PHP Enum Enhancements

A Composer package for PHP that adds some helpful enum traits to the glorious new PHP Enum type.

The package so far provides;

• A handy trait that extends PHP's native Enum type
• Adds a new static UnitEnum::valueArray(): array method that returns all values within an Enum as an equally typed array of Enum values
• Adds a new static UnitEnum::valueList(string $separator = ', '): string method that returns all values within an Enum as a comma separated list string

The package is available on Packagist as othyn/php-enum-enhancements.

Installation

Hop into your project that you wish to install it in and run the following Composer command to grab the latest version:

composer require othyn/php-enum-enhancements

Usage

For more comprehensive usage examples, you can view the test suite. However I'll show some basic usage examples below.

Enum: Value Array

<?php

namespace App\Enums;

use Othyn\PhpEnumEnhancements\Traits\EnumEnhancements;

enum TestEnum
{
    use EnumEnhancements;

    case Alpha;
    case Bravo;
    case Charlie;
    case Delta;
    case Echo;
}

var_dump(TestEnum::valueArray());

// Results in the following being printed:
// array(5) {
//   [0]=>
//   string(5) "Alpha"
//   [1]=>
//   string(5) "Bravo"
//   [2]=>
//   string(7) "Charlie"
//   [3]=>
//   string(5) "Delta"
//   [4]=>
//   string(4) "Echo"
// }

Enum: Value List

<?php

namespace App\Enums;

use Othyn\PhpEnumEnhancements\Traits\EnumEnhancements;

enum TestEnum
{
    use EnumEnhancements;

    case Alpha;
    case Bravo;
    case Charlie;
    case Delta;
    case Echo;
}

var_dump(TestEnum::valueList());

// Results in the following being printed:
// string(34) "Alpha, Bravo, Charlie, Delta, Echo"

var_dump(TestEnum::valueList(separator: ':'));

// Results in the following being printed:
// string(30) "Alpha:Bravo:Charlie:Delta:Echo"

Backed String Enum: Value Array

<?php

namespace App\Enums;

use Othyn\PhpEnumEnhancements\Traits\EnumEnhancements;

enum TestStringBackedEnum: string
{
    use EnumEnhancements;

    case Alpha   = 'alpha';
    case Bravo   = 'bravo';
    case Charlie = 'charlie';
    case Delta   = 'delta';
    case Echo    = 'echo';
}

var_dump(TestStringBackedEnum::valueArray());

// Results in the following being printed:
// array(5) {
//   [0]=>
//   string(5) "alpha"
//   [1]=>
//   string(5) "bravo"
//   [2]=>
//   string(7) "charlie"
//   [3]=>
//   string(5) "delta"
//   [4]=>
//   string(4) "echo"
// }

Backed String Enum: Value List

<?php

namespace App\Enums;

use Othyn\PhpEnumEnhancements\Traits\EnumEnhancements;

enum TestStringBackedEnum: string
{
    use EnumEnhancements;

    case Alpha   = 'alpha';
    case Bravo   = 'bravo';
    case Charlie = 'charlie';
    case Delta   = 'delta';
    case Echo    = 'echo';
}

var_dump(TestStringBackedEnum::valueList());

// Results in the following being printed:
// string(34) "alpha, bravo, charlie, delta, echo"

var_dump(TestStringBackedEnum::valueList(separator: ':'));

// Results in the following being printed:
// string(30) "alpha:bravo:charlie:delta:echo"

Backed Int Enum: Value Array

<?php

namespace App\Enums;

use Othyn\PhpEnumEnhancements\Traits\EnumEnhancements;

enum TestIntBackedEnum: int
{
    use EnumEnhancements;

    case One   = 1;
    case Two   = 2;
    case Three = 3;
    case Four  = 4;
    case Five  = 5;
}

var_dump(TestIntBackedEnum::valueArray());

// Results in the following being printed:
// array(5) {
//   [0]=>
//   int(1)
//   [1]=>
//   int(2)
//   [2]=>
//   int(3)
//   [3]=>
//   int(4)
//   [4]=>
//   int(5)
// }

Backed Int Enum: Value List

<?php

namespace App\Enums;

use Othyn\PhpEnumEnhancements\Traits\EnumEnhancements;

enum TestIntBackedEnum: int
{
    use EnumEnhancements;

    case One   = 1;
    case Two   = 2;
    case Three = 3;
    case Four  = 4;
    case Five  = 5;
}

var_dump(TestIntBackedEnum::valueList());

// Results in the following being printed:
// string(13) "1, 2, 3, 4, 5"

var_dump(TestIntBackedEnum::valueList(separator: ':'));

// Results in the following being printed:
// string(9) "1:2:3:4:5"

Development

Most development processes are wrapped up in an easy to use Docker container.

Enforcing Style

The projects .php-cs-fixer.dist.php config contains the rules that this repo conforms to and will run against the ./src and ./tests directory.

For remote style enforcement there is a GitHub Action configured to automatically run phpcsfixer.

For local style enforcement there is a composer script composer style configured to run phpcsfixer.

Testing

For remote testing there is a GitHub Action setup to automatically run the test suite on the main branch or and PR branches.

For local testing there is a Docker container that is pre-built that contains an Alpine CLI release of PHP + PHPUnit + xdebug. This is setup to test the project and can be setup via the following:

composer docker-build

This should trigger Docker Compose to build the image. You can then up the container via the following:

composer docker-up

There are tests for all code written, in which can be run via:

# PHPUnit with code coverage report
composer test

# PHPUnit with code coverage report, using local phpunit and xdebug
composer test-local

In those tests, there are Feature tests for a production ready implementation of the package. There are no Unit tests at present.

You can also easily open a shell in the testing container by using the command:

composer docker-shell
