Anthony Ferrara has a new article posted to his site today about parameter typecasting and the discussions that have been happening about it on the PHP "internals" mailing list.

As any of you who follow the PHP internals list know, scalar type hinting has been a hot topic as of late. You'll also know that I've submitted two new RFC (Request For Comment) proposals for inclusion of two new major features in the PHP language. I figured it was worth going into both RFCs and patches a little deeper, explain my rationale and (hopefully) garner some more visibility of the proposals.

He shares the details of the two main RFCs that are proposed right now - parameter type casting hints and object scalar casting magic methods (both with code examples). Right now, they're only in the patch stage and there's talk of improving the current casting functionality of PHP before something like one of these goes into place.

On the Symfony blog Fabien Potencier has a new post talking about a change in the support structure for developers wanting to get help with either Symfony1 or Symfony2 - a split in the mailing list to help make things a bit easier to split out.

Now that Symfony2 is just around the corner, we need to better organize community support for both symfony1 and Symfony2. As more people start using Symfony2, the user mailing-list is becoming more and more difficult to follow. [...] After an opinionated discussion on the mailing-list, I've decided to create two new mailing-lists that are replacing the current users mailing-list: one for symfony1 and another one for Symfony2. The current mailing-list has been switched to the archive mode; all messages will remain browseable and searchable but new messages will be rejected.

If you're a current member of the "users" mailing list and want a similar experience, you'll need to subscribe to both. Otherwise, pick the one you like and watch your inbox fill up. This break up makes it easier for people to find messages specifically related to their version of choice without having to look for the "[Symfony2]" tag in the subject line.

Freek Lijten has a recent post looking at some of the types of discussions that happen on the php-internals mailing list.

The internals list is the place to be to hear about the current state of PHP. It is one of PHP's many mailing lists, but this is the one where (core) developers discuss new features, current bugs and wild ideas. If you want to keep up with things it is a good idea to sign up, it is not an extremely high volume list and if you ignore the noise it is quite informative. In this article I would like to share examples of stuff typically discussed on the list.

He mentions feature requests in general and, more specifically things like traits support (multiple inheritance), array dereferencing, callable arrays and the debate over the short array syntax.

If you're a Campaign Monitor user (an email marketing tool targeted at designers) and have wanted to dynamically add people to your lists, Vidyut Luther has a solution for you:

This is a quick how to, for people interested in adding subscribers to their Campaign Monitor lists. What you'll need: PHP 5 with SOAP built in, a Valid Campaign Monitor Account, a Campaign Monitor list.

His simple script (about 10 lines with comments removed) makes a call to the service's API and passes in your key, a list and client ID and a call to the AddSubscriber method to push the new contact into the list.

As Lukas Smith mentions, the latest alpha release for the PHP 5.3 series has been released - PHP 5.3alpha2.

Wow, after what feels like ages PHP 5.3.0alpha3 was just released. Originally we hoped to be able to release now intermediate releases every 2-3 weeks, this one took a good 2 months. Somehow this releases did its very best to stall itself. People that needed to work on things together by chance ended up being busy with other things and vacations in just the right order to make things impossible. Most of this was to be attributed to the namespace discussions, which climaxed in the backslash FUD campaign.

He notes that a stable release is probably looking good in Q1 of 2009 (with namespaces being the delaying factor). He also suggests something that could help make things a bit simpler in the future - making the internals@ mailing list read-only for anyone outside of core developers. A good bit of the confusion and bickering came from those outside the dev team and it didn't help the group come to a decision any earlier.

You can find the official release information for the alpha2 on the main PHP.net website.

Ben Ramsey has a new blog post that mentions a move for the PHP User Group mailing list - putting it official on the php.net services.

You may recall PHP Groups being created over a year ago for the purpose of networking together the leaders and organizers of PHP user groups around the world. I've been very bad about keeping things moving on this front, but I want to pick things back up and get us talking again.

Lukas Smith has posted a quick emPHPower update to his blog today concerning recent thoughts and progress he's made on the initiative.

I hope this all will lead to a few people to step up and really start getting involved deeply in emPHPower. Aside from this Sebastian has handed in a BOF session on emPHPower for OSCON. I hope this one will work out.

A spot has also been set aside at the upcoming Zend/PHP Conference & Expo's unconference for someone to speak on the subject and to get a feel for things from the business perspective. Lukas has also been working up more details about the effort and has set up a mailing list to help with collaboration.

Eran Gelperin gives an overview of the current state of overloading abilities PHP has in a new blog post today:

Operator overloading is a programming language features that allows operators to act differently depending on the type of data they are operating on. Since OOP lets us create custom types (classes), there are plenty of opportunities to do useful and interesting code manipulations using operator overloading.

He talks about magic functions, the additions that the SPL made, the PECL addition operator and how much its currently being discussed on the PHP internals list.

In a new post to his blog, Pierre-Alain Joye has a suggestion for mailing list members (and really anyone else involved with the community) for reading materials - a chapter from "Producing Open Source Software".

A must read about OSS is the "Producing Open Source Software" written By Karl Fogel. One chapter covers nearly all problems that php Internals is experiencing.

No need to say that these rules should apply to IRC as well. You may think while reading the mailing lists that a certain level has been reached, what happens on IRC is even worst. Another chapter can be very interesting: Social and Political Infrastructure (and related). Mixing paid developers, volunteers or ambitious developers (as in need of an ego or career booster) is not an easy thing, but it should be possible (dreaming?).

Among the topics discussed in the chapter, Pierre mentions two - "nip rudeness in the bud" to keep things more civil and from escalating and to avoid private discussions about a project that everyone should be involved with.

Lukas Smith has two updates on the previously mentioned database mailing list - both about how you can access the list:

• After all this positive feedback I have asked Ian P. Christian, who is already hosting the doctrine mailing lists, to open up a mailing list for us: mailto:phpdbabstraction+subscribe@lists.pengus.net
• This list is now also accessible via Gmane(.org): http://dir.gmane.org/gmane.comp.php.dbabstraction nntp://news:gmane.comp.php.dbabstraction

If you're a maintainer of a database abstraction package or just wnt to get into talk more than the usual tech support, be sure to check th mailing list out.
