In 2009 the PHP-FIG created PSR-0: an autoloading standard that helped to change the landscape of PHP forever, thanks in no small part to its integration with Composer. Well, PSR-0 was built in a land before PHP had namespaces, when Horde and PEAR were prevalent and Composer was but a twinkle in the eye of two developers. In December 2013 PSR-4 was released as a newer, shinier version of that standard.
The FIG has more standards happening, some of which may be out just in time for this talk.
