## What it is
APCu is a PHP extension providing an in-memory key-value store for caching PHP variables within a single process. It is the userland-only portion of the legacy APC opcode cache, exposed through apcu_* functions documented on php.net.

## Use cases
- cache expensive function results in php
- shared memory key-value store for php requests
- speed up php application by caching variables
- replace apc user cache in modern php
- store computed data between requests without external cache

## When to choose
- you need fast per-server variable caching in php without adding external services
- you want a drop-in userland cache maintained as part of the php ecosystem

## When to avoid
- you need a distributed cache shared across multiple servers
- you need opcode caching (use opcache instead)
- your application runs in an environment without shared-memory php extensions

## Facets
- artifact type: library
- maturity: stable
- function: caching, database
- domain: web-development, backend, performance
- platform: php, windows
- tags: php-extension, in-memory-cache, key-value-store, shared-memory, pecl, linux, macos, web-server
