The XML content of phpdoc files is updated from day to day, and on busy days from hour to hour. To follow the updates in the English tree and any other language's tree and also participate in the discussions, it is highly recommended that you subscribe to the <phpdoc@lists.php.net> mailing list. You can subscribe by sending a blank mail to phpdoc-subscribe@lists.php.net. Similarly you can unsubscribe by sending a blank mail to phpdoc-unsubscribe@lists.php.net. There is a web interface for these tasks at http://www.php.net/mailing-lists.php.
Currently this list receives messages from the following senders:
Members of the list: discussion threads about anything related to the phpdoc team.
The CVS server: diffs about every small modification in the English or any languages XML files, or other support files placed in the phpdoc repository.
The PHP bug tracking system: bug follow ups classified as "Documentation Problem" in the bug system.
Other senders: the posting to list is not restricted, so people not on the list can also post messages. This way we got bug reports and suggestions by plain mails on the list.
SPAM: this is not a common piece of mail, thanks to our SPAM protection system.
If you can't handle the load of this mailing list in your mailbox, you can read the messages three ways:
On the web, in the archives at http://marc.theaimsgroup.com/?l=phpdoc
With a news reader at news://news.php.net/php.doc
On the web, with the experimental news interface at http://news.php.net/group.php?group=php.doc
You can also set up some filter on incoming mail messages, so you get the most important things, and can participate in the discussions while do not need to read big diff messages. To ease the filtering the commit messages coming from the CVS server, that are larger then 8kb, are put into attachements. You can always see the commit message and file list in the body, but the diff is in an attachement.
As the Windows HTMLHelp Edition of the manual is evolving in an incredible way, there is a separate mailing list for CHM related discussions and announcements. You can subscribe to this mailing list at http://www.php.net/mailing-lists.php using the web interface.
There is also a mailing list named php-notes. You can access it the same way as the phpdoc list (just substitute phpdoc with php-notes). This list is the place where all the manual notes are posted. You may consider subscribing to this mailing list if you would like to help manage the notes.
