Installation
Via Composer
$ composer require funct/funct
Usage
The library consist of five groups: Collection, Invoke, Object, Strings and General. Each group has it's own namespace suffix (Only General uses root namespace).
To include all group functions just include root namespace at the top of the file:
use Funct;
For single group functions you have two options. One is to include root namespace and call directly with full namespace for e.g.:
use Funct; Funct\Strings\classify('hello world');
or to include only single group for e.g.:
use Funct\Strings; Strings\classify('hello world');
If you are using PHP >=5.6 you can include only single function. For e.g.:
use function Funct\Strings\classify; classify('hello world');
General
