fphp

A set of auto-curried immutable data-last functions for PHP. Inspired by lodash/fp.

Requires php >= 7.0

Why use this ?

• Functions are curried and take data as their last argument so you can easily compose them.
• Enables you to do point-free programming.
• All functions are immutable and have similar interfaces: iteratee-first, data-last with the rest of the parameters in between.

How to install

composer require kilbiller/fphp

Pro tips

• Functions with an arity of one are also curried so you can avoid using a callable to compose them:

  flow(flatten())([1, [2, 3]]) ==> [1, 2, 3]

Tests

To run the tests simply do composer run test. You can also check code coverage by running composer run test:coverage.
