Functions in Recursive Word Counter:

1. wordCounter: returns the total words of a text.
2. uniqueWordCounter: returns the total of unique words of a text.

This is a class to study, however everything works!

Installation

You can add this library as a local, per-project dependency to your project using Composer:

composer require marcocianci/word-counter

If you only need this library during development, for instance to run your project's test suite, then you should add it as a development-time dependency:

composer require --dev marcocianci/word-counter

Usage

<?php
require __DIR__ . '/vendor/autoload.php'; // Autoload files using Composer autoload

use MarcoCianci\WordCounter;

$wordCounter = new WordCounter;
$text = 'Lorem ipsum dolor sit amet, consectetur adipiscing elit. Morbi cursus varius felis, 
ut hendrerit magna semper varius. Fusce sed consequat.';
$result = $wordCounter->wordCounter($text).PHP_EOL;
// $result == 20

print_r($wordCounter->uniqueWordCounter($text));
/*
