In the wake of the success of the PSR-0 standard (used in autoloading structures across frameworks and various applications), the PHP-FIG (Framework Interoperability Group) has start on drafts of other standards to help provide some guidelines to standardize PHP development across projects.

Among the group, Paul Jones has been writing serveral proposals under the PSR-1 standard banner that include:

• The basic draft of the standard
• An extended draft of the same
• A more advanced version, PSR-2 that also includes some survey results on various syntax elements.

If you want to know more about the PHP-FIG group, you should listen to this excellent panel interview of the group from the Voices of the ElePHPant podcast. Paul and others get into the point of the group and how the standards are progressing.
