Everyone knows the php.net site. All of us went there sooner or later,
and will keep going back there. This is the central reference point for PHP
users, and there is a wealth of information there. Not all of it is obvious.
Come with me, I'll show you.
This is the primary web site. The front page is where major news is published: new PHP versions, security updates, and new projects launched. This site is also mirrored in dozens of countries worldwide.
This is the home of the download page, for everyone to get the latest version of the PHP source code and binaries for Windows. The current and next-to-current versions are available there. (There is also a PHP Museum, which has all of the source distributions since June 1996.)
The next most visited section is the documentation. The documentation is translated into twelve different languages, and is available in a variety of different formats. Users are able to read notes on the documentation left by other users, and contribute their own notes. The documentation is a real community project by itself!
The support page has all the directions to a wealth of resources both inside and outside of PHP.net. The community has built a huge network of knowledge bases, PHP user groups, and training sessions where anyone can have his or her questions answered. Non-English-speaking users also get a large share of attention.
Now, buckle up your seat belt, and stop smoking. Here are the no-light streets:
This is where speakers at various PHP-related conferences keep their slides. It covers all sorts of topics, from the famous 'Rasmus' introduction to PHP to the latest 'PHP system administration', through PEAR and advanced topics. All those slides are available within the PHP slide application.
news.php.net is the web interface to the PHP mailing lists. If you're not subscribed to the mailing lists, but you still want to keep in touch regularly, this is your place. An infinite pile of fresh news and trends of PHP. You can also point your news reader at the NNTP server at news.php.net to follow the lists.
PEAR is the next revolution in PHP. This repository is bringing higher level programming to PHP. PEAR is a framework and distribution system for reusable PHP components. It eases installation by bringing an automated wizard, and packing the strength and experience of PHP users into a nicely organised OOP library.
PECL is a repository for PHP Extensions, providing a directory of all known
extensions and hosting facilities for downloading and development of PHP
extensions.
The packaging and distribution system used by PECL is shared with
its sister, PEAR.
The bug database is where you can bring problems with PHP to the attention of developers (but don't forget to double-check that somebody else hasn't already reported the same problem!).
This page provides set of useful tools for PHP Manual translators and contributors.
The Quality Assurance team is one of the most important pieces of the PHP project, protecting users from bugs. It is gathered around the QA mailing list, and this site allows anyone to provide tests and experience to the release process.
The PHP project is organized with a Git server, and this website is the web interface to it. There you can browse the history (and latest versions) of the source code for all of the PHP projects. For example, the php-src module is the repository for the source code to the latest version of PHP itself. Checking out the source code can be done anonymously.
Using OpenGrok is another option to view the source code, and it offers additional features like search and cross referencing.
Home of the official PHP wiki, this site contains information related to php.net like RFCs, GSOC information, and TODO files. Most every aspect of the PHP project has a wiki section and everyone is able to apply for wiki commit access.
This site is dedicated to supporting PHP on Microsoft Windows. It also supports ports of PHP extensions or features as well as providing special builds for the various Windows architectures.
