Training Materials:

    1. Websockets, ratchet, silex and redis pubsub implementation — A small, but interesting post about creating a real-time web service, which can be used via websockets. The author had a task to implement some backend for iOS app, and the obvious solution seemed to create a REST service, but this solution had some drawbacks. As a result, the author has implemented a simple tool for processing requests via websockets with Ratchet, Redis and Silex. Code and demo.
    2. PSR? — A good post with the review of all PSR standards. There was much of criticism against PSR, especially after PSR-3 release, however there are enough posts in its defense, such as this one, and especially this one.

  2. Node.js for PHP programmers2, 3, 4 — If you are a PHP developer, but you're thinking about getting engaged in something else, pay attention to Node.js. In a set of articles the author writes about the basic principles of development in Node.js and provides some examples of implementation of the same things in Node.js and PHP, which is especially useful.
  3. MongoDB's aggregation framework — In version 2.2 the aggregation framework, which provides powerful and flexible abilities to solve the problems of data aggregation, was presented in MongoDB. The post is an introduction to aggregation framework with examples in PHP.

  5. Getting Ahead In Security By Watching The Neighbours — The news about a critical vulnerability in Ruby On Rails (detailed analysis) discovered not so long ago, made the author to write this post. After some investigation, the author discovered a similar vulnerability in YAML parser in Symfony. Although the bug has been fixed, no one can ever be sufficiently warned, so the author asks to be vigilant and monitor the detected bugs carefully, not only in the tools you use, but also in their analogues.
  6. LUCID — A series of articles about the development on LUCID principles: L - Logging, U - Unit Testing, C - Configurability, I - Isolation, D - Documenting.
  7. Lithium: Getting Stuff From Your Database — A small article which describes work with database in the Lithium framework.
