A handful of tools for PHP developers.

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

Installation
------------

[](#installation)

In case you want to try it out, run:

`php composer.phar require "h-util/belt:~2"`

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

Example
-------

[](#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]
```
