(Their other design pattern articles include ones on command and factory patterns).In this article I'll show you how to implement the Observer Pattern. You'll learn how various classes in the pattern relate to one another as subject and observers, how the subject notifies observers of a change in its state, and how to identify scenarios where it would be...
Cal Evans has posted a great tongue-in-cheek post to his blog today giving reasons why you shouldn't hire PHP community members to work at your company.It is no secret that I spend a lot of time promoting the PHP Community. It is a vibrant, helpful and friendly community and I've said before that I believe it to be one of the most important asserts of the PHP language. I'm also a realist though; I've built teams and I've hired developers. [...] I have experience in this area and I have strong opinions. I...
In a quick new post to his blog, Rob Allen shows how you can override a module's configuration in a Zend Framework 2 application. In his example, he uses the "User" module and overrides two of the "magic paths" it creates.Let's say that you install the ZF-Common's User module. By default, it sets up its routes under the /user path segment. [...] This config section will create the routes /user and through the magic of child_routes, also create /user/login and other required routes. If you don't want...
In this new post to his blog Chris Hartjes offers up a few of his own thoughts about testing APIs and some of the issues/concerns he's come across in his own testing (via Behat).I have been asked a few times on Twitter for some advice on how to use testing tools in order to test APIs. It just so happens that I am writing a bunch of tests for an API at work so perhaps this is a very timely blog post. [...] When you are testing an API you main concern is your ability to reproduce the results of a specific...

In this quick post to his blog Mattias Geniar looks at three different Apache flags you can use in your configuration/.htaccess files to set various things in your PHP environment.Back in 2009 there was a bug in the php_admin_value implementation before PHP 5.2.6. Since then, everything should run smoothly again. However, I find there's still a lot of confusion on when to use php_value, php_admin_value, php_flag and php_admin_flag. So I'll see if we can clear some of that.He compares the three php_*...
On the NetTuts.com site today there's a quick tutorial comparing two of the main database access methods available to PHP developers - PDO and MySQLi - based on performance and features they each have.When accessing a database in PHP, we have two choices: MySQLi and PDO. So what should you know before choosing one? The differences, database support, stability, and performance concerns will be outlined in this article.The article starts with a summary of what each of the tools offers as far as features,...

Dave Marshall is in the process of building a "RESTish" web service and has shared some of his planning steps in a new post to his blog.This post is going to describe how I've ending up designing, what I consider to be a fairly RESTful web API. I'm far from being an expert, and this is definitely the closest thing to a RESTful API that I've ever created, so I'm not even experienced with REST APIs. [...] Until about 6 months ago, I'd always been sceptical of creating RESTful APIs, but I think I've had a...

Well, I've been a little lazy around here and haven't posted since the beginning of the year. I figured I'd fix that by posting an update about a few things going on around here.
First off, since the schedule was just released, I'll mention that I'll be presenting at this year's Dutch PHP Conference with three different sessions (well, kind of just two):
Simple Session (PDO / MySQL)
DB Schema Management
PDO Database Connection
Smooth Scroll CakePHP Plugin
User Agent Parser
Seth Davis has put together a github repository with some benchmarking for some of the most common web frameworks - both PHP and not. His statistic is "requests per second" in a few scenarios: a "hello world" string test, a test with a database connection and one with a templated response.It should also be noted that my goal here was not necessarily to figure out how fast each framework could perform at its most optimized configuration (although built-in caching and other performance tweaks were usually...
Marcelo Gornstein has posted a new article showing how to use SWIG and libpcap to sniff packets from the network directly from his PHP application.I've been wanting to try SWIG for a long time, but never got the chance, for one thing or the other. So this weekend I've finally decided to give it a try by trying to create a php extension that access a small C++ wrapper for libpcap, so I can sniff packets directly from PHP. Just for fun (and actually because I couldn't find any active pecl extension to use...

On the Voices of the ElePHPant podcast today Cal Evans has posted the latest interview with a member of the PHP community. This time it's Matthew Weier O'Phinney, lead on the Zend Framework project.Cal's "three questions" for Matthew were:
Since Zend Framework is the opposite of the ideals behind the Micro PHP Manifesto, what are your thoughts on it?
Zend Framework 2 is close but not done - should a new project go with v1 or v2?
What's your local user group and it's URL (hint: there's not one yet)

Changes to the "dev" version handling
Major bugfixing in the...

In his latest post Rob Allen seeks to answer the question "what problem does dependency injection solve?":Zend Framework 2 comes with a dependency injection container (DIC), as does Symfony 2 and Aura, along with many other PHP frameworks that target PHP 5.3 or hight nowadays. This article attempts to explore the problem that a DIC tries to solve.He gives an example (somewhat based on the same structure of his Zend Framework tutorial) showing how you could use DI to inject the Artist object into the...
