.

They then talk about the various pieces of software that make up a typical environment and some tips on optimizing them:

  • Varnish
  • Apache
  • MySQL and MariaDB

Each includes the configuration changes and setup that's helped eZ get the most out of their stack and links to other tools to help you evaluate the performance differences.

Nginx.com:
Maximizing PHP 7 Performance with NGINX, Part I: Web Serving and Caching
Feb 29, 2016 @ 13:55:10

On the Nginx.com site they've posted the first part of a series showing you how to maximize your performance with PHP 7 and this already speedy web server.

PHP is the most popular way to create a server-side Web application, with roughly 80% market share. (ASP.net is a distant second, and Java an even more distant third.) [...] Now the PHP team is releasing a new version, PHP 7 – more than a decade after the introduction of PHP 5. During this time, usage of the web and the demands on websites have both increased exponentially.

[...] This blog post is the first in a two-part series about maximizing the performance of your websites that use PHP 7. Here we focus on upgrading to PHP 7, implementing open source NGINX or NGINX Plus as your web server software, rewriting URLs (necessary for requests to be handled properly), caching static files, and caching dynamic files (also called application caching or microcaching).

They start by looking at why "PHP hits a wall" in its execution in high load situations, stepping through the process it follows to handle each request. They also share some of the common ways PHP developers have combatted these issues including more hardware, better server software and multi-server setups. They then get into the actual tips themselves:

  • Tip 1. Upgrade to PHP 7
  • Tip 2. Choose Open Source NGINX or NGINX Plus
  • Tip 3. Convert Apache Configuration to NGINX Syntax
  • Tip 4. Implement Static File Caching
  • Tip 5. Implement Microcaching

For each tip there's a summary with more information on why they make the suggestion and, for some, how to make the transition happen. In the next part of the series they'll get into reverse proxy servers and a multi-server Nginx implementation to boost performance even more.

Loïc Faugeron:
The Ultimate Developer Guide to Symfony - Dependency Injection
Feb 25, 2016 @ 10:43:57

Loïc Faugeron has posted another of his "Ultimate Developer Guide" series to his site, this time with a focus on the dependency injection component of the Symfony framework.

In this guide we explore the standalone libraries (also known as "Components") provided by Symfony to help us build applications. We've already seen: HTTP Kernel and HTTP Foundation, event dispatcher, routing and YAML. We're now about to check Dependency Injection, and finally in the next article we'll have a look at Console.

He starts with an introduction to the dependency injection pattern by refactoring a request to an API for its status out into classes with different responsibilities. He includes both the code he started with and what he's refactoring to. He thing brings in the Dependency Injection component, shows how to register the different classes and define a YAML configuration with their relationships. He also includes an examples of how to pass in parameters when injecting services, extending the functionality and compile the functionality into static values.
