Simple library to handle temperature scales. Features:
- Display formatted tempteratue (e.g 100 °C)
- Simple convert beetwen different scales
- Celsius (C)
- Kelvin (K)
- Farenheit (F)
- Rankine (R)
- Reaumur (Re)
require: {
"ayeo/temperature": "~0.1"
}
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 °CYou can set Factory to autoconvert temperatures to given scale
use Temperature\Factory\DefaultFactory as TemperatureFactory;
$factory = new TemperatureFactory;
$factory->setAutoconvertTo('C');
$factory->getFormatter()->setPrecision(2);
$factory->build(100, 'F'); //37.78 °C
As default formatter is build by your locale settings. You can adjust it to your needs.
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'); //100You can write your own Formatter. I must implemetnts FormatterInterface.
Assume you need new temperature scale. For purpose of this example let say C2 = 2 * Celsius
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 C2The MIT License (MIT). Please see the license file for more information.
