DEPRECATION NOTICE: this package has been moved and improved at grizz-it/enum
Ulrack Enum is an implementation of enumerable objects for PHP. It uses two interpreter hooks to allow type-hinting and simply retrieving the value.
To install the package run the following command:
composer require ulrack/enum
In order to create an enumerable, create a new class which extends Ulrack\Enum\Enum.
Then add all the options as constants in the newly created class.
Optionally it is possible to define the callable methods in a doc-block above the class definition.
An implementation of the enumerable would look like the following:
<?php
/**
* Copyright (C) GrizzIT, Inc. All rights reserved.
* See LICENSE for license details.
*/
namespace MyProject\MyPackage\Common;
use Ulrack\Enum\Enum;
/**
* @method static EnumMock FOO()
* @method static EnumMock BAR()
*/
class MyEnum extends Enum
{
const FOO = 'foo';
const BAR = 'bar';
}The desired enumerable value can then be retrieved by calling MyProject\MyPackage\Common\MyEnum::FOO().
This will retrieve an instance of MyProject\MyPackage\Common\MyEnum with a set value of foo.
The value foo can be retrieved by casting the object to a string.
An implementation of this in action would look like the following:
<?php
/**
* Copyright (C) GrizzIT, Inc. All rights reserved.
* See LICENSE for license details.
*/
namespace MyProject\MyPackage\Namespace;
use MyProject\MyPackage\Common\MyEnum;
class MyImplementation
{
/**
* Constructor
*
* @param MyEnum $option
*/
public function __construct(MyEnum $option)
{
$this->option = (string) $option;
}
}
new MyImplementation(MyEnum::FOO());The MyProject\MyPackage\Common\MyEnum class also inherits some functionality from the Ulrack\Enum\Enum class.
For example to retrieve all options, the static method getOptions can be called on MyEnum.
This would retrieve an associative array of the options.
It is also possible to retrieve the enumerable name by supplying the value to a different function.
This can be done by calling MyEnum::getOrdinal('foo') which would yield FOO.
