## What it is
The official repository of PHP Standard Recommendations (PSRs) maintained by the PHP Framework Interop Group (PHP-FIG). It hosts proposed and approved interoperability standards covering autoloading, interfaces, HTTP messaging, and coding styles for PHP projects.

## Use cases
- find the current PSR standards for PHP interoperability
- learn PSR-4 autoloading conventions
- read PSR-7 HTTP message interface specifications
- propose a new PHP Standard Recommendation
- check the PER coding style guidelines
- understand PSR-3 logging and PSR-11 container interfaces

## When to choose
- you need the authoritative text of PHP interoperability standards
- you want to make a PHP library or framework compliant with PSRs
- you are drafting or reviewing a proposed PSR

## When to avoid
- you need runnable code or reference implementations rather than specification documents
- you want official translations of the standards
- you need help debugging PHP application code

## Facets
- artifact type: learning-resource
- maturity: active
- function: documentation, developer-tools
- domain: developer-tools, web-development, programming-languages, documentation
- platform: php
