Download the PHP package spatie/enum without Composer

PHP Enum

This package offers strongly typed enums in PHP. In this package, enums are always objects, never constant values on their own. This allows for proper static analysis and refactoring in IDEs.

Here's how enums are created with this package:

And this is how they are used:

Installation

You can install the package via composer:

Usage

This is how an enum can be defined.

This is how they are used:

Creating an enum from a value

When an enum value doesn't exist, you'll get a BadMethodCallException. If you would prefer not catching an exception, you can use:

When an enum value doesn't exist in this case, $status will be null.

The only time you want to construct an enum from a value is when unserializing them from eg. a database.

If you want to get the value of an enum to store it, you can do this:

Note that value is a read-only property, it cannot be changed.

Enum values

By default, the enum value is its method name. You can however override it, for example if you want to store enums as integers in a database, instead of using their method name.

An enum value doesn't have to be a string, as you can see in the example it can also be an int.

Note that you don't need to override all values. Rather, you only need to override the ones that you want to be different from the default.

If you have a logic that should be applied to all method names to get the value, like lowercase them, you can return a Closure.

Enum labels

Enums can be given a label, you can do this by overriding the labels method.

Note that you don't need to override all labels, the default label will be the enum's value.

If you have a logic that should be applied to all method names to get the label, like lowercase them, you can return a Closure as in the value example.

You can access an enum's label like so:

Note that label is a read-only property, it cannot be changed.

Comparing enums

Enums can be compared using the equals method:

You can pass several enums to the equals method, it will return true if the current enum equals one of the given values.

Phpunit Assertions

This package provides an abstract class Spatie\Enum\Phpunit\EnumAssertions with some basic/common assertions if you have to test enums.

Faker Provider

Possibly you are using faker and want to generate random enums. Because doing so with default faker is a lot of copy'n'paste we've got you covered with a faker provider Spatie\Enum\Faker\FakerEnumProvider.
