README

This class was created because of this Stack Overflow question: https://stackoverflow.com/questions/254514/php-and-enumerations

Many times I was googling for Brian Cline's answer. And as many times I copied it, that many times I was extending it for my needs.

But not again.

I have rewritten and extended the class, and the result is this package!

Installation

composer require zrnik/enum

Change Log

1.0.0 - Re-Namespace Release (from zrny/enum)

Usage

Create Enum Class

use Zrnik\Base\Enum;
class DayOfWeek extends Enum
{
    const Sunday = 0;
    const Monday = 1;
    const Tuesday = 2;
    const Wednesday = 3;
    const Thursday = 4;
    const Friday = 5;
    const Saturday = 6;

}

Compare

if($this->Stardate->DayOfWeek === DayOfWeek::Monday)
{
    $this->spaceTime = new SpaceTime();
     //TODO: Decide if light will be particle or wave
    $this->spaceTime->addComponent(new Light());
}

Enumerate

foreach(DayOfWeek::getValues() as $value)
{
    echo 'It\'s '.DayOfWeek::getName($value).' and im still lazy. '.PHP_EOL;
}

foreach(DayOfWeek::getNames() as $name)
{
    echo 'It\'s '.$name.' and im'.(DayOfWeek::getValue($name) === DayOfWeek::Monday ? ' ':' still ').'lazy. '.PHP_EOL;
}

Check

if(DayOfWeek::getValue("Monday") === DayOfWeek::Monday) {
    // true
}

if(DayOfWeek::getValue("monday") === DayOfWeek::Monday) {
     // Invalid Argument Exception
}

if(DayOfWeek::getValue("monday", false) === DayOfWeek::Monday) {
    // true, case sensitivity disabled
}

if(DayOfWeek::getValue("monday ", false) === DayOfWeek::Monday) {
    // true, not case sensitive AND it gets trimmed automatically
}

???

PROFIT!
