May 7, 2018 — ¿Sabes que WordPress recomienda usar la ultimísima versión de PHP? Sí, la 7.2. ¿Y sabes porqué? Pues con esta charla te vas a enterar de dos de los proyectos que están poniendo al día el núcleo, plantillas y plugins de WordPress para mejorar su rendimiento y la calidad del código.

Con “Codename Servehappy” aprenderás todo lo que hay que saber sobre la “WordPress PHP education initiative”, y con “Project Tide” cómo mejorar la calidad de tu código para hacerla estándar con otros colaboradores y para que sea fácil de comprender por los desarrolladores.

Esta charla es muy teórica en la que se explicarán estos dos proyectos, enseñando fuentes de información del material publicado (Servehappy) y de la parte de análisis de código PHP -y resto de código- (Project Tide); de aproximadamente 20 minutos.

November 16, 2017 — Do you have data and lists you keep having to massage to make it useful for your project? Have you heard of regular expressions but been frightened by the Klingon-looking examples? Fear no longer!

I’ll demystify regular expressions and show you how best to do them in PHP. We’ll cover the syntax and functions that make PHP a great text-parsing language, and give you the foundation to learn more.

As a bonus, I’ll give you two cases people often use as examples for regexes that PHP gives you better native ways to accomplish.

October 26, 2017 — Díky Bedrocku je možné používat WordPress přes Composer, což je nástroj na správu závislostí v PHP, který dle mého názoru ve WordPressu hodně chybí z programátorského hlediska.

October 23, 2017 — This talk will demonstrate the benefits of using Xdebug to debug PHP, why it beats the pants off of `var_dump()`, and how it has helped, and continues to help me become a better developer. I’ll talk a bit about what Xdebug is, how it works, and a few common scenarios where Xdebug has helped me to solve problems and gain a better understanding of how various tools work together. I’ll be running Xdebug on a Vagrant box and using PHP Storm for my demonstration. I will cover: 1. How to quickly configure a project to use Xdebug 2. How to set break points and step through code execution 3. How to inspect variables 4. How to use the console to evaluate expressions Xdebug isn’t hard to use, and once you’ve used it you’ll wonder how you ever lived without it.

October 23, 2017 — The talk discusses dependency injection to allow for Advanced PHP “containerization” of classes using autoloading, namespacing. We’ll look at this methodology used in other languages, but relatively new to PHP and how that can enhance WordPress development. We will discuss techniques used in the greater PHP community, while still embracing the philosophy, flexibility, and architecture of WordPress.

September 4, 2017 — Do you know what is available in PHP 7.1? Do you know how it changes how we build websites? If you are still a procedural and don’t plan on changing, skip this session. Otherwise, join us for a 20 minute whirlwind tour of the new tools in your toolbox.

August 5, 2017 — Just about any moderately complex WordPress plugin requires some sort of administrative interface. In many cases, your code for this UI could benefit from the flexibility and power provided by the React JavaScript library, but integrating React with the WordPress admin brings its own set of challenges. From developer tools, to data persistence, to extensibility, we’ll explore some of these challenges and the solutions we’ve developed at Modern Tribe as we’ve used React to build elegant administrative user experiences in WordPress.

Making React applications play nicely with the WordPress admin involves a number of tricks and workarounds. I’ll cover topics such as integration with the TinyMCE editor, communication with WP’s existing JS libraries, setting up developer tools such as hot module reloading, and persisting data in the WP database.

June 22, 2017 — Julka Grodel is a Senior Software Engineer at AddThis and has been working with CMSs for over 10 years.

Recently the recommended version of PHP for WordPress increased to PHP7, while still supporting PHP 5.2.4. That’s over 9 years of PHP! PHP7 is the first major release since PHP5 and includes backward incompatible changes that may change the way your code works or throw errors on your customer’s site where you’ve never seen them before. Let’s talk about important changes in variable handing, error handling, changed functions, removed functions and their alternatives, and more.
