README
This library provides helpers for several enum operations:
- compare
- to array
It also provides an abstract EnumTestCase
.
Installation
composer require oskarstark/enum-helper
Usage
For example, you have the following Enum:
<?php declare(strict_types=1); namespace App\Enum; enum Color: string { case RED = 'red'; case BLUE = 'blue'; }
You can use the following trait,
<?php declare(strict_types=1); namespace App\Enum; +use OskarStark\Enum\Trait\Comparable; +use OskarStark\Enum\Trait\ToArray; enum Color: string { + use Comparable; + use ToArray; case RED = 'red'; case BLUE = 'blue'; }
Comparable
Trait
This trait
gives you the possibility to compare you enum
with another one or a collection of enums like the
following:
App\Enum\Color::RED->equals(App\Enum\Color::BLUE); // returns false
App\Enum\Color::RED->notEquals(App\Enum\Color::RED); // returns false
App\Enum\Color::RED->equalsOneOf([ App\Enum\Color::BLUE, App\Enum\Color::RED, ]); // returns true
For example, you want to check if a color is a nice color:
<?php declare(strict_types=1); namespace App\Enum; use OskarStark\Enum\Trait\Comparable; use OskarStark\Enum\Trait\ToArray; enum Color: string { use Comparable; use ToArray; case RED = 'red'; case BLUE = 'blue'; case GREEN = 'green'; public function isNice(): bool { return self::equalsOneOf([ self::BLUE, self::GREEN ]); } }
App\Enum\Color::RED->isNice(); // returns false App\Enum\Color::BLUE->isNice(); // returns true
ToArray
Trait
This trait
gives you the possibility to get an enum as array like the following:
For Backed Enum
App\Enum\Color::toArray(); // returns ['RED' => 'red', 'BLUE' => 'blue']
For Non-Backed Enum
App\Enum\NonBackedEnum::toArray(); // returns ['RED' => 'RED', 'BLUE' => 'BLUE']
