You may of heard about the PHP-FIG group but aren't quite sure what they're about or what they've produced so far. In this new post on PHPBuilder.com, they get into some of the details of the group, including descriptions of the currently released PSRs.

If you have been watching the development of PHP over the last few years, you will know all about the problems with the language. The standard story is that PHP is a fragmented language, it is a language for hacks, there is no real specification, and so on and so forth. The reality is that PHP has grown up a lot recently. PHP 5.4 brings the language closer to a complete object model, and supplies a lot of new functionality. So far, so good. But what about frameworks? [...] PHP-FIG is the short name for the PHP Framework Interop Group (am I the only one who finds the naming of PHP groups and libraries after fruits amusing?) and their mission is simple: to find a way to get the PHP frameworks to work together.

They cover some of the members of the group (well, the projects represented) and look at each of the PSRs in detail:

• PSR-0 - Autoloading Standard
• PSR-1 - Basic Coding Standard
• PSR-2 - Coding Style Guide
• PSR-3 - Logger Interface
• PSR-4 - Improved Autoloading
