## What it is
PSL is a standard library for PHP inspired by Hack's HSL, providing consistent, well-typed APIs for collections, async, I/O, cryptography, validation, and terminal UI. It replaces PHP's inconsistent built-in functions with safer, async-ready alternatives that fail predictably.

## Use cases
- validate and coerce untrusted input with type combinators
- run concurrent tasks with structured concurrency in PHP
- work with collections using type-safe functional operations
- hash passwords and generate secure random values
- build terminal UIs with ANSI support
- handle multibyte strings and grapheme clusters correctly
- perform non-blocking TCP and network I/O

## When to choose
- you want a consistent, type-safe alternative to PHP's scattered built-in functions
- you need structured async concurrency in PHP without promise/callback complexity
- you're building PHP 8.4+ applications that benefit from strict typing and predictable errors

## When to avoid
- you must support PHP versions older than 8.4
- you're maintaining a legacy codebase deeply tied to native PHP functions
- you only need a tiny utility and don't want a full standard library dependency

## Facets
- artifact type: library
