What’s Planned for PHP 6

Jeroen van der Meer has an article that takes a look at what’s coming in PHP 6.  Some of the more noteable features are improvements to the OO features of the popular web scripting language including the addition of namespaces.  Namespaces allows you to group variables, functions or objects under a certain name which lets the developer use the same name for a variable, function or object multiple times.  Other featues include improved caching and some changes to the extensions that are packaged with the base PHP install.
