Belt

A handful of tools for PHP developers.

Version 2.0.0 is out now. Clear documentation, improved tests and code quality.

Installation

In case you want to try it out, run:

php composer.phar require "ilya/belt:~2"

That will add Belt to your project as a Composer dependency.

Example

A little taste of Belt:

use Belt\Belt;

Belt::max([1, 2, 3]) // => 3

Belt::flatten([1, [2, [3]]]) // => [1, 2, 3]

Belt::last([1, 2, 3], 2) // => [2, 3]
