Temperature Value Objects

This repository provides Temperature ValueObject implementation for PHP that is easy to use and easily allow your classes to depend on Temperature object instead of just float or string.

Install

You can install this package via composer

composer require php-value-object/temperature

Example

function isItWarm(Temperature $temperature) : bool
{
    $hot = new Celsius(23);
    if($temperature->gte($hot)) {
      return true; // t-shirt time
    }
    
    return false; // jacket time
}

$temperature = new Kelvin(0);
isItWarm($temperature); // false

Usage

The temperature classes are supported: Celsius, Fahrenheit and Kelvin.

It is possible to compare them via helper methods:

• eq - equals
• gt - greater than
• gte - greater than or equals
• lt - less than
• lte - less than or equals
• compareTo - returns -1, 0, 1 if less than, equal or greater than

To introduce new temperature class simply extend Temperature.
