Prefixes serve their primary purpose well: when used correctly, they will ensure that your class names do not have naming conflicts. Unfortunately, they are long and pedantic, and provide no additional benefits. [...] Namespaces provide other benefits than shorter class names, though.

He illustrates with a well-structured example that makes it clear as to what resources are being used and how they're split out. His snippet defines the structure of the rest of the script without even a line of code in the class. He also briefly mentions the PHP 5.3 adoption levels and notes that several larger projects will be 5.3-only soon and will start to force the hand of developers and hosting companies.

DI is fairly simple - its main goal is the removal of a class dependency from some code. This class dependency is then 'injected' into the code where it is needed. Using dependency injection helps in code maintenance, re-usability, testability, and improves code readability.

A code example is included of a User class that is responsible for making "users" and including all of the needed information and functionality to go with it in a self-contained object. They also mention some of the benefits that come along with it and the complications that could come from its use.

One of the most painful steps in any web system is importing content - especially so with Drupal. It is something that I have always dreaded. [...] That is all in the past. I am happy now. I recently discovered a module that is a crown jewel in the Drupal Contrib community - Feeds.

With the Feeds module you can directly pull the information in from the feeds your site already provides (or ones you could whip up quickly) and pull it directly into your new site - even CSV content will work.

I am really enjoying my new smartphone. However there is still something missing. A way to have all my passwords with me on my phone in a safely encrypted container.

The Revelation system pushes the passwords into subversion when they're updated and can be accessed from a desktop platform. He was missing the mobile branch of the access, so he decided to fill the gap with PHP by making a reverse transformer for the Revelation passwords. You can get the code here from github if you want to make use of it on your own systems.

This screencast should help you setup Zend_Tool in your Zend Framework application. Zend_Tool is a command line entry point into your application. [...] The goal of this video is to start looking at how we can generate our own Manifest and Provider classes so that custom command line tools can be integrated into the Zend Framework application.

You can watch the screencast on the in-page player and can get a copy of the code from the project's repository.
