A PHP package to work with percentages

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.

Installation

You can install the package via composer:

composer require mattiasgeniar/php-percentages

Usage

// 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); // 2.4
