In last month’s column of PSR Pickup, I talked about PSR-4 Autoloader (PSR-0 was the first Autoloader PSR) and PSR-1 Basic Coding Standard. In this month’s column, I’ll be talking about PSR-12 Extended Coding Style Standard. PSR-12 builds on PSR-1 and is significant in the number of rules it defines, most of which are formatting styles well-supported by modern IDEs.
