PHP-FIG is a committee of members hailing from a broad splash of frameworks. There has been very little leadership in the PHP community regarding coding standards (all frameworks have their own "coding guidelines" for contributing to core/building packages) so this group establishes standards for that. They have branched out and there are efforts towards establishing common interfaces too (logger, http client, and so forth). PSR-1 and PSR-2 are generally accepted as being authoritative on how to write "Good PHP".
