A clean interface to calculate percentages in PHP: changes between values, percentage increases, partial values, extensions, ...
Think of it as a very lightweight math library for the basic stuff. Aimed to make your code more readable and easier to understand.
You can install the package via composer:
composer require mattiasgeniar/php-percentages<?php
use Mattiasgeniar\Percentage\Percentage;
// What's the percentage increase from 100 to 120?
Percentage::differenceBetween(100, 120); // 20%
// What's the absolute percentage change from 100 to 80?
// (uses the abs() function)
Percentage::absoluteDifferenceBetween(100, 80); // 20%, not -20%
// How much is 120 compared to 100?
Percentage::calculate(120, 100); // 120%
// How much is 50 compared to 100?
Percentage::calculate(50, 100); // 50%
// What is 20% of 200?
Percentage::of(20, 200); // 40
// What is the 140% extension from 3 to 2?
Percentage::extension(140, 3, 2); // 1.6
// What is the 140% extension from 1 to 2?
Percentage::extension(140, 1, 2); // 2.4composer testPlease see CHANGELOG for more information on what has changed recently.
