## What it is
A collection of Markdown reference documents summarizing the new features, changes, and backward compatibility breakages in PHP 7.0, 7.1, and 7.2. It acts as a consolidated quick-reference for PHP developers evaluating or performing upgrades across the PHP 7.x series.

## Use cases
- what's new in PHP 7
- PHP 7 backward compatibility breakages when upgrading from PHP 5
- PHP 7.1 new features overview
- PHP 7.2 changes and deprecations list
- migrate legacy PHP codebase to PHP 7
- learn PHP 7 scalar type declarations and return types
- PHP 7 upgrade guide with removed features

## When to choose
- You are upgrading a PHP 5 application to PHP 7 and need a summary of what will break
- You want a quick, organized overview of the syntax and features introduced in a specific PHP 7.x minor version
- You need a condensed changelog of language-level changes without reading the full RFCs

## When to avoid
- You need documentation for PHP 7.3 or later — coverage stops at PHP 7.2 (last updated 2018)
- You want the official, exhaustive PHP manual or complete RFC texts
- You prefer interactive tutorials or runnable example code over prose reference notes

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: documentation, markdown, developer-tools
- domain: programming-languages, documentation, developer-tools, tutorials
