Temperature

Simple library to handle temperature scales. Features: * Display formatted tempteratue (e.g 100 °C) * Simple convert beetwen different scales, _(*2)

Supported temperature scales

• Celsius (C)
• Kelvin (K)
• Farenheit (F)
• Rankine (R)
• Reaumur (Re)

Install using Composer

require: {
    "ayeo/temperature": "~0.1"
}

Basic usage

use Temperature\Factory\DefaultFactory as TemperatureFactory;

$factory = new TemperatureFactory();
$temperature = $factory->build(63, 'F');

$temperature; //63 °F
$temperature->convert('C'); //17.2222222222 °C
$temperature->convert('C')->setPrecision(2); //17.22 °C

Auto conversion

You can set Factory to autoconvert temperatures to given scale, _(*3)

use Temperature\Factory\DefaultFactory as TemperatureFactory;

$factory = new TemperatureFactory;
$factory->setAutoconvertTo('C');
$factory->getFormatter()->setPrecision(2);

$factory->build(100, 'F'); //37.78 °C

Custom formatter

As default formatter is build by your locale settings. You can adjust it to your needs., _(*4)

use Temperature\Formatter\StandardFormatter;

$formatter = new StandardFormatter();
$formatter->setDecimalSeperator(",");
$formatter->setPrecision(2);
$formatter->setShowSymbolMode(false);

$factory->setFormatter($formatter);

$factory->build(10.50, 'C'); //10,50
$factory->build(100, 'K'); //100

You can write your own Formatter. I must implemetnts FormatterInterface., _(*5)

Custom temperature scale

Assume you need new temperature scale. For purpose of this example let say C2 = 2 * Celsius, _(*6)

use \Temperature\Scales\Scale\AbstractScale;

class C2Scale extends AbstractScale
{
    const SYMBOL = "C2";

    /**
     * @return float
     */
    function getValueInCelsius()
    {
        return $this->value / 2;
    }

    /**
     * @param $celsius
     */
    function setValueInCelsius($celsius)
    {
        $this->value = $celsius * 2;
    }
}

$factory->getSupportedScales()->addSupportedType('C2', 'C2Scale');
$factory->build(100, 'C')->convert('C2'); //200 C2
$factory->build(50, 'K')->convert('C2'); //-446 C2
