Stands for PHP Standards Recommendation. It provides a coding standard for PHP and simplifies the coding process. Currently there are several accepted PSRs (PSR-1, 2, 3, 4, 6, 7, 11, 13, 16) that describe basic coding and style, as well as standardize logger, HTTP message and caching interfaces, and others.

A number of PSRs, including documentation standards, are in status of a draft and haven’t been accepted yet.
