Autoloading of PHP classes was introduced in Drupal 7. Through a mechanism known as "the registry", modules were able to specify the files that contained their class definitions, then simply use the classes without needing a require or include statement. This system definitely isn't perfect... Having a database backed registry caused a lot of queries for modules like Views that instantiate a lot of classes. It also required a cache clear to pick up any caches, and forced developers to maintain an explicit list of their classes, which then had to be parsed and scanned each time caches were cleared.

Meanwhile, in the broader PHP world, a system known as PSR-0 was conceived. PSR-0 is able to autoload classes with minimal explicit registration, and has no dependency on the database. Because it is a PHP standard (rather than a Drupal specific standard), you can also count on broad support for your favorite external libraries.

This article is a followup to Creating Tokens in Drupal 6. Part of the token module was moved into core for Drupal 7, meaning it is even easier to create and use tokens programatically. I'm going to walk through how to use tokens programatically in Drupal 7, both using existing tokens and creating new ones.

I recently made the switch from Hostgator Shared hosting to a Linode instance, and WOW. It's amazing what you can do with a single (relatively small) box dedicated to serving up a single site. Without any further ado, I want to share some tips I gathered from setting the server up, and some benchmark results from along the way.
