Larry Garfield talks about a new feature of Drupal 7 in a new post to his blog - the new introspective code registry that's been introduced in this latest version.

As a GHOP Task , Cornil did a performance analysis of Drupal and found its two largest performance drains were the bootstrap process and the theming layer. Quite simply, Drupal spends too much time including code. [...] Fortunately, Drupal 7's self-learning code registry system has just landed, which should obliterate most of the wasted bootstrap cost.

Larry describes the "heart of it all", the token_get_all call, that parses through an entire PHP file, splitting out things like classes included and functions called. This is passed through a function_exists call to the current script and, if it's already there, the file isn't included repetitively.

A little while back, Alan Knowles wondered something that I'm sure has crosses the mind of every PHP developer out there, especially when they came across a particularly bad chunk of code - some people should need to apply for a license before releasing their PHP code out into the wild.

Unlike most of the reviews you get, I was specifically looking at code quality [of the CMSs]. not fuzzy does it look nice!

He looks at a whole list of them including: Tanslucis, Siteman, Pivot, jaf-cms, Guppy, Doop and CutePHP. Unfortunately, most of the news is bad - between badly structured code and mixes of HTML and PHP, there was almost nothing good in any of them.

The Developer Tutorials blog has posted this new guide on how to install one of the more popular PHP content management systems out there - Drupal.

One of the most popular CMSs is Drupal, partly because it offers all of the aforesaid features, and partly because developers familiar with PHP (the language used by Drupal) can modify the functioning and appearance of almost every aspect of Drupal.

In this tutorial, we will discuss how to install and configure a brand-new Drupal Web site from scratch. We will also touch upon the basics of adding content to a Drupal installation.

They include useful screenshots along the way as well, helping to guide you through the process a bit better than with just words. There's tons of configuration options that you could mess with in a Drupal installation, but they do well to give you the essential ones that you'll need to get it up and running smoothly.

The SitePoint PHP Blog has a new post from Matthew Magain spotlighting the release of the latest version of one of the more popular PHP CMS systems out there - Drupal 6.

The Drupal development team surprised everyone when they released version 6.0 last week, ahead of schedule.

Over sixteen-hundred issues were corrected and major changes (like usability improvements, security and an expanded development framework) were introduced. They've even created a screencast to help you set up your own CMS site even faster than before.

ProDevTips.com has posted part nine of their long-running series about using the Zend Framework (and Smarty) to create a CMS/Community website.

This piece covers creating a proper folder structure so that we can have a skin system. I've also created a folder for the admin section which is fully contained with it's own controllers folder and so on. Another unrelated change that has happened since the last part is sub menu logic which we will also take a look at.

They make updates to the bootstrap file to introduce another controller directory and, inside of that, create the Administrator controller and integrate it with a Smarty template to show different menu items if an admin user is logged in.

ProDevTips.com has posted the sixth part of their series using the Zend Framework to create a CMS/Community website with Smarty. This time they focus in on the gallery section of the site.

They go with a Flex/Javascript combination to make the uploads easier (see here) and include the database schema and GalleryController class to handle the uploads, make the thumbnails and display the user's current images (and thumbnails).
