In a new post on the IBM developerWorks page, Nathan Good takes a look at some of the features of the up and coming versions of the PHP language including things like namespaces, changes in the XML handling and a few things taken out.

PHP's next edition, V6, includes new features and syntax improvements that will make it easier to use from an object-oriented standpoint. Other important features, such as Unicode support in many of the core functions, mean that PHP V6 is positioned for better international support and robustness.

New features he mentions include namespace support, improvements to the native Unicode support as well as a few of the things that will be permanently retired like the php.ini settings for magic_quotes and register_globals.

The main PHP.net website has posted a list of people participating in this year's Google Summer of Code project on various PHP projects. These include:

• PHP Optimizer by Samuel Graham Kelly IV, mentored by Derick Rethans
• gsoc:2008 - XDebug by Chung-Yang Lee, mentored by David Coallier
• PHP Bindings for Cairo by Akshat Gupta, mentored by Anant Narayanan
• Implement Unicode into PHP 6 by Henrique do Nascimento Angelo, mentored by Scott MacVicar

You can check out more information on the projects (including links to their individual pages) on this page of the Google Code website.

On the Make Me Pulse blog, there's a look at PHP6's support of Unicode in the SPL (Standard PHP Library) TextIterator handler.

I've just install the last version of PHP6 dev and I've decided to test the famous new feature, the PHP Unicode Support. I will not explain new things about PHP6 or Unicode or TextIterator, it's just my discoveries test on this features.

He steps through the process he followed - enabling Unicode support, testing various output methods (including just an echo and using the TextIterator) as well as some of the manipulation methods (next/first/current) that can be used to get certain characters out of a string.

Sara Golemon, being interested in Unicode as she is, decided to investigate further when she saw a recent post about issues with Unicode math symbols:

Being a whimsical sort, I decided that actually implementing his request would be more fun than simply pish-poshing it. I'm not suggesting this be part of PHP6 (I still don't personally think it's a good idea), but it's a fun exercise and good for a conversation starter...

There's several things she can now do with the special characters including dumping out the results of divisions, comparisons and fractions natively.
