## What it is
Underscore.php is a PHP port of the popular Underscore.js utility library, providing functional-style collection, array, and object manipulation helpers. It supports both static and object-oriented call styles and includes unit tests matching the original JavaScript library.

## Use cases
- manipulate arrays and collections in PHP with functional helpers
- use map, reduce, and filter utilities in PHP
- port JavaScript Underscore.js code to PHP
- chain collection transformations in object-oriented style
- work with arrays and objects using a consistent utility API

## When to choose
- you want Underscore.js-style utilities in a PHP project
- you prefer functional collection manipulation over verbose PHP loops
- you need a small, MIT-licensed utility library with matching tests

## When to avoid
- you are starting a modern PHP project where native array functions or newer libraries fit better
- you need actively developed features or recent PHP version support
- you want lodash-style performance optimizations
